Installing a Separate Pump Circuit Breaker Panel
Wiring Circuits and Circuit Breakers – A look at common 120 volt and 240 volt house wiring circuits and the circuit breakers that are installed identifying the types and amperage sizes used in most homes and electrical panels.
Electrical Code Issues Concerning Propriety Service Conductors
Electrical Question: I added a 40 amp 230/115 vac meter panel to split the load to the well pump from the rest of a rental house on it’s 100 amp overhead service. Both panels are now fed with a hot gutter. The conductors to the pump run in conduit from the new service disconnect to an 886RT can mounted below, then under the house and out the back, underground to the pump. Some of the conductors from the existing combination meter panel also run in conduit to the same enclosure, then under the house and on to various household loads. The job has been inspected and connected. Now a question has arisen about the propriety of the conductors from different service disconnects entering the same enclosure. Frankly I was more concerned about the conductors running under the house, but I couldn’t find any directly related issues in the code book.
I’m still researching, but I think some of you might know.
Thanks for checking this out. Mike.

Wiring a Switch for an Air CompressorWayne 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.
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.
