I want to tap off one 120v leg of my water well wiring to put in a 120v receptacle at the water well pressure switch.
My water well is a sub pump, running off 240v single ph.
Powered by 2 lines of 120v each and one ground wire brought in via conduit. There was no neutral wire run.
The power is supplied off a disconnect on the side of my house, which is fed directly from a breaker in the main panel of my house--the main is 'first means of disconnect' which means neutral and ground bus are tied together per code in that main dist panel.
Water well switch is wired just like the one below:
(All I want to run off the receptacle is a 100W light bulb)
If I tap off from locations A & B, (from 1 hot and the ground lug) it will give me 120V ac, but will this be safe?
