stranded wire gauge 2 in neutral/ground bus

amakarevic

Is it OK to separate only 1-2 of the about 6 stranded individual threads for fitting into a small hole in the neutral and ground bus bars because all of them won't fit?

or are there adapters you can get that fit in where the screw goes but the hole is bigger to receive a fatter wire (my guts tell me this is the solution)?

This is for a 100A subpanel

Thanks

There is a terminal made for it and it has to be used.

look at the panel specs, every item available is listed for each panel.

You need something like this, but... it MUST be listed for type of conductor you are landing, grounded, or grounding type conductor.

i am using gauge 2 AL cable with 2 hots, 1 neutral and a ground. the ground is skinnier than the rest. i checked and AL is OK in my municipality for feeding a subpanel. some old cables in the house, probably from before WW2, are also AL

The problem is, the lug I posted us usually only good for a grounding conductor....

I have to ask, are you ever going to finish this reno. I just went back and took a look at the threads you've started. You've been installing panels and building appartments since 2008. You do know this site is for diy right. Not DIY handyman for other people. No offense intended if it actually is for your own use, but I for one don't aprreciate being someone's sounding board that's doing electrical work for other people illegally if that happens to be the case.

As I said no offense intended. You took on a big project then. I think ill stick around and read your posts still. I'm curious as to if that panel in the half wall passes inspection.

Best of luck with your reno.

If they are that old, they are probably NOT aluminum. More likely they are tinned copper.

I got this at HD but it's called "neutral lug kit" even though it looks like there is no reason you couldn't fit ground in it too.

Thats only rated for 70 amps!

I don't get it. There should be a hole in the ground bar large enough to accept the wire. Usually its on the top of the bar and feeds a different direction. Same with the neutral bar. It should have a larger lug on the top too. Is like to see a pic of the guts of the panel if possible. Somethings not adding up. You shouldn't have to buy anything.

there is only one big one and that is for the incoming wire. but on the main panel you have an incoming big wire from the meter (not sure what gauge but certainly fat) and then there is a big out wire for the subpanel, gauge 2. applies both for neutral AND ground. so i do need two fat adapters rated for 100A.

try this out, it screws into the existing screw hole. most likely ul listed if it's sold at sears.
