No Electrical Grounding System

Homes built before the 1960s (and maybe into the 60s in some areas) probably don’t have an electrical grounding system installed. To find out, shut off power to your home at the main panel’s main breaker. Then remove the front cover of the panel. If you don’t see bare copper wires along with wires that have black and white insulation, then you don’t have a grounding system.

Adding Grounding to the Entire Electrical System

Adding a grounding system to an entire electrical system is a pretty big, expensive project. This is because you will need to run grounding wires to all the electrical devices in the home. This is a nearly impossible task unless you’re doing a substantial remodel that includes removing drywall. Inquire with a few electricians to determine if this is an affordable or practical thing to do in your home.

Adding Grounding Only to the Main Panel

An alternative to grounding all the devices in a home is to at least add grounding to the main electrical panel. This will add grounding protection to the main panel. Then, any new wiring installed can be grounded.

Adding Grounding to Only a Few Outlets

It is much more cost effective to add grounding to only a few outlets rather than the entire system. . The reason to do this is to protect delicate electronic equipment from power surges from events like lightning. A lightening strike on or near your home can destroy computers, TV’s, and other electronic equipment by sending s a surge of electricity into the devices that can’t handle it. You need two things to protect them:

  1. Surge Protector
  2. Grounded Outlet

The surge protector is the device you can buy to detect the power surge and send it to the ground rather than the electronic devices. Plug them into outlets in your home and then plug devices into the surge protectors. However, the surge protectors must be plugged into grounded outlets to do their job.

Adding grounding to specific outlets may be easy or difficult depending on the location of the outlets, but protecting expensive equipment is often worth the effort. An electrician can ensure this is done correctly.
