Can i use the steel?

[Jas0n7]

Hey Guys,

I'm wiring a warehouse at the moment. I have the mains panels in one corner of the building. out of the mccb panel i have bonded the structural steel with a 25mm earth, bolted, lugged, labled everything.

Now heres my question, all the services come in the other end of the warehouse. instead of running a 10mm earth from one end of the building to the other cant i bolt, lug and lable a 10mm cable to the steel near where the water comes into the building and then earth clamp it to the water main?

I'm 99% sure you are able to do this but i can't find it in the regs book anywhere?

Please help!

Paul, I think wirepuller was referring to the "Is it possible to give them their own earth rod?" part of your post, that would certainly not comply with the reg's and would introduce different potentials on metalwork along with the dangers that that would present.

The lightning protection system is risk management and I haven't seen a single documented case of injury while in contact with a tape, can you imagine the odds of it happening?

Thanks for the answer, its just that I've got to go out of the pub for a cig now and it was one of those silly thoughts. The rod idea, didn't think before opening my mouth so to say. Hope the regs I quoted were useful, I'll stick to what I know and stop asking stupid questions. (until next time) ps, dose an electric fence have a fuse?

Don't stop asking questions!

As for the lightning question, I think you'll have a far greater chance of death from the ciggy!
