Basement Outlet Electrical Wiring

Electrical Question: I’m working on finishing my basement wiring and I want to run the electrical wiring for my outlets from the basement to the attached garage on the first floor.

  1. How can I best make sure that I leave myself enough wire from each outlet to make it to the breaker box?
  2. Should I install another circuit breaker box in the basement.
  3. I don’t plan to hook any thing up myself, just want to install the electrical wiring and staple it to the walls so I can install insulation.

Thanks for your help,

  1. Dave Rongey says:

    Hi Alan,
    Because this is an unfinished basement then the outlet should be GFCI protected, as well as the additional outlets. There are several types of cover plates available to accommodate the type of box that will be installed, which will be according to code for the conditions found in this location of the basement.

  2. Al says:

    I installed a 4 X 2 1/4″ metal box in an unfinished part of my basement for a sump pump to our new basement bathroom. This is on a 20 amp dedicated circuit. Do I have to use a GFCI for this outlet? I want to add a regular 20 amp duplex receptacle along with the GFCI and if I can do this, what kind of cover plate is used?
