Wire extensions with wirenuts in breaker panel

dalepresFebruary 12, 2011

I am going to replace my 100 amp service with a 200 amp service, meaning I will be changing out my main panel in the house.

If it turns out that the existing circuit wiring does not reach the breakers in the new panel, is it legal, according to the NEC, to use jumper wires connected with wirenuts inside of the panel to extend the branch circuit to the breaker?

Yes, it is permitted. Most AHJs will not object as long as the wiring in the panel is neat and orderly, though some have a problem with an 'excessive' number of these extensions, so I would keep it to a minimum.

Thanks, Randy.

Where I live there are no inspections but I want to be as safe as possible - even more safe since it is all up to me.
