grounding questions


Ok, I am installing a new 200amp service. I have a meter socket without a disconnect. I have a GE 200 amp 32 space panel. I get confused with the way to ground the system. Let me know if this is right. I run my 2 hots and neutral from power co to meter socket. Then the same wires plus an insulated ground to the breaker box. Then a bare ground from ground side of panel to the ground rods? The neutral and ground bars are tied together at the bottom with metal. That should stay right? I have only done a few of these so far and every panel has looked different.

Man I'm glad the word "fire" is in your name. :-) If you're not sure how to set this up I don't think I'd be doing the service main install. I'm not saying you're design is right or wrong, just that a 200A main isn't the place to play if you're not sure yourself.

This is the kind of job you hire somebody for who knows what they're doing, like a licensed electrician.

After looking around I guess I just have to come from the ground bar in the panel to the ground rods. The panel is the first disconnect, so I think I am thinking right at the moment

grounding questions


you do not run 4 conductors from the meter to the panel.

With a GE panel, there is "bonding" screw that comes with the panel. It screws through the neutral bar and becomes your main bonding jumper (neutral to ground connection). The neutral and ground bars, if both are isolated, have to be bonded to each other. Your GEC will run from your neutral or ground bar to the grounding electrodes. The size is determined by the type of grounding electrode being used and the service size.

I'm betting the bars you are referring to as grounding bar and neutral bar are actually just 2 neutral bars. If I remember correctly, GE uses dual neutral bars in the manner you describe. The grounding bar is often a separately installed bar that attaches the the panel tub.

Provide the panel model number and it can be checked.

Now, you have actually shown your lack of experience in electrical work so please don't go and kill yourself by playing with things you really shouldn't be working with.

You have the potential to damage equipment, miswire, cause damage to your house or KILL yourself.....get someone who has an understanding of code, and how to install a service......I bet a few bucks there are other problems wrong with your panel install.

I can relate to your desire to do things yourself, but this is one of those times when you should hire a professional.
