The first is one Peter pointed out; the U.S. was wired early and without codes. A lot of that wiring still exists and even if thoughtfully wired, is still a hundred years old. Back in the 80s we rented a store front that was still cap and tube wiring from the 1920s, and the new owner wanted us to sign a triple net lease (which means we were liable for any repairs to this late 19th century building, including the wiring and plumbing). Both still were serviceable but we left and bought our own building. Our pre-50s wiring has pretty much all gone now. The rubber used was evidently inferior to the US stuff, when encountering 50s wiring in the 80s it was always in a terrible state with a lot of the rubber insulation fallen off. K&T may be ancient but from what I've seen (on the net) of it it appears to be basically sound in design. Our pre-55 wiring generally wasn't. > The large city closest to me uses special equipment for detecting electrical fires. The city includes a large percentage of homes that were built in the late 1800s through the early 1900s. The fire department has infrared scanners that they use to detect heat behind walls during a survey of old wiring. We don't have that, but testing resistances of circuits accomplishes much the same thing. Also the police here do infra red flyovers and sometimes pick up on excess heat. I assume they're looking for drug farms. > Second thought is the definition of electrical fire and the cause. I don't know if there's an international watchdog commission that compiles the data or if the data is submitted by each country independently. Perhaps the definition of what exactly constitutes electrical fires. > I don't know about the U.K., but we have a lot of dullards here that run extension cords to high wattage electrical supplemental heaters for when they can't afford a tank of heating oil or propane. So I wonder how many of these failures are from external misuse or internal infrastructure failures. I can't tell you how many times I've pointed out worn out wall sockets or melted three way extension cords that were ready to burst into flames to customers when doing home service. From what I've seen of US wiring the reason seems pretty obvious, most of it is done to lower safety standards than here. The only odd thing is that Americans seem unable to accept that. Typically they lapse into being abusive when such things are pointed out. NT |
