He said a person could pigtail 2 wires and take one wire from that to the breaker but that was it as far as the NEC allowance.

I thought as long as the breaker was designed for two wires one could attach two wires to that breaker.

Does anyone have the code section that makes the allowance for 2 wires on one breaker designed for that?

Or is he correct?

He is mistaken, note the last sentence of 110.14(A)


NEC
Quote:
110.14(A) Terminals. Connection of conductors to terminal parts shall ensure a thoroughly good connection without damaging the conductors and shall be made by means of pressure connectors (including set-screw type), solder lugs, or splices to flexible leads. Connection by means of wire-binding screws or studs and nuts that have upturned lugs or the equivalent shall be permitted for 10 AWG or smaller conductors.

Terminals for more than one conductor and terminals used to connect aluminum shall be so identified.


If the terminal is identified for two you may use two. ![icon_cool.gif](upload://oPnLkqdJc33Dyf2uA3TQwRkfhwd.gif)

Could be that the local inspector doesn’t allow it.


"National" in the NEC doesn't really mean anything.

He's a friend of mine and we were talking specifically about the NEC but you're right some inspectors may not allow it.
