Can anyone tell me what these are?

So the new electric shower is in, but I discovered two wee copper washers with two tabs sticking up on each that haven't been used.

What are they? Should they be on somewhere? I'm just being nosey really

Often used to connect the earth conductor of the cable to an earthing point on the frame of the shower. Washers keep the conductors from squashing out as the nut is tightened

Look like terminal washers for the live and neutral connections.

Is that instead of using a crimp terminal on the earth then?

sometimes a crimp lug will still fit inside of them, its usually best to keep them as it increases the area the cable or lug sits on as well as the area the nut tightens on, you often see two on one terminal, opposing each other, or just one with a plain washer, usually on a bare copper earth post, as said

Thanks all. Was just curious - you know when there are bits left over haha

They ought to be gainfully employed.

I thought it would be quick and easy to googl picture! It's not! I would prefer to see these used.

 

[DaveHerns]

So can we assume he used crimps?

We shouldn't assume, but it would be nice to know if he did!
