Home Electrical Ground System

Electrical Project: Electrical Panel Grounding.
Skill Level: Advanced – Best performed by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical wiring.
Precaution: Working in an energized panel is dangerous. Turn off the Main breaker before wiring or working or making connections. Components inside the panel may be still energized even when the main breaker is off.
Notice: Installing additional outlet wiring should be done through the local building authority, according to applicable local and national electrical codes, with a permit, and have required inspections.

  1. joe says:

    Is there ever a time when a residential sub-panel would require it’s own ground rod? Such as in a detached builing from the main panel at the house?

  2. Dave Rongey says:

    Yes Joe,
    If a ground wire is not bonded back to the main panel, and there is an electrical service that is more than one branch circuit, (such as one 20 amp 120 volt circuit at a detached building), then a ground rod must be driven.
