My guess here is they will transition when the transfer switch is FULLY on in either generator or utility position. This would jive with your you're trying to do. Indicating something like "in the middle of switching" would be pretty useless, and something the controller could detect itself. |

Even got the green sticker on the main panel to prove it. Eric |
Veek M <veek@dont-use-this.com>: Jul 03 03:07PM http://www.agnesbattery.com/sfindustrial/stanqueen.html For a 12V 150AhC10 battery - we charge at 10%, 15A till the voltage/cell reaches 2.36V. So why do we have this 'Minimum Ah input During Initial Charge' setting? In another spec it says: "Minimum Ah input 450% of C10 capacity" for a 200Ah C10 battery. ---- 450% is something like 900Ah or 4.5 times the base Ah.. wth? |

Assuming he means some kind of absolute minimum charging current.. how would that make sense because the battery starts charging at 10% of C10Ah which is huge.. 15A.. Also, if the battery is comprised of numerous cells (12V-nominal/2.36Vpc gives the total cells - 5 cells in series.) So 15A is the charge current to all the cells.. ergo.. (and another Q, how does he check the per-cell voltage is 2.36V because if they are in series.. does he just assume when he sees 12V across all of them?) |
root <NoEMail@home.org>: Jul 03 01:04PM My Garmin Foreerunner uses a chest belt to capture pulse. The belt broke and I would like to try to glue it together with a conductive cement. I see there are conductive epoxy glues and I would like comments on your experience with such. Thanks. |

Agreed. One larger switchable bank at a plant will be cheaper and cover more possibilities than trying to connect capacitor banks at all motors. > I doubt it is cost effective to put correction at motors in a house. Yup. The largest motor I can think of in a house might be the compressor in a split airconditioning system. Those always have dedicated runs of power so they're more like an industrial schenario where wiring is run as needed, dedicated and properly sized to the intended load in the first place. |

It simply is not > worth it. We had a mini-mill in the north side of Chicago until recently. They'd do the melts at night for 1) better electric prices and 2) it was the only time of day their capacity needs could be met, even in an otherwise industrial area. I never saw the electric meters, but the powerlines feeding the complex had lots of instrument transfomers installed, way more than you'd usually see. Even after the building were completely demolished there was a mountain of power factor capacitor piled up in the gated off, otherwise vacant lot. > possible way to cheat and addressed it.

I want to know all about how to steal $2 of electricity per month with complex devices. |
