My super asked me to replace some 30 year old nm for a customer.
Upon entering the residence, everything was functioning but they wanted it to look more professional. I planned to replace with a couple of whips.
The wiring is for a Square D 30/50 pump. It’s fed by two 20a (in tandem) at the panel. Here’s where things get wonky:
-One 12/2 hits a switch near the pump , which feeds to the left side of the Square D. Standard disconnect it appears
-The other 12/2 goes directly from the panel and into the right side of the Square D. I’ve never been able to detect voltage on this side AT ALL
My question: is this a common way to wire a well pump? Not understanding why it was done in this manner.
Journeyman residential electrician, and this is the first one I’ve come across
thanks
