>Anything designed for a 15A receptacle should not draw more than 1440W...

We had this discussion before and we agreed that they should have twenty amp plugs... and extension cords should not be less than 12 AWG Cu.

There are lots of extensions that turn a 15 A receptacle into three, six, or even seven receptacles. It would be easy to get 20 A on one of those. Amplifiers for a band come to mind.

I have one right here: Computer grade surge suppressor, Input: 115 V, 15 amp max, Output: 115 V, 15 amp max.
It's a "temporary power tap / TVSS" - says so right on it.

>Are hairdryers exempt?
Yes. They are not continuous loads, they are always attended while operating for no more than a few minutes per day, and they are unplugged and put away after each and every use.

Hmmm, come to think of it, most of them are not really exempt. Except when used according to the manufacturer's instructions...

Perhaps someone has one of those monsters and wouldn't mind testing the actual amps drawn while running. I would be interested to know the actual amps and volts of a running 1875 W blow dryer.
