220v to 110v

I am putting in a new irrigation system. I have 220v running
to the well house, where I need a 110v outlet for my Timer.
I was told I could pull 110v out of the 220v conection on the well. Is this true?? If it is, How do you do it???

You cannot pull 120 off a 240 feed.

You can (depending on the loads involved) pull 120 off a 120/240 feed.

The only way you can run 120 volt off the 240 volt line is if you have full 4 wires [ HOT , HOT , NETRUAL ,GROUND ]

typically wire colour is Black , Red , White , Green or Bare wire depending on what kind wire you have there.

the safest way to do this is run a small subfeed box and have correct breaker for pump and the timer as well

if need more question just ask us here we will try to help ya

Merci, Marc
