Grounding

[Alwayslearningelec]

I have one FACP and it ssays to run (1)#8 to water main pipe(on street side). I know you sometimes ground to the water main with a clamp but what does street side mean. Where it enters the building and then on the outside? THanks.

Sorry!!!Does it have to be in conduit? Could it be a bare conductor? Thanks.

I believe the reference to street side means on the supply side of the meter.

Does this grounding conductor establish a solid connection with the panel's EGC?

What model/brand is this panel?

Thanks. Can't tell.

Thanks. Can't tell.

As far as I can tell, installation of this grounding conductor doesn't fall under the NEC other than being a manufacturer's installation requirement. If it is under the NEC, I cannot ascertain what type of grounding conductor it is to correctly apply NEC requirements.

I appreciate the help.

Sounds like this is a NYC requirement. From what I remember the ground has to be in rigid conduit. Good luck trying to find out why it's required.

hmy: thanks

This actually sounds like the very reason that we are now required to have auxilliary grounding terminals on the outside of our service panels- so that things like this control panel have a place to run terminate their ground wires.

I'd downplay the instructions to ground to the water main; sure, you're also required for the water main to be one of your 'grounding electrodes,' but I would allow you to connect to anything in the 'grounding network.' What I would not allow is the -far too common- practice of the low voltage guy banging in his little, independent, ground rod. After all, ALL electrodes must be bonded together.

You know what, I actually saw a grounding drawing that had "ground studs" placed around the switchgear. Is this what you mean by ground terminals? What are thesse exactly?

no, I think he's referring to a device that clamps on the grounding electrode conductor or any part of the grounding electrode system that would provide terminals for other systems to be connected to ground
