My company recently switched circuit breaker vendors.

Our old vendor allowed us to jumper on either the line or the load side, but our new vendor only allows the installation of a jumper bar on the load side.

I have only seen jumper bars on the line side of a circuit breaker.

Does anyone out there jumper their circuit breakers on the load side?
Is there any reason to do it this way or not to do it this way?

 

I'm not sure what you mean by jumpering.

 

>I'm not sure what you mean by jumpering.

I should have mentioned that these are Miniature Molded Case Circuit Breakers that would go on industrial control panels. I should have been more clear. I'm not talking about house wiring.

If you were jumpering 2 circuit breakers on the line side, then the line side of each circuit breaker would be connected together. In this case, I'm using a jumper bar. The jumper bars are pieces of copper designed to fit into the circuit breakers.

I'm referring to jumpering as electrically connecting 2 points together. If you measured the resistance between 2 points jumpered together, you would get <1 Ohm (preferably ~0.1 Ohm).

 

I can see the utility in jumpering the line side, but not the load side.
