I have a freestanding half-wall in our garage. It’s constructed of 2x4s and finished with drywall and is in a big L shape. It’s technically mobile but heavy and doesn’t move easily. I want to get more outlets in this wall for different chargers, a compressor, etc… I could get a large surge protector bar and mount it on the wall and connect it to a regular outlet but I was thinking that actual receptacles would give me more flexibility to design the space as I see fit.
So my question is the following: Can I install several receptacles along this wall, connected to each other through Romex but not connected to the house’s electric panel? They would be powered by plugging an extension chord into one of the outlets (or using a hardwire conversion kit like they sell for garbage disposals. Is this against code or otherwise a terrible idea?
