I'm building a shed that will be housing a washer, dryer, hot water heater, and a freezer. The dryer and water heater both require 220V 30A and will be used concurrently. The washer and freezer use 120V 15A connections (not sure how much they actually draw), the freezer will run continuously. I'd also like a light fixture and a 3rd 120V outlet.
The main is 200A service. I have an existing subpanel (100A) that supplies my camper.
For the shed, I'm considering another 100A subpanel. The shed is 30 feet away from the main, and I'm going to bury the cable underground (with or without pvc conduit depending on recommendations here.)
Is 100A sufficient? Or overkill? What wire size would I need from the main panel to the subpanel?
I think I need to run 4 wires (two hot, a neutral, and an equipment ground). Is this correct?
