(they're not according to the 125% ampacity rule Table 210-21 (b) (2) 1999 National Electric Code NFPA 72, unless they change the plug to a 20 Amp plug)

You were going to update your website, weren't you?

I've changed the "72" to "70" (now how'd that happen?) and got rid of the redundant "that" in the first line...

Anything else?

How about "Contractors Electrical Equipment?"

Virgil, God loves Mountaineers. Otherwise, about 75% of this state would have burned down already.

'Course, the smart move would be to go short (stock market term) on any company that sells fire insurance in WV.

Few things are harder to put up with than the annoyance of a good example.

Tom, boy, you are so right...

Defies the laws of physics...some of the stuff I see!

Actually, yes.

Blow dryers are not actually in violation as described.

I have personally run a blow dryer for more than three hours as a kid when we were out of wood and I was cold... Don't underestimate the stupidity of the general public! (You must've never had pipes freeze either...Heck for that matter, I've done it as an adult!)

So there! It is a continuous load...

Furthermore, in my opinion, any thing that can be turned on and left on without it shutting itself off within three hours with a timer, thermostat or some type of control, would be considered a continuous load.

I realize that it is very arguable, that's why I said that there is controversy on whether they are legal.

And don't forget to exaggerate for clarity!

Where connected to a branch circuit supplying two or more receptacles or outlets, a receptacle shall not supply a total cord- and plug- connected load in excess of the maximum specified in table 210-21(b)(2).

Circuit Rating Amperes 15 or 20
Receptacle Rating Amperes 15
Maximum Load Amperes 12

Circuit Rating Amperes 20
Receptacle Rating Amperes 20
Maximum Load Amperes 16

Bathroom Receptacles are permitted to be shared on one 20A circuit. And when shared, I believe one can use 15A recepts...

12A @ 120v = 1440w
16a @ 120v = 1920w

If they are to be under the 20A rating, they need a 20A plug... Do they not?

Bill, just what were your arguments about this again?

I apologize for my digression...

Please go here for a reprise of an old thread on hairdryers...

Were you using an extension cord?

>Don't underestimate the stupidity of the general public!
It's not stupid. If you had no wood, then the ambient temperature was probably well below 20°C giving the wiring increased ampacity.

>(You must've never had pipes freeze either...
Trailer folks.

>It is a continuous load...
That's what I said about leaving the hot water running.

>in my opinion, any thing that can be turned on and left on without it shutting itself off within three hours with a timer, thermostat or some type of control, would be considered a continuous load.
That is my view as well for purposes of sizing the conductors. Say, were you quoting me?

Anyway, when thawing pipes or in a cold house, you get a 25% uprating in ampacity from the DSpark table so long as you aren't using an extension cord of a gage less than the gage of the fixed wiring. So carry on.

Dspark... you are too funny!

LOL!

(Would you point me to the place from where I may have plagiarized you?)
