    Splicing In Residential Service Panels?

    Does the NEC allow splicing of wires inside a residential service panel? If yes, are there rules to follow. Can I combine two branch circuits in the service panel to make one circuit, thus freeing up a circuit breaker?

    Yes you can, nowhere in the NEC does it say that you cannot splice in a panelboard.

    Which 2?

    By the time you run around checking everything, a tandem CB might cost less.

    A tandom CB cannot be used in this panel.

    There are rules in the NEC regarding splicing in panels.

    The rules for splicing in any panel can be found in 312.8 2005 NEC. Be sure to read the entire section.

    Then you better figure what 2 loads you are combining ...aka, more time...aka, more money....and possibly an unhappy customer when all is said is done:

    As Iwire says. 312.8 with splicing etc. But, IMO if you are joining cicuits together in a panel to a OCPD, you're not using it as a junction box. It would be the same as if in a switch box with multiple feeds.

    I remember the same line of thinking about making a splice in a LB. The word on the street was no. NEC will allow if the condulet is listed. I even seem to remember the question on license exam, if memory serves.:rolleyes:

    two circuits...

    there are limits to how many receptacles can be on a branch circuit, depending on the ocp.

    dab, there is no NEC limit to the number of receptacles on a residential branch circuit.

    In other than dwelling units each duplex receptacle counts as 180 VA.
