Bonding Conduit

[jawbox]

Hi,

I have a couple of questions regarding bonding/grounding.

1) The sketch below leads you to believe that the bonding jumper has to be a separate wire, is this the case or can you attach the grounding conductor to the bushing and then into the conduit?

Here's an example I saw walking one of the houses we built. The grounding conductor attaches to the bonding conector at the end of the emt and then connects to the incoming water service.

2) If you connect your meter base to the service panel with rigid conduit does it need to be bonded on both sides (meter base and service panel)?

Thanks

The sketch is just explaining that if you use another wire for the jumper it must be at least the same size or larger than the GEC, it is perfectly fine to use the GEC through the bond bushing lug.

Perfectly fine

It only needs to be bonded on one side and this doesn't necessarily mean a bonding bushing must be used on the one side.

You can either run a bonding jumper or loop the GEC through the bonding clamp.

The installation in the picture that you provided would be fine.

Service equipment needs to be bonded in accordance with 250.92.

Looks like Roger beat me too it.

I agree with Roger.

If you're planning on looping, a "lay in" lug is your best friend
