I did a car park with bollards and lamp posts. Now this car park has a lot of woman drivers in so I RCD'd everthing you cannot be to careful. I have had to refix bollards countless times luckily they have not managed to run the lamp post over yet but give them time.There is a simple rule you can all follow when deciding if anything requires additional protection by RCD'S.Risk, and potential hazards.
In commercial and industrial installations you can reasonably assume that the equipment installed is monitored and controlled by trained personnel.
This is ok for inside the equipotential zone.
Anything outside that zone should be calculated and any extra risk for fire or personal injury or death should be accounted for.
Any fault on a metal lamp post, on a rainy day touched by a member of public would be a high risk, and unreasonable to assume disconnection.
Weather, fault conditions, and potential danger due to potential differences would make me err on the side of adding a RCD.
However potential differences would also dictate that should such a fault occur it would go right to ground and trip a mcb.
I love debates, its what I learn that makes me appreciate who I am.
I can not wait for Andy and Special Location to inform me.

I don't mind its late so I can get away with it.Admin 2 will not be amused, and Admin 1 will grass us out lol
Hello lillpete.....I am quoting for installing floodlights at a tennis club (for security not the courts )the wiring will be in plastic conduit so other than drilling straight through the walls no cables will be buried.
I have found that the old 3 phase Merlin board here is very expensive for RCBO's so provided the loops are low enough am I right in thinking that it's fine to have no RCD protection?? I'm sure it is but everybody's always banging on about RCD protection these days so I just want to make sure
No!!!!I think I just said that , Specs , but in one sentence
its very unlikely for there to be a case where post is live and fuse doesnt blow. although maybe more of a concern is many lights are fed from TNCS supply, but then the post is a good earth rod so would normally keep any possible voltage downThere is a simple rule you can all follow when deciding if anything requires additional protection by RCD'S.Risk, and potential hazards.

What Evans electric said.My interpretation of the Regs. is ...Commercial Premises , maintenance under the control of competent persons ... also surface conduit.. RCD not required.
