I brought home my new Model 3 today, and will be using 110V for charging until I have an electrician install a NEMA 14-50. I started charging at 12 amps, but it stopped after a few minutes. I lowered the current to 8 amps and it still cuts out. The status lights on the mobile connector are still rotating, but there is no light on at the charge port and no charging occurring. If I push the button on the handle, charging resumes for a few minutes. What would this problem be? If anyone has a recommendation for an electrician on the SF Bay Area / East Bay / Contra Costa area that would be appreciated as well.
