I am upgrading my electrical box with more circuits, and circuit breakers. I would like terminate all the unused circuits wires in the electrical box panel with dummy circuit breakers rather than leave them dangling in the box. I would then terminate the unused wires in the attic within an enclosed terminal block in the attic. When I need to add another circuit in the future, all I have to do is run the circuit from the terminal bock, and replace the dummy circuit breaker with a real one. This avoids the hassle of running a new wire into the panel from the attic, and crowding the panel with unorganized new wiring, etc. I rather do it all upfront. Is there any problems with this configuration other than code issues?

    What wiring method were you planning to use for the run from the panel to the attic, and how many circuits were you planning to run this way? – ThreePhaseEel Jul 1 at 0:01

    What is a dummy circuit breaker? Where is this? – Jim Stewart Jul 1 at 0:22

    Jim asks a lot of questions, but "dummy circuit breaker" is new to me too. Only thing I can think is a circuit breaker that fills an empty hole in the panel. I just use real live breakers for that. – Harper - Reinstate Monica Jul 1 at 0:39
  • Also, what make and model is your breaker box? – ThreePhaseEel Jul 1 at 2:52
  • @Harper -- at least for QO boxes, there is such a thing as a dummy breaker -- it's a QO1DB if you're keeping score at home. – ThreePhaseEel Jul 1 at 2:52

Cap off hot and neutral

The hot(s) and neutral wires should be capped off and laid in the panel somewhere out of the way. Don't attach even the neutral; neutral can be a live wire in certain edge conditions. You can attach ground, however.

How long to leave the wires? Long enough so every hot and neutral can reach every breaker space in the panel. This should be standard operating procedure for every circuit anyway*. Neutral is one of these because AFCI/GFCI.

* which is incompatible with the "Captain Snippy" method of making wires minimum length for an "ultra-neat panel" -- but you don't actually get brownie points for that. You get brownie points for a functional panel.

  • It's an option, but tends to get messy overtime. The above approach increases the touch points in the panel, No offence to electricians, but I rather not pay an electrician to clean up my panel every time I need to add a single circuit, or worst create a mess overtime. I am looking for the best functional solution that is extremely efficient to add circuits, and avoids the spaghetti panel I have now. I appreciate the advise though, and may have no choice, but go in this direction. – AlwaysLearning Jul 4 at 1:32
