Good link Paul, that I reference occasionally too. Only down side is limited table values. Many (including me) highly recommend an HI at least have the basic CodeCheck reference with them on an inspection ... very handy ... http://www.taunton.com/store/pages/070680.asp

P.S. I also think Dan was right on the money, and should have asked the experts to put things in writing (assuming the one noted as a problem with 30 Amp wire and a 40 Amp Minimum Ampacity wasn't #10 Cu THHN in conduit which is good for 40A).

Hey Paul, how current is that edition of Code Check? Are the referenced codes current?

[Paul W. Abernathy]

Not sure Brian.....I will look it over

Out of date, I know as I used to have that one.
Good reference but be careful.

Ok Joe then where is the aforementioned code check currently current?

30 amp wire:
I could put a #12awg on a 60 amp breaker using the below reference.
440.22

(A) Rating or Setting for Individual Motor-

Compressor.

The motor-compressor branch-circuit shortcircuit
and ground-fault protective device shall be capable
of carrying the starting current of the motor. A protective
device having a rating or setting not exceeding 175 percent
of the motor-compressor rated-load current or branchcircuit
selection current, whichever is greater, shall be permitted,
provided that, where the protection specified is not
sufficient for the starting current of the motor, the rating or
setting shall be permitted to be increased but shall not exceed
225 percent of the motor rated-load current or branchcircuit
selection current, whichever is greater.

Exception: The rating of the branch-circuit short-circuit

and ground-fault protective device shall not be required to
be less than 15 amperes.

Was just information al reference for the usual HOME INSPECTOR...not for electricians...lol.....

Yep...Mike....somewhere in the boards I did a long explanation of that and gave some calcs samples as well......not sure where I stuck them now...lol

The issue Dan posted that I commented on was an installation that did not appear to comply with the equipment label. He described it as a 30A wire when the listed minimum circuit ampacity on the nameplate was 40A.

AND the wiring inside at the panel box was a 30 Amp wire.

Normally an HI will think of #10 = 30A ... but if it's typical #10 Cu wire fished through conduit (not a cable) for an AC circuit it would have an ampacity of 40A (temperature derating and voltage drop aside).

JMO & 2-nickels ...

Bump

[tdietrich1]

Thx for the bump.

I don't plan on using this too much, since it address 2000 IRC and at best 2002 NEC, but it's nice to have a simple to decide I like it. I might run out and get the book for some nice relaxing reading. Relaxing compared to the 2006 IRC I've been thumbing through for the last week.

What a geek!
