How Do I Wire a Siemens Breaker Box?

For residential applications, there are only three widely trusted brands, those being GE, Square D and Siemens.
Siemens panels are standardized and can all be installed in a similar fashion, with a similar layout to one another. The standardization means that professional electricians or intrepid do-it-yourselfers don’t have to figure out where everything is every time they want to install a new electrical panel.

Step 1

Turn off the power coming to you home.

Step 2

Feed the main power cable into the Siemens breaker box and use a cable clamp to secure it.

Step 3

Strip about an inch of sheath off each wire in the cable, exposing the bare metal.

Step 4

Slide the black and red striped wires into the the main bus bar terminal blocks, at the top center of the panel, and tighten the lugs on the terminal with a torque wrench.

Step 5

Slide the white wire into the neutral bus bar on the upper right side of the panel, and the bare ground wire on the upper left side of the panel, and tighten both of those using the torque wrench as well.

Step 6

Replace the front panel of the box.

Step 7

Turn the power to your home back on.

Things You Will Need

  • Torque wrench
  • Utility knife
  • Wire strippers
  • Cable clamp


  • Be absolutely sure the electricity is really off before attempting these steps, or you will be electrocuted.
