I am rewiring my basement that has originally been set up as a basement suit and trying to isolate the basement from the upstairs panel. The house was built in the 70s and has had the service upgraded to two 100A panels some time ago. The panel for the upstairs has the main panel in the basement and then the sub panel on the upper floor. This sub is fairly old and has no ground bar to isolate the neutral from ground which is a code requirement. Has anyone else run across this with any ideas to help?
Yes thatís correct, 2 panels in the basement that both have there own meter (one for the basement suit and one for the upstairs) and plus one sub panel for upstairs as well. The main feed is a 3c with ground. I was thinking about the ground bar idea but as soon as I start changing things in this panel then I will have to get this inspected as well. My plan was to only change wiring in the basement and only pull a permit for this basement reno.
Thank you for this idea as well for the metering options Tesla. I will save this site for future jobs. In my case it is just a matter of separating the two panels and then the basement suit will have its own meter.
