why would you need RCDs on street furniture? There all locked with lamppost keys and maintained by competent people?

 
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 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.

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 :D
Hello lillpete.....

The way to approach this sort of problem in the big red book is to suss out...

"Where the F*** is the part i need to read"

'FLIP!'.... you rude lot.... X(

bet you all thought I meant F**K.....? ]:)

ForK :DBlushing:^O:^O:^O

Anyway...

You Lillpete has got to select some equipment & erect it...

so.. this is wot points us all to Part 5 "Selection & erection Page 86 onward...

Part 5 has various chapters on particular bits such as wiring systems, Isolation, switching, Earthing... etc..

Then Chapter 55 "Other equipment" page 136 onward...

scan down that sub-index contents bit and low and behold A light from above shone down like a star over a stable.....

559 Luminaries & Lighting Installations Page 144 onward

now we are getting warm....! :p :D:)

and it even includes 559.3 Outdoor lighting installations

So you need to scan read pages 144 to 150 and try to find anything saying you need RCD's....

The reg 599.10.3.2 as point out by M107 (top 'o' page 148)

Refers to RCDs for lighting in Telephone Kiosks, Bus Shelters & Town Plans, (whatever they are!?)

not sure it applies to your stuff?

points you need to considerer are...

Are you using any Double or reinforced Insulated devices Reg 599.10.4 has some comments.

If the lights are less than 2.8m they should have a cover over the bulb 559.10.3.1 (iv)

There is NO need to bond adjacent metal structures such as fences...(559.10.3.1 (v))

AND

Don't forget.. Domestic external lighting wiring only gets into the RCD arena when it enter the building under plaster less than 50mm!

its only external sockets that HAVE to be RCD'd? :| ;) :x

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 down

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