Grounding a Panel and Meter Box
Asked Jan 7, 2008, 11:20 PM
I am installing 200 amp electrical service in a new residence using 2/0 SE cable. The main breakers are in the panel. Since it is a GE panel, I have added grounding bars which did not come installed in the panel. The neutrals will all go to the neutral bars and the grounds to the grounding bars. I will also need to use a bonding screw to bond the neutral bars to the panel.
Should the #4 ground wire for the panel be attached to the neutral or grounding bar?
Other than the obvious connection through the metal panel cabinet, should there also be a bonding jumper between the neutral bars and the grounding bars?
Should the #4 grounding wire also be bonded to the meter box (which does not have an existing ground wire lug or screw) on its way to my ground rods? If so, what is the best way to do this?
