doubling on circuit breakers

wire color code inconsistancy

Ungrounded wire colors are, by and large, not really an NEC issue.

But I did notice a lot of the numbers on the wires don't match up with the breakers numbers (which don't follow the 'ordinary' numbering methods).

The issue is with the breaker lug not the panel. The wire capacity is stamped on the side of the QO breaker, they (10-30A) have been rated for two conductors for about forty years.

Same with C/H.

Is it just me, or are two of the breakers that are doubled up tripped?

That's the most serious possible problem with what HI's call a "double tap."

 

[LarryFine]

For the breakers shown (this is the same for NQ types) refer to Table 1.3 on this page for the terminal wire limits

I noticed that they specify only copper for the (2) wire allowances.

I noticed that they specify only copper for the (2) wire allowances.

And I believe that is true of C-H also.

Its pretty ovious when a termanal or breaker is rated for two wires, When youve been in the trade a while this will become more clear as it has for me..

You have to be careful and make sure that the terminal is listed for more than one conductor per section 110.14 (A). It may look obvious but it may not be listed .
