On one leg or two legs?


If you install two dedication circuits, would you install both breakers on the same leg or one on each? and why?

I would suggest running isolated ground circuits. Each circuit has it's own ground run back to the panel to a separate ground bar. Then the Isolated ground bar has it's own ground run to it's own ground rod. If you are running two circuits, I think it would be worth the small added expense. I am not an electrician, but I play one on tv... nah, but my friend is, and we just did this, and I don't think it would matter if they are on different legs as the voltage is determined from the service wires. but if you have room on the panel, just use the same leg? If you have a meter you can check the voltage.
Hi Ghstudio, Sorry, I may have things a bit mixed up, but the all the ground rods are tied together. My friend Jon is a master electrician, and everything passed inspection. I had originally asked him about hospital grade receptacles and told him what I wanted to do. He suggested an Isolated ground circuit as they are what he installs for the most sensitive, both voltage and ground sensitive, computer equipment, he has done work in hospitals too but told me for what I wanted, an Isolated ground would be best. I would think that if each receptacle has it's own run via a 12/3 wire , all the way back to the panel on a separate ground bar in the panel, that there couldn't be any ground loops. I think the ground pin in the receptacle runs back to the panel, and the receptacle itself is grounded to the metal box. It sure made a difference sound wise too.
