An electrical ground is essential in household wiring to prevent fire and electrical shock. Grounding is making sure all wires within a circuit are connected to a ground that reduces the voltage to zero. Older homes have more grounding problems. One of the simplest grounding problems to fix is making sure that all ground connections are correct.
Things You'll Need
- Screwdriver or Crescent wrench
Shut off the main electrical power.
Find the grounding rod driven into the ground. It is normally located outside the wall by the electrical panel.
Check the ground connection clamp. Reconnect the wire and tighten the clamp.
Check the ground wire running to the copper or galvanized water service inside the house. Make sure the connections are tight. Visually check to see if the ground wire is going around the water service and not through it. If the ground wire is running through the service, it must be moved.
Turn on the electricity at the main panel. Check the devices that were having grounding problems with a multimeter. Phone a professional electrician if this does not help with the grounding problem.
Tips & Warnings
- The ground wire should not go through the water service because of the rubber washers that prevent electricity from properly grounding.
- Make sure the electricity is turned off while checking the ground connections to avoid electrical shock.
