Hi, I just ran into a similar this issue at my new home. When plugging my Tesla portable charger into a 240v 10-30R dryer outlet that was added by the previous owner, it works fine overnight unless someone uses the microwave or is in the fridge too long for the compressor to kick in. I can actually reproduce the issue whenever I want by microwaving a cup of water after plugging in the charger and car.
I took a peek into the outlet box and noticed they used 4wire #10 with the hot going to the blades and the neutral going to the middle. The ground is wired to the outlet box. I followed the wire back to the panel and it's on a 30Amp ge breaker circuit switch with the white neutral is on a bar down the right side and the ground is on a bar down the left.
From reading here I wonder if the box is wired incorrectly and if the ground should have been connected to the middle of the plug and the neutral should have been left in the back of the box. any thoughts on this?
