Code Question Of The Day

Tuesday, June 28, 2011
Question:

Subject: Double wire on a breaker

Charlie, I read your column every day, it keeps me up to date. Can you tell me - where in the Code Book does it say about two wires on a breaker. I know it is not allowed but I can't back it. I look through the book with no luck

Thanks
Lars from N.J.

 

Answer:

Hi Lars, thanks for participating. Are you a civilian or a military person at Ft Dix? Either way, thank you. Terminating more than one conductor on a terminal is permitted if the terminal is identified for such use. The last sentence in Section 110.14(A) says "Terminals for more than one conductor and terminals used to connect aluminum shall be so identified."

 

Section: 110.14(A)
