Removing a Medicine Cabinet Light Installing a New Fixture

How to Install a Wall Fixture Electrical Junction Box – If the light fixture is a bar type then a larger junction box can be installed off center if the fixture will allow a hole to be drilled in line with the wall box for the wiring to pass through into the wall box for the connections.

Installing a Wall Fixture Electrical Junction Box
Electrical Question: I am trying to replace and old bathroom lighting fixture which is attached to a medicine cabinet.

It seems I may have to look for a different fixture with fewer wires.
Thanks!

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.
