Default Oxide inhibitor on buss bar.

How do you guys feel about using an oxide inhibitor when installing circuit breakers? Almost all buss bars are Aluminum and sometime the breakers are hard to install or remove because of the cheap quality of the newer equipment, both breakers and panels. I know some breakers come with some type of grease but some do not.

I've done it before when it felt like the connection was galling up, that feeling you get when it seems to take excessive force to seat or remove a breaker, like the metals are dragging against each other a bit too much.

This is something that seems like a good idea but I hesitate to do it unless the instructions allow for it. It will probably help with oxidization, but does the reduced friction of the grease cause other problems?

Most breakers come with a little dab of electrical grease (name escapes me right now); we have a tub of it for MCC rebuilds.

I think if you are removing / reworking breakers in a panel, it would not hurt; but the key is not to use too much. You only need a very thin film. I also consider it if I use a new breaker that has been bouncing around the truck for the bit or sitting on the shelf at the shop.

Edit:here is the stuff that we use https://www.sanchem.com/electrical-c...lubricant.html

Cheers
John

I've seen where guys put no-alox brand on breaker stabs and then it hardened up like candy over a period of time.

There is good info on here about the procedure. Use the search function and you might be able to find it. I say might. They had the exact gel catalog number the manufacturer's use on the stabs at the factory.

They don't seem to sell direct on site, you have to request a quote.

Do you know if they sell small quantities ?

I know you can get in small tubes, but if you are using it right a small tub / tin will last a very long time.

Unfortunately I bought it a long time ago; I don't remember from where or who. Could have even been e-bay or even at an auction as part of a mixed box of supplies or something... small tub has lasted probably 10 years anyway.

If you want to come to Niagara for a beer, I will give you a little film case full if you want!

Cheers

Oxy ban in a good close second to that stuff. I get it at Graybar. Looks the same, silicon based. Works terrific on car battery terminals as well.

Just hate seeing No-Alox being used on breaker stabs for the reason I mentioned earlier. I can't say for sure if it causes more problems than it helps, but I bet it does. Otherwise it is ok for wire to lug connections. And messy.

I use the Ilsac or whatever it is called no ox on breakers instead of the ideal stuff because it doesn’t separate. I also pull the screws out of lugs and put a dab on them also. Seen to many breakers fail on the stabs in outdoor panels.

The Nolox and the No-Ox-ID are two different items. I don't think I would put Nolox on a buss, but would put No-Ox-ID without even thinking about it.

On bus bar use electrical joint compound. Same as no-Alox but no-Alox comes in two versions. One has zinc oxide particles that are an insulator and the other doesn’t.

Buss makes fuses. Bus is the term for a part designed to carry current.

It seems the dab the manufacturers put on the breaker is enough, but I see no need to add more or put it on breakers that don't have it already. If there's some empirical evidence that panels are failing without it, I'll change my mind.
