Does it make a difference which neutral bar that I use?
My 200A QO entrance panel has two ground/neutral bars, one on each side next to each 120V leg breaker stack. Most of the branches enter the left side but four of them for lack of available breakers on the left leg are landed on right leg breakers. My question is are both ground/neutral bars strapped? In order to make the box neater and shorten the wires may I land grounds and neutrals on unused taps on the left ground/neutral bar even though the hot is on the right leg? If the bars are just bonded to the panel but not strapped to each other I am concerned about putting potential on the box. I would think the bars must be strapped to handle unbalanced 240V loads though.
Thanks for your help, Jim
