I have gotten some really good information from this web site. I have learned a lot from Mike Holt's videos. But I have never posted a question, but I am now.
I own a1930 something 4 unit multi family with 5 meters and five fuse boxes. And I have a few questions.
Does it meet code and is it safe to pick up the old non grounded nm circuits on new subpanels. If I have to replace the branch circuit wiring I would most likely use wire mold where I can't pull cable without removing wall coverings. The way I see many done around these parts is the mop board pulled off, Romex run behind it, receptacles mounted in the baseboard.
A local electrician did one subpanel for me. He snaked 100 amp cable up into the unit to a subpanel, and ran two runs of mc cable back down to the basement to pick up the two original circuits. He bugged the 100 amp into the old unused range circuit in the fuse box, protected by cartridge fuses. He also ran one or two new branch circuits from the new subpanel. The old fuse panels had rejection busman fuse trons installed and they were not conducting. I tested them myself. Power going in, no power coming out.
I question why run home runs back to the old fuse panel. If there are 2 existing circuits, why not just get cable to on of the receptacles, connect it there, and nut off the circuit in the basement that lead to the fuse box?
I am thinking about continuing the work myself. I would be retired if I didn't have these rentals and I want to improve them. I have some good experience. I worked with some really good electricians. But have never connected old ungrounded Romex to a new distribution panel. The main thing that gives me pause is liability. I understand I am liable forever on any wiring I do.
That's 3 questions
is it code to pick up the old circuits on a new subpanel?
is it safe ?
Is there any reason not to connect to any given circuit at the closest point to the sub panel?
Is the liability just not worth it.
