I currently rent and the landlord won't touch the electrical. Currently, in the laundry room I have an old school 10-30 plug with two slanted and one "L" shaped prongs. I'm wanting to buy a Clipper Creek Level 2 24a plug-in unit, but this would involve using a 10-30 to 14-30 (they don't sell anything with the 10-30 anymore) adapter and a 25 ft extension cord to the EVSE unit in the garage. I've looked online, but most of the conversations involve going from 10-30 to 14-50. Does this sound safe and or feasible? Thanks for any help that can be offered, this forum is really useful.
