Long story short, electrician repaired double-lugged neutrals, he tells the homeowner that he double-lugged them intentionally because he couldn’t get the proper torque with a single wire. He also said that he believed it was “against code” to do it this way but he felt safer than leaving improperly torqued. He then proceeds to tell the owner that he is no longer responsible for any damages since the inspector (me, ha ha) said to change it.
Ok …now the problem… besides the electrician thinking I am responsible for any problems, the panel now hums and the owner is very concerned. Is it possible that it hums because there is not a solid connection at the neutral lugs. The owner swears it did not do this before the electrician came out. I have not been back to see or hear what is going on but I will this weekend.
p.s. It is a Siemens distribution panel located in laundry room, air handler and water heater in same room.
All “feedback” is welcomed!!
Thanks in advance!
