What is this electrical breaker

[BeezFun]

My friend's well stopped working, he traced the problem to the 20A breaker in the attached photo. The 120v line power/neutral comes in to the top left and right screws. There are 2 screws at the bottom of the breaker, one feeding the well pump, the other feeding the sump pump in the well pit. One of those two screws no longer is hot, the other one is hot.
I've never seen a breaker like this, what is it called? I'm kind of surprised that a single 20A breaker can feed a well pump and a sump pump.

It's only 120V running the well pump?

Appears the White wire upper right is HOT also by the Black Tape?????

Yes, must be shallow

I don't think that is 120 volts and that definitely looks like someone didn't know what they were doing. I think they are running 120 v on the black and 120 v on the white with no neutral. You see the neutrals tied down with the grounds? Scary, but I have seen worse. Go look at the breaker feeding that and I bet it's a 220v breaker

OK thanks, I didn't see that black tape. You're right, this breaker is being fed by 220v and he lost a leg somewhere. I noticed the neutral wires bonded to the box too, this is a farm, so anything is possible. I'm going to head out there and help him. I was trying to diagnose this on the phone with a photo.

Thats normaly a fused disconnect. The fact that its powered by 240v is fine and that is a 240v breaker. It should not have two 120v circuits coming out of it.

In its place you can put a small sub pannel and run the circuits off that but i would only do this if the circuits cant be ran to the main breaker.

really? how do you think a MWBC is configured?, other then the neutral and ground being bonded, I'm not seeing a huge issue here.

Op thats a standard common trip breaker 240v.

Square D, 2 pole, 20 amp, 10,000 amp interrupting rating, probably Square D Type QO, if it plugs into stabs that are part of the back plate of the enclosure that the supply wires terminate on; or type QOB if it's bolt on (doesn't look bolt on), or maybe QOH if unit mounted.

The question is: Is the white wire (taped black) that lands on the lug at top right hot? As other suspect, seems it is suppose to be (i.e. 240V brought to enclosure). If it isn't, your problem is upstream of this breaker.

That's an understatement. I once worked on a grain bin fan, 120 volt that had one hot wire to it and a bare copper wire stuck in the dirt, it worked.
The farmer liked to have had a heart attacked when he got the bill from when I replaced the single THHN 14 gauge wire laying freely with 50' of new 10 gauge wire in conduit to it to make it all work and replaced the burnt penny under the burnt 5 amp fuse with a new 20 amp fuse. "well why did you replace all that wire, it worked before."
