Double wired breaker
Double wired 15 amp Cutler Hammer breakers. Are there types of breakers that allow two wires and if so how would you identify the breakers in the panel? Thank You

Re: Double wired breaker
The only breakers I know of that are rated for two wires of the same size is the Square D QO series...could be others but ....

Re: Double wired breaker
Some, (maybe all new), Cutler Hammer CH breakers, 10-30-amp single pole, also accept 2 14-10 copper conductors. Those and the Square-D (QO and Homeline) are the only ones.

Re: Double wired breaker
BUT ... (that big 'but') ...
You DID notice that ONLY applies to the *15 amp* breaker, right?
Not listed or allowed for the 20 amp breaker.

As the original creator and poster of that highlighted photo (from May, 2005) I have to say you are wrong there. The wire size ranges apply to everything within that section...in this case 10 to 30 amps. Otherwise, the 25 and 30 amp breakers are allowed no wires. That wouldn't make much sense. |

Rich,
You want to take that one?

Re: Double wired breaker
Richard -
"The wire size ranges apply to everything within that section...in this case 10 to 30 amps."
So the chart is indicating a 30 amp breaker can have a #14 wire? I don't think so.

Aw c'mon guys. Use a little common sense here. Look further down the chart. Using your logic in the 2nd section, it's OK to have #14 on a 35 and in the third section, 50-amp breakers need 3/0!
It's the wire size the lugs in that section will accept...NOT the recommended wire size for every amperage breaker.
Sheesh! |

Re: Double wired breaker
I see what you're saying now. That chart is a tad confusing - at least to a semi-senile person like myself.

Re: Double wired breaker
The chart is not confusing, okay, I guess it is, because at least one here IS confused.
The chart says:
Ampere Rating | Wire Size Range
10 amp rating | (1) #14-8 (Jerry's note: That means (1), yes *1*, wire sized #14-#8.)
15 amp rating | (2) #14-10 (Jerry's note: That means (2), yes *2*, wires sized #14-#10. Note that the terminal on the 10 amp breaker is rated for a larger wire than on the 15 amp breaker, that's because IT IS NOT rated for (2) wires, just one wire.)
20 amp rating | (1) #14-6 (Jerry's note: That means (1), yes *1*, wire sized #14-#6. Note that the terminal on the 20 amp breaker is again rated for a larger wire than on the 15 amp breaker, that's because IT IS NOT rated for (2) wires, just one wire.)
25 amp rating | same as the 20 amp rated breaker
30 amp rating | same as the 20 amp rated breaker
35 amp rating | #14-2 (Jerry's note: That means (1), yes *1*, wire sized #14-#2.
Now, go down to the sub notes and you will see that sub note 1 means it applies to 1 and 2 pole breakers.
You will see that sub note 2 means that breaker (the one and only one rated for two wires) can use solid and stranded TOGETHER.
So, the 15 amp breaker *is the only breaker on that chart rated to TWO (2) wires, and, that applies to single pole and double pole breakers, and, that you can mix stranded and solid wires together.
BUT ONLY on the 15 amp breaker.
NONE of the other sizes.

If you are referring to me, Jerry, just say so!
"10 amp rating | (1) #14-8 (Jerry's note: That means (1), yes *1*, wire sized #14-#8.)
10 amp rating | (1) #14-8 (Jerry's note: That means (1), yes *1*, wire sized #14-#8.)
15 amp rating | (2) #14-10 (Jerry's note: That means (2), yes *2*, wires sized #14-#10. Note that the terminal on the 10 amp breaker is rated for a larger wire than on the 15 amp breaker, that's because IT IS NOT rated for (2) wires, just one wire.)
20 amp rating | (1) #14-6 (Jerry's note: That means (1), yes *1*, wire sized #14-#6. Note that the terminal on the 20 amp breaker is again rated for a larger wire than on the 15 amp breaker, that's because IT IS NOT rated for (2) wires, just one wire.)"
WRONG!!!
Let's take that 20-amp:
(1) #14-6 (3). My bold because you seemed to ignore that. The note (3) indicates it is for 3-pole breakers. Exactly where does that leave you for what's allowed for a single-pole 20-amp? Or 25 or 30 amp?
And if you insist on just reading straight across, please explain the "requirement" that 50-amp breakers NEED 3/0.
I have been wrong before but I'm not the confused one when it comes to reading this SIMPLE chart. I'm actually baffled that anyone would read it the way you are. However, for your benefit, I will e-mail Eaton tonight and see if I can get them to reply to this. If I'm wrong I will apologize profusely. Can I expect the same from you? |

Yep.
But I expect to see your apology tomorrow when they respond.

Got back into this one late tonight. What Jerry posted is exactly how I too read it.
(TO ALL) Please do not post apologies for your stated positions... if you are wrong, just post pictures of your old lady so others can gauk at her.  Or, if you have caught her with the mailman (delivering more than mail), please post those pictures as well  . Shoot, I have some I can't wait to post with old Debbie (my 'X') getting a physical from the whole Mormon Tebernacle Choir.

Re: Double wired breaker
Richard,
You are correct, 10-30 amp 1 and 2 pole breakers can accept a single conductor #14-8 or 2 conductors #14-10. If you see on the left hand side of the breaker if you are looking at the front, the wire capacity is molded into the plastic.

Circuit Breakers
I'm a home inspector and this has to do with residential breakers
designed for one or two conductors, and table 3-30 for the wire size
range under the lugs of CH breakers in particular. The table seems
clear to me in that all three options for 10-30 amp breakers applies to
all the breakers in that section. IE. All 10 through 30 amp, single
and double pole breakers can accept two 14-10 conductors. I have
another inspector (actually more than one) on a Home Inspection forum
insisting on reading straight across the chart, line by line, and saying
that only 15-amp breakers can have two conductors...because that happens
to be on the same line. I'm frustrated in my attempt to point out that
the chart makes no sense that way.
Perhaps you could view the discussion at
http://www.inspectionnews.net/home_inspection/electrical-systems-home-in
spection-commercial-inspection/669-double-wired-breaker.html ?
A simple answer from Eaton on the forum would be the ideal, but an
e-mail clarification that I can pass on would also be OK.
Your help would be much appreciated before I tear my hair out.
Thanks,
Richard Moore
