I've had the moment to work on 440 volt roof top heating and AC.
Once in a while, need some power to run a 120 volt device. Is it 120
volts from one leg to ground?
(Yeah, I could just check it. But I was on the roof yesterday, and not
sure how long until I get to another roof.)
There is normally a transformer in the panel to give you 120 volts if
120 volts is needed there. Don't you have a meter?

I haven't spoken to my wife in 18 months.
I don't like to interrupt her.
