Ground Wire and Plastic Boxes

For a basement-remodeling job I'm using plastic outlet boxes (five of them). Does it meet code to connect the ground wires together without running a pigtail to the receptacle? If this is not code, please tell me why.

Thanks in advance

No, it does not meet code. It does not meet code because it leaves the receptacle ungrounded.

Why would you want to do such a thing? It makes no sense.

NEC Art 406.3 reads-----"Receptacles installed on 15 & 20 amp. circuits shall be of the Grounding type.----Receptacles (with) Grounding contacts shall have those contacts effectively Grounded.--the Grounding contacts of receptacles shall be Grounded by connection to the Equiptment Grounding Conductor."------Art 250.148 reads-----"Equiptment Grounding Conductors shall be spliced within the box with devices suitable for the purpose. Grounding connections shall be such that the dis-connection of a receptacle does not interrupt the Grounding continuity."

I think mchrist meant pigtailing the ground wire to the receptacle box since the post made a point of noting the plastic boxes. Whether plastic boxes are okay depends on the exposure. If used correctly the box would not need to be connected to the ground. The receptacle alway gets grounded.

The green screw on a receptacle is listed for only one conductor. This is the reason for installing a pigtail instead of both bare wires to that green screw.

Hope this helps

You can also use what is called a 'greenie'. It's a green wire nut with a hole in the top. You leave one of the wires long and the put it out the top and screw down the wire nut to tie the grounds together.
