Mar 5, 2012 · Try it. The splitting you expect just doesn't happen. The stripped wire should be long enough that it extends past the screw a little bit, so the screw isn't bearing on the very end of the wire. The screws are sized so they take up most of the hole and they don't pierce the stranded wire, they just flatten it and jam the strands together.

Apr 21, 2022 · Some contractor damaged the underground utility feed to my duplex. We have 2 units with a 100A breaker each and 2 separate meters. Right now they have 3 Aluminum conductors 2 AWG running in a plastic

Aug 18, 2020 · This is a 125A panel. From the labeling on your panel, in particular the note about field upgrading 100A mains to 125A by replacing the main breaker and the meter-to-main-breaker wire jumpers, we can tell that this panel has 125A busbars in it, since UL wouldn't have permitted the manufacturer to provide such an upgrade as an option otherwise.

You can just use whichever bus is easier to get to in the main panel since they are wired together, either with a large wire, or they can be physically the same piece of metal. That being said, any electrician who take pride in their work will make sure that all of the neutrals run to one bus-bar, and the grounds the other.

Consider the following: you have a 3 wire feed, bonded N-G at sub panel, and a water pipe connecting 2 structures. The neutral wire somehow gets severed. Current would flow from the hot to the load to the sub panel neutral bar, then jump to the sub panel ground bar, then to the water pipe, then to the main house, to the main panel ground bar ...

If you need an additional bus bar, that's an easy connection, just use a large gauge wire (such as 4ga) between the added bus bar and the current one. You don't mention ground wires, but if you added a bus bar, it might be possible to move the current grounds to the new bus bar, bonded to the panel and the existing neutral bus bar.

Jun 24, 2019 · The issue is that most panel busses aren’t rated to have more than one wire per termination point. Some are but most aren’t. The issue, other than just the question of certification, is that they may just not be designed to hold two wires …

This isn't really an option for me though, since the 17 neutrals would leave only 6 screw terminals left to connect up all 17 grounds. Even if I used wire nuts to combine multiple grounds together before going to the terminals, this still seems excessive. At the very least it would be pretty messy. Can I install an additional ground bus bar?

One thing they did wrong is they ran two separate 120v circuits through a 10/3 wire intended for a single 240v circuit, and used the same neutral. The insulation was stripped off the wires in the conduit, which is why the wires appear separate where they come in the box.

Oct 27, 2017 · if you want to troubleshoot a ground fault, you can remove the neutral-ground bond, and replace it with a wire which you loop 10 times and clamp an ammeter around the loop. Now the meter indicates ground leakage at 10x resolution. It'll take you literally 30 seconds of snapping off breakers before you find which breaker it is. That was easy.
