I'm looking for some advice on installing a L2 charger at employer-provides housing. I am paying to have a 240 line installed ($650), and would prefer to use a plug in lieu of hardwire given that it's not my home, so my thinkng is that it would be easier, when my contract is over, to unplug the unit and take it with me. There seems to be several different types of 240 plugs? Not sure if it makes a difference? This is a 5-year timeframe with the housing (although could be longer if my contract renews), so is my thinking right on the plug versus hardwire? It would be installed outside on the wall of the house. Any advice/recs would be appreciated.
