Double Tap Clarification Please

Ok… I’ve gotten mixed messages from a newer electrician about this one. Guy said if it’s a breaker where the connection plate is made to separate 2 wires it’s allowed to be doubled up. I’ve been under the impression that if it doesn’t say “ 1 or 2 “ wires or only has a single wire picture like below it’s not. Any clarification on this so I can finally put this issue to bed would be appreciated. Thanks.


Square D typically has the “gull wing” connection for 2 wires.

Often they’re labeled like this:

As Larry Mentioned, it’s not a problem as those Square D breakers are designed for two wires.

Ya that breaker doesn’t say 1 or 2 like pictures and only has the 1 wire symbol. Most I see like that either have the double wire symbol or say 1 or 2 like the one pictured above so I wanted to be sure.

That’s because you are looking at the wrong place. The newer breakers have the allowed wire configurations on the side of the breaker

Square D type QO allow for two conductors to be connected as long as there sized according to the wire sizes used as part of the listing of the circuit breaker.

Thanks Guys. Appreciate the insight.

Square D and Cutler Hammer both manufacture breakers that are rated to accept two circuit conductor terminations or (double taps).
