I currently have an electric range.. changing to gas ....the question is....
the current electric line is 220 60amp
The gas range needs a 110 plug in
Can I change the 220 line to a 110?
I would look at running new wire. Leave the 60-amp wiring in place, just in case you decide someday to go back to an electric stove.
If the 220 wiring includes a neutral (it might not), then there's no reason why you couldn't use that neutral and one leg of the 220.
