Arlen-
 
Take the old breaker into an Ace Hardware Store. You want something
that has the same mounting and terminals, rated for 35 Amps and at least
240 Volts.
 
The 43 "TRIP" Amps would be nice, but is not the most important
parameter. Hopefully you do not normally run the generator close to its
limit.
 
I would not be surprised if Ace had the exact breaker for around $25.

Thanks Clare for that purposefully helpful lookup, where I may have made an
inadvertent typo at some point, as it's AA2 (2 pole), not AA3 (3 pole):
o AA2-B0-24-635-5D1-C <https://i.postimg.cc/vmTTdpdB/breaker02.jpg>

Mouser doesn't stock this part, but they do have a decent datasheet:
<https://www.mouser.com/datasheet/2/65/A-Series_Details__26_COS_030314-345780.pdf>
 
I will need to call Mouser during business hours for price & availability:
o (800) 346-6873, (817) 804-3888
 
Unfortunately, Newark also says "Not Normally Stocked":

But at least they list a price, where, the going "fair" rate is about $100
o $ 92.45 onlinecomponents.com
o $ 95.53 newark.com
o $137.07 jackssmallengines.com
o $233.45 ordertree.com
 
The question is mainly HOW do you guys get hard-to-find electrical parts.
 
BTW, the smoke is everywhere easily smelled, strongly in the air, with that

Where do you source circuit breakers that are NOT in typical box stores?
o Carling AA3-B0-24-635-5D1-C (do you have a decoder for that number?)
 
PG&E has currently cut the power to us in California where this is the 31st
sustained power outage in three years (of more than a day each, generally),
so my generator has been doing triple duty as the backup source of power.
 
Over time, this 35 amp ganged circuit breaker partially broke inside.
<https://i.postimg.cc/ryNkQQvY/breaker03.jpg>
 
It has "Carling Switch" molded on one side:

And this barely readable paper label on the other side:
<https://i.postimg.cc/vmTTdpdB/breaker02.jpg>
 
The best I can make out from that data are these specs:
Carling Switch Inc.
AA2-B0-24-635-5D1-C
FL AMP 35
MAX VOLTS 227 (? hard to tell)
HERTZ 50/60

TRIP AMPS 43 (? hard to tell)
Mexico 9513 (probably the 13th week in 1995, likely original)
 
I called Generac's 24/7 live hotline, but they can't give me any more
information than the owners manual, parts diagram, and references
888-GENERAC (888-436-3722) extension 4, extension 2
1-262-544-4811 extension 1, extension 2, extension 4, extension 2
 
This is the relevant page out of that Generac Owners Manual they sent me:

o #5, Generac Part Number #74969, 35 Amp Circuit Breaker
 
Generac suggests these two outfits, who seem to charge astronomical prices:

----------------------------------------------
 
There's no point now. I have checked all 6 of those transistors and found
one faulty one as described. The question in my mind now becomes, "can
that one transistor (Q9) being partly shorted cause the voltage readings
on the other transistors to be so far out of whack?" Now most people
would probably say "just stick a new transistor in there and see if it
works" but I'm going to Spice the voltage-to-current section just out of
curiosity. Since I'm not a repair tech and time is not a factor I can do
this.
I'm lucky to have an identical board, the Y-amplifier, which is identical
in every way except that it works so I've been able to get some useful
values from measuring it under power and getting meaningful and sane
voltage readings from it to compare to the faulty one's measurements
which are all over the place.
The simulation is almost ready to run but I have other things to do right
now so it'll have to wait until tomorrow.

Cursitor Doom <curd@notformail.com>: Oct 25 03:56PM

So I've had to pull 6 transistors one by one out of this amplifier board,
in the strong suspicion at least one of them was faulty. They all tested
fine - until the last one (typical!). Anyway, these are small signal PNP
BJTs in TO-8 tin cans. The last one checks out fine for base-emitter and
base-collector junctions giving about 650mV in one direction only on the
diode test setting - I very nearly didn't bother testing further at this
point, given it was looking increasingly futile. Anyway, for the sake of
completeness one last check across the C-E terminals and I got 295mV both
ways! Double checking on the resistance range confirmed 600 ohms between
C and E both ways. I've never known a BJT fail in *this* way. Has anyone
else?

Well I don't do repair work for a living so defer to your wider knowledge
of the subject. I just find it baffling how such a transistor can give
readings like those I described, with a Rc-e lower than each of its Rc-b
and Rb-e readings!

It wouldn't be worth if for the number of times a 'mass extraction' like
this has been necessary, which before this happened was zero.
 
It would be nice to have *all* the meters in the Peake range, but on an
occasional need basis I can't justify it.

Probably. Did I write TO-8? I meant to type TO-18. It's a 2N3251 and in

expect with a design by Hewlett-Packard.

I ended up surrounding the HV exit wiring from the box with heavy duck
tape, formed into a circle, and the wiring in the center. Then, I
poured in epoxy to a depth of 1/2". That formed the new insulator and
extra sealing. You can't see it in the video though as all that is
shown are the HV wires coming through the larger containment PVC box and
up alongside the electrode posts. It is only rated 40 KV TV wiring
(like used for TV HV multipliers), so I have to keep my hands away or
will get weakly sparked.

By the way, for the people who suggested retaining paraffin instead of
going back to mineral oil, I am actually too curious to let that go! If
I can find two HEI coils at the junk yard for cheap, I am going to
simply use an old tupperware or even dollar store container for housing,
and then use the stove and oven once again for paraffin potting. I'll
be able to easily swap out my existing container for a wax filled one
without having to build all new circuitry. So, if I hurry and pot it
before it starts getting really cold here, I'll be able to see how it
held up over winter when I check it out next summer. As I said before,
where I have the demonstrator stored isn't under the best of climate
control, so temps will range from upper 40's to high 80's depending on
time of year.

This is where Usenet potluck sharing shows its value:

This is what I love about the idea of coupling a fast but inexpensive
switch to a separate access point, such as is shown in this picture:
<https://www.mbreviews.com/wp-content/uploads/2017/06/ubiquiti-edgerouter-x-6-1.jpg>
 
Note: You can put that NanoBeam NBE-M5-16 either on the POE out port, or,
you could put it on ANY port if electricity is near the location of the
transceiver, where the advantage of the POE out port is that you the
transceiver can be placed in a location that doesn't have mains power.

The one nice thing about all this Ubiquiti equipment is that they're like
hammers and screwdrivers, in that whenever you have a need, they seem to be
versatile enough to do the job well.
 
I don't have the speed needs that Mike has, but I love plugging "stuff"
into a switch where, for example, this is a radio I'm erecting outside that
is connected to a switch inside, which will paint the house from the sides:

Hi Jeff,
 
I know what you mean about getting ready for the PG&E outage today!
 
Up here, we all have generators, because our power goes off on average once
a month for a day or two each time (I could email you the PG&E-supplied
accurate spreadsheet of just the last 30 sustained power outages, for
example, which I provided to the CPUC to show how PG&E provides unreliable
power at top-tier prices).

Fair enough.
 
I like to explain things, to people who care to learn, and I love even more
being able to do stuff that people don't normally do (such as what these
radios allow for).
 
I admit I'm terrible at dealing with the trolls though, as it's

Yup. I understand. I still remember you wrote the best description on all

the "power" figures, where that's where I learned only the FCC knows for

Understood. And accepted.
 
There are so many options to these radios that I don't even know all the
things they can do for us, where I mostly use them for three things:
1. Point to multipoint (instantly adding an access point to "an RJ45")
2. Point to multipoint (instantly bridging Ethernet to WiFi networks)
3. Point to point (for longer LOS hauls, where mine is 6 miles only)
 
But there's a LOT more we can do with these radios (e.g., they're routers
too, and they are repeaters also, etc.).

Yup. You and I went over these apps in gory detail a few years ago.
 
Where I'm glad you care about your credibility, as I do, and where you
listed the unique name for the WiFi Analyzer app you like, as I have, oh,
let me check, give me a second ... ok... I have 6 apps alone named exactly
that (i.e., "WiFi Analyzer") on my Android phone at this very minute:
<https://i.postimg.cc/ZqH1RDNv/debug-wifi-on-android.jpg>
o Wifi Analyser <com.keuwl.wifi>
o Wifi Analyzer <com.farproc.wifi.analyzer>
o Wifi Analyzer <com.farproc.wifi.analyzer.classic>
o WiFi Analyzer <abdelrahman.wifianalyzerpro>
o WiFi Analyzer <uk.co.soapysoft.wifianalyzer>
o WiFi Analyzer <com.wifianalyzer.networktools.networkanalyzer>
 
And yet, on iOS, there are zero. Sigh. The iPhone users don't even realize
how utterly primitive the app choices are on their beloved platform.
I test software like you test hardware, so I know them all.
 
I just wish my iOS iPads could have this kind of modern functionality.
Sigh.
 
(What's odd is that the Apple Apologists incessantly claim the
functionality exists, and they even did a Youtube video condemning me
because I proved they simply fabricated imaginary iOS functionality, as
they always seem to do - which is really odd for adults to try to pull).

You are correct that the Apple philosophy is to limit what you can do,
but what's strange about the many Apple Apologists is that they fabricate
imaginary iOS functionality all the time....
 
Why?
I don't know why.
 
But they do it all the time.

I care about my credibility - which is why the very fact that there are so
many trolls who infest this thread who don't give a whit about their lack
of credibility astounds me - since adults are supposed to provide value.
 
Sigh.

Now that's interesting.
 
If you were an Apple Apologist, I would have to flip a coin to see if I
believed you, but since I know you, for many years, to be credible (as am
I), I believe you a priori.
 
Thanks for that advice where I will take it to heart since you have always
been credible, if a bit self effacing (I love the photo of you in your park
ranger outfit by the way ... it was so 70s ... but it makes you human on
Usenet!). :)

Hehhehheh... I didn't quite get all the technical jargon, but I did get the
jokes as the repeater does double duty, hence half the throughput.
 
I've never put the Ubiquiti radios on anything but bridge or access point,
so it's good information to know, where I love that these tools, like an
Android phone, turn out to be so versatile that they do far more than we
know at first.

I've never used this, but it seems useful if we plug it into a switch where
we can have multiple devices on that switch, where, I guess, each gets its
own IP address from the Ubiquiti router.
 
Is that about right for the router (given it's only one RJ45 port coming
out of the radio)?

What I'm guessing is that the "router" versus "soho router" option must be
giving the Ubiquiti radio "more options" that are related to routing.
 
As I said, I have never used that "soho router" option in the Ubiquiti
AirOS software, so I don't even know if I've ever needed to use it as a
"Soho router" and didn't know it.

Thanks for that advice, where you've helped me and many others cheerfully
over the years, where I still remember when I was trying to change MAC
addresses and IMEI numbers (many years ago when it mattered), and you
advised against it (and you explained that the one MAC address you can
change isn't the one you want to change, etc.).
 
My point is that your advice, over the years, has always been credible.
As am I.
 
Thanks - and - well - we were 'scheduled' for that PG&E outage, but we
didn't get it yet, so I had better send this off to you now before it
happens.

Hi Mike,
 
I understand that every situation is different, and, one of my key points
on versatility ot good tools is that even your situation is different today
than it might be five years from now (where you can repurpose stuff you
bought if it's versatile).

Understood. The beauty of the switch (or router) being separate from the
access point is that you can place the access point anywhere you like.
 
One thing you might consider, Mike, which works GREAT for me because I
don't want to 'climb through walls' is you can position the access point
OUTSIDE the house pointing back at the house!
 
This idea works GREAT for me!
 
I'm nestled into the side of a hill, which helps, as I can see the roof
from my back yard, where every instance is different topographically, but
even on a flat yard, you can still paint the entire house with WiFi simply
by snaking a cat5 cable to the clotheslines pole, so to speak.
 
The geometry works out such that one side of the house only has a wall and
windows to penetrate (out here, windows are solar reflective/absorptive by
code).

Understood, Mike, where it's refreshing to converse with someone like you
who has real needs and thinks of real solutions instead of having to deal
with the too many trolls who outnumber us 20:1 who simply post on Usenet
for their own amusement.
 
Given your needs are simply that the antenna needs to be in a different
location from the router/switch, I'm curious of you've looked at those
routers where the antenna itself is easily detachable and relocatable?

Hi trader_4,
 
This isn't our first rodeo with you trader_4, where you love to troll.
 
You play silly games like removing the experts from the newsgroup list,
and then you play your endless silly games where you expect me to teach you
802.11 WiFi when you can't even comprehend the simplest things about it
including lots of details which the experts kindly outlined rather well.
 
If you really wanted an answer, instead of just wanting to troll, you
wouldn't have removed the experts from the Newsgroup list who have better
social skills than I do when dealing with common worthless trolls like you.
 
The experts have already explained, numerous times in fact, the naming
conventions, which you've wholly ignored because you only want to troll.
 
I went to a lot of trouble to put the explanation into place below, so I
hope you appreciate the effort, as I did it for you, trader_4, and for the
public record, which will be archived 'permanently' at these sites:

Here is my summary of what "I do" using 802.11 Wi-Fi for this one device.
 
The "NanoBeam M2" on the left is what this discussion below is describing:
<https://i.postimg.cc/905nFgxX/nanobeamnanobridge.jpg>
 
It is the PowerBeam (aka PBE-M2-400) shown in many of my uploaded photos:
<https://i.postimg.cc/CLBXc080/antenna03.jpg>
 
It's also that spare PBE-M2-400 on the shelf at top right that I'm using:
<https://i.postimg.cc/XJChDCPr/spare-access-points.jpg>
 
Experts showed it also goes by the name of NanoBeam M2 (FCC ID SWX-NBM2HP):
<https://i.postimg.cc/0NYJn7mF/nanobridge-nanobeam.jpg>
 
These are the 802.11 WiFi settings I'm using right now for that PBE-M2-400:
<https://i.postimg.cc/Bv0wZbDh/pbe-m2-400-802-11-wifi-setting.jpg>
 
It works just fine, for me, as an 802.11 WiFi AP or 802.11 WiFi bridge:
<https://i.postimg.cc/Dzq9Bsjs/pb-m2-400-nanobeam.jpg>
 
Here it is as a working bridge between a new laptop & an 802.11 WiFi AP:
<https://i.postimg.cc/vT0Krpfc/laptop-nanobeam-horn.jpg>
 
Here it is as a bridge between an old laptop & an 802.11 WiFi access point:

Here it is illustrating adding an 802.11 WiFi AP to a dumb switch:

This is the PBE-M2-400 Quick Start Guide
<https://dl.ubnt.com/qsg/PBE-M2-400/PBE-M2-400_EN.html>
 
Nothing will work for you; but it works just fine for me, either as an
o 802.11 WiFi access point, or as an
o 802.11 WiFi bridge (bridging an RJ45 port to WiFi)
 
I'm sure if I enabled AirMax, I could use it for a long haul PtP too.
o Either sans 802.11 WiFi support (for AirOS versions 4.0 and above)
o Or with legacy 802.11 WiFi support (for AirOS versions 4.0 and below)

Arlen _G_ Holder <_arlen.george@halder.edu>: Oct 27 08:14AM

UPDATE:
 
Hi Jeff,
 
As you're aware, PG&E has cut our power here near Santa Cruz and the hills
surrounding Silicon Valley, where the fact I'm able to post this means I
figured out what the problem was with the power from the generator not
getting to the house.
<https://i.postimg.cc/G37D8Jq6/breaker01.jpg>
 
I had _thought_ it was the transfer switch, simply because a couple of
those SBS-2 600V 2Amp fast acting ferrule fuses were missing, but it turns
out that when I replaced the two missing fuses, nothing changed.
<https://i.postimg.cc/ryNkQQvY/breaker03.jpg>
 
It turns out that half of the part #5 was broken inside (invisibly so)
<https://i.postimg.cc/qq326cBh/Generac-Control-Panel-9067-9-16345-Page-19.jpg>
o Generac Part Number #74969 35Amp Circuit Breaker
 
I'm not sure if that's the same part as "CB1" in bottom right of this page:
<https://i.postimg.cc/Zqf00Y5K/Generac-Generator-Wiriing-Diagram-9067-9-16345-Page-14.jpg>
 
But it's Generac Part Number 74969 35 Amp Circuit Breaker (2 ganged poles),
which disconnects 120VAC power based on my measurements on the breaker.
<https://i.postimg.cc/vmTTdpdB/breaker02.jpg>
 
This is what it says on the circuit breaker itself:
Carling Switch Inc.
AA2.B0.24.635.5D1.C
FL AMP 35
MAX VOLTS 227 (? hard to tell)
HERTZ 50/60
DELAY 04 (? hard to tell)
TRIP AMPS 43 (? hard to tell)
Mexico 9513 (probably the 13th week in 1995)
 
Where the complete circuit diagram is outlined already in this older post:
<https://groups.google.com/d/msg/sci.electronics.repair/QhSY4KWN-Kw/P-R0-y6CBAAJ>
 
In summary, there were two problems concurrently:
1. The fuses were missing in the transfer switch
2. Half the circuit breaker was internally broken
 
The result was that there was no electricity in the house when the PG&E
power went out until I replaced the fuses; and there was only electricity
to half the house. The 35Amp ganged circuit breaker has two "LINE" and two
"LOAD" terminals, where, each circuit breaker innervates half the house.

Interesting, so even the welded wires still have to be insulated then.
As you say, the reason for the faulty readings I am getting.
Unfortunately, I don't have anything decent other than shrink tube and
leftover high temp RTV to coat them with, so I think it's time for a new
probe.
 
I will point out that the group has been a big help in informing me how
