Multi-Wire Terminal for Miniature Circuit Breaker

[HecThor]

I've been seeing alot of MCB's(miniature) holding two wires per terminal and the application is Solar PV, is this allowed? All I know is that the breaker should be listed for multi-wire connection per 110.14(A), do you know of any certification/listing that pertains to this? not sure if this isUL508A & IEC 60947-2. Thanks

if you look close enough in the instructions it will tell you what size wires and in what combination can be connected to it. All of these style of circuit breakers I have used allow two wires. It also depends on the size of the wires. Sometimes you are allowed to have one number 6 or two number tens or smaller.

Ul508a has nothing to do with it.

Noted on this. Thanks a lot!
