The Essential Grounding System of a Home

Skill Level: Intermediate to Advanced. This electrical project is best performed by a Licensed Electrician.
Tools Required: Basic Electrical Hand Tools and a Voltage Tester
Estimated Time: Depends on personal experience and the number of switches and outlets being replaced.

Correcting an Ungrounded Condition of Home a Electrical System

With this information I think you’ll agree that the ground wires of your home electrical wiring system are not bonded which in this case cannot provide the protection that a ground system provides. I would have this taken care of.

NOTE: A electrical contractor would know how to take care of this for you and inspect the integrity of the ground system at the main electrical panel which is vitally important above.

Question of the Day

Wiring a Switch for an Air Compressor

Wayne asks:
I am wiring my 240volt air compressor using 10/3 to a lighted 30 amp switch to place by exit door to turn off when im away.
My question is: when I wire the switch I will have essentially two hots, do I place both the black and red on one screw and the black and red on the other?
Also its the lighted Leviton 3032-plr, a lot of the comments say I need to use the neutral to operate the light.
I dont know what to do with that.
Thanks for your help.

Dave's Reply:

Wayne, The Leviton 3032-plr switch that you have described is for 120volt applications and will not work on a 240volt circuit.
A typical 240 volt air compressor requires two hots and a ground wire.
A neutral wire is not required.
A 120volt lighted control switch could be wired as an add on control circuit, however this would require a separate 120volt control circuit, a 120volt lighted switch, and a 120volt control relay with 240volt contacts rated for 30amps.
