cost of adding 220 line
220 volts, but it won't be any cheaper to put in if you need it later. Talk to the electrician about putting in the 220 line for $325.00 and adding a subpanel in the garage with the aforementioned 20 amp 120 volt circuits coming from the subpanel.e'll probably need to add another circuit at the panel (if you have open slots it will be much cheaper), assume 100' of 10 gauge wire, cut a hole in the sheetrock, fish the wire from the crawlspace to the hole in the sheetrock, insert a drop-in box, wire up the outlet and hand you the invoice.
