Which bonding method proper???

Nestor

I live in Ontario. I'm wiring a cct of outlets and can't seem to decide which is the proper method. A "CEC simplified" book states that a pigtail is required from the receptacle to the incoming and outgoing ground.

My single gang boxes have two bonding screws.

Is the following within code:

1. First ground terminated at one bond screw.
2. Second ground wrapped around second bond screw and terminated at ground lug of receptacle.

10-808(2) of CEC does not mention pigtails, but does state that "the arrangement shall be such that the disconnection or removal of a receptacle, fixture, or other device fed from the box will not interfere with, or interrupt, the bonding continuity."

It would seem the above method will allow removal of receptacle without disrupting the bonding continuity.

I do know that only one ground conductor per bond screw. If not, then I can't understand the purpose of the second bond screw in a single gang box.

Help!

I do this way all the time and no inspector has turned it down. You could also put one under the ground screw and then marrete them and make a pigtail to go to the ground on your plug. I don't like this because you are adding another marrete and it makes your box look more messy.

Thanks for your reply!

That was my thoughts too. It didn't seem to make sense to add another marrette.
