Hi, I ran into this awhile back. There are 3 tubes in the panel, each about 6 inches long, 1/2 inch dia. They are installed between the breaker lug and circuit. They appear to be a manufactured item but no labels seen. I'm a home inspector, not an electrician and have never seen this. Maybe some sort of choke coil or surge supressor? I was thinking fusable link but why on a breaker? Any help is appreciated.

Sorry, how do I get the photo on?

Nice pictures, I can enlarge em way up without getting too grainy.

These things look more like push rod tubes than anything that belongs in a breaker panel. Ya got what, four of them in there that I can see. I wonder what the condition of the wiring inside the tubes is.

One potential problem I see is the over bending of the cable/wiring at the end of the tubes. What keeps the tube ends from wearing / cutting into the insulation (besides the electrical tape)?

Another thing is that in a panel, pretty much all metal surfaces are either live or grounded. These tubes are an exception.


There are 10 types of people. Those who know binary, and those who don't.

That looks like one of the old underground splice kits where you poured a sealing compound into the tube after making the splice.

Why on earth would anybody want to use something like that inside a penel? [Linked Image]

I agree, it looks to be an underground splice. Maybe some one cut the wire too short?

If thats the case, it kind of over-kill for the application, when a wire nut will do the same.

Actually the wires aren't too short, on second look.

What are they?

Its interesting what wires they are connected to: one pole of a 2 pole 30A, one pole of another 2 pole 30A, and a single pole 20A.

I cant think of a single legal application where you would have this on a single pole of a 2 pole breaker.

BTW, are those white wires landing on the breakers, or is the sun just washing out the color?
