Is there any way to get 120V from 240V 12-2?
I have a potential buyer for my summer cottage who would like to use heat tape on the pump plumbing in order to extend the useable season into the early winter (for hunting). My well pump is in a 10-foot deep pit and the wiring to it is direct-burial 12-2wg carrying 240V to the pump. This wire was buried a long time ago and now there's an attached garage, a driveway, a deck and a sidewalk over it.
With no neutral I can't see a way to advise him how to proceed.
Not a deal breaker--I just want to help if I can.

No no way short of a transformer and only if there is enough excess amperage. Simpler to just use 240 volt heat tape. Just Googled and a lot of hits. Example: EASYHEAT HB Series Pipe Heating System

Hmmm--didn't know you could get 240V heat tape. That would be best. Other than that I may check the motor rating & see if it (plus the heat tape) can be run off 120V 20A that the cable can carry. I changed the breaker to a dual when I replaced the pump so the motor would spin up faster without dimming the lights.
Or I could do nothing
I have a feeling since I'm just a block away he'll be coming to me with any questions.

I just had to ask this and yes, I know this is off topic.
