Receptables,outlet grounding

[bradfordservicesinc]

I inspected a new home and none of the wall switches or receptacle have the grounding wire connected to them. The ground wires are connected and just past through the box. The switches and the receptacle all have the green grounding screw. Where does the NEC address this?
Also how close to the edge of a bathtub can wall switches be located?

250.126,
As close as they want, just so long as they aren't inside the tub.

I don't understand what you mean here. Connected to what? And just to make sure we are speaking the same language, what you mean by "the ground wires"? If you can describe all wires coming into and out of the box, then I might be able to help you determine whether they are installed properly.

I hope this helps.
250.138 Cord-and-Plug-Connected Equipment.
Non?current-carrying metal parts of cord-and-plug-connected equipment, if grounded, shall be grounded by one of the methods in 250.138(A) or (B).
(A) By Means of an Equipment Grounding Conductor. By means of an equipment grounding conductor run with the power supply conductors in a cable assembly or flexible cord properly terminated in a grounding-type attachment plug with one fixed grounding contact.
406.3 General Installation Requirements.
(B) To Be Grounded. Receptacles and cord connectors that have grounding contacts shall have those contacts effectively grounded.
404.9 Provisions for General-Use Snap Switches.
(B) Grounding. Snap switches, including dimmer and similar control switches, shall be effectively grounded and shall provide a means to ground metal faceplates, whether or not a metal faceplate is installed. Snap switches shall be considered effectively grounded if either of the following conditions is met.
(1) The switch is mounted with metal screws to a metal box or to a nonmetallic box with integral means for grounding devices.
(2) An equipment grounding conductor or equipment bonding jumper is connected to an equipment grounding termination of the snap switch.

I need to clarity my question. There is a ground conductor on all the wiring to and out of the switch and receptacle boxes. These are non metallic boxes. The ground conductors are wired together and with no connection to the switch or the receptacle.

You have to ground your switches and recp's.

Re: Receptables,outlet grounding

The term "ground conductor" is not defined in the NEC and I'm not sure what conductor that you are asking about. Is it the white (grounded) conductor or the bare (equipment grounding) conductor? To get meaningful answers, you must use the correct terms.

Re: Receptables,outlet grounding

I will try again. It is the bare grounding conductor and not the white grounded.I hope this clear it up.I always have tied the bare gounnding conductor to the swith/or recepacle or/ to the yoke.I would normally see this but the one electrican seems to do things different from others so I want to know if this is Code or just good building pratice.

Re: Receptables,outlet grounding

The purpose of the bare equipment bonding(grounding) conductor is to connect all non-current-carrying metal parts of enclosures for conductors and equipment, including cord-connected equipment, back to the grounded conductor of the supply.

This is required so that the OCPD will operate to disconnect the circuit in the event of a hot-to-enclosure fault.

Do you think the installation you described is code compliant?

Re: Receptables,outlet grounding

Just a note:
I agree with Don and Charlie. Ground wire is not a term that is defined in the NEC. Yes I agree art 250 grounding is confusing, but art 250 has specific terms, and the trade has other terms.

I suspect what is being questioned here is the "equpment grounding conductor".

Re: Receptables,outlet grounding

Per your discription, if you plugged a receptacle analyzer into a receptacle you will show an open ground, is this the case?

Re: Receptables,outlet grounding

If I understand this correctly, the equipment grounding conductor is bonded to the box, but not to the devices in the box?

If the receptacles are of the "self-grounding" type, then this might be compliant with 250.146(B):

Contact devices or yokes designed and listed for the purpose shall be permitted in conjuction with the supporting screws to establish the grounding circuit between the device yoke and flush-type boxes.

And the switches may be covered by 404.9(B)(1):

The switch is mounted with metal screws to a metal box or to a nonmetallic box with integral means for grounding devices.

Re: Receptables,outlet grounding

From what I understand this is a violation and you need to have a bonding jumper to your devices to ensure a grounding path from you devices.

bradfordservicesinc:

I know exactly what you are saying, but frankly if you need to ask this question should you be inspecting other peoples work? This is a no brainer.

For starters see 250.146.

May I also suggest that you buy a copy of the
NEC Handbook.

An inspector that does not know the code is very annoying and can cost electricians a lot of money with miss interpretations and the time it takes to argue with them.
