This has become an issue of debate here in teh office so I thought I'd
ask the public. What is the standard voltage for domestic supply in
North America? I've heard anything from 110V to 125V, and I've measured
it at anywhere from 115 to 122 so what is the "official" standard?

Cheers,

Chris


I don't know what the legal requirement is but when designing products all
companies I have worked for design for 120+/- 15%
or 102 to 134Vac. Generally when measured the voltage is in the 120s.


I've always used 115 ± 17, or 98-132

which is about the same as 115 ± 15%

Right now I am measuring 127.8 VACRMS in the shop. Its been that much
for a while. At home I'm getting more like 125VACRMS.

How long do your light bulbs last ?:-)

I just measured 119.5VAC, about 40' from a two-house step-down
transformer (which is the usual method in this area for underground
electrical distribution).

It's what you learn, after you know it all, that counts.
