I have to add (3) 10 breakers to an existing control panel. There is enough capacity in regards to the main MCCB. I don't have any room on the distribution block..
Can I jumper off the line side of other CB's? The row I will be adding the 3 additional breakers already has multiple CB's the same size.. I'm just unsure of the amperage capacity on the wire once I start jumpering.
There are (3) 14 AWG feeding the CB's from the distribution block, If I jumper from that CB to another then another then another... wouldn't that overload the wire amperage capacity since it would be carrying current from 4 different loads after the CB?
Do I need to size the wire for the FL of all loads when using jumpers in this manner?
