Old Loadcenter

[JDM1457]

What is the purpose of the square piece of bakelight screwed to the right side bus of an approx. 50 year old GE 42 circuit residential load center? Other than preventing the installation of a 1pole CB? I have never seen this before.

Do you have a photo?

Possibly a way to keep from installing tandem breakers? If they were even available in GE 50!years ago.

But why just one in a 40 circuit panel? Or, I'm thinking maybe to limit the number of 2 pole spaces?

Does it only cover the upper right two slots? On some GE panels if you use a backfeed breaker as the main it installs in the top left two slots and the hold down clamp is a piece of plastic that mounts in the upper right two slots. Could it be that? I'm not sure if that's true for 50 year old panels.

no, it it only on one 1 pole space about half way down on the right side.

It’s clearly put there to prevent the installation of a 1pole CB, but for what purpose? And there is no indication on the panel diagram on the cover that shows this piece.it shows all 40 spaces as available.just curious as I have been doingthis a long time and I’ve never seen this before.

GE doesn't have tandems. They do have the 1/2 width breakers the bus design is the rejection feature, if a slot wasn't intended to accept one those breakers it won't have the tabs to match up to the breaker connection jaws. There were no non CTL breakers to cheat with in this series.

I know what you mean and this is not that. This was actually screwed on the buss. the screw appears to be 10-24 thread.
