The Americans also have widespread use of alumin(i)um wiring
well that partal fact it was common in late 60 to early 70's but really the biggest curpit was inproper use of device and termation set up that what most common source of fire or overheating connection
most home where still have alum branch circuits have to use the devices marked CU/AL otherwise most peoples try to fixed themself and end up a more mess than it worth it.
to splice between alum and coppper wires is very tricky procudure it need specal wirenuts or ireversable crimp one of the two [ the UL have isuse with purple wirenuts]
please do recheck the wiring facts before you post it ok ??
many thanks
Merci , Marc
