Rcd outdoor skt.

[gregorabbott]

Hi guys quick question. Neighbour wants outdoor skt at garden shed. Her house has no rcd protection. Old rewirable fuse board. Cable to be buried underground. Going to spur off closest skt, then out to shed in armour cable. Without upgrading the fuse board is there any way I can rcd protect the armour cable? Taking the armour cable back to the fuse board and fitting a seperate rcd enclosure is practically impossible. Thanks for any suggestions.

No actual depth specified in the regs.

Are you sure?

I was wrong to assume the cable would need to be rcd protected.

You could have been right if it was a TT system and not a TN-S.

Yip.just states the cable shall be buried at sufficient depth to avoid being damaged by any reasonably foreseeable disturbance of the ground.

Maybe look again!

I see nothing at all has changed around here. Someone asks as question and gets the p*ss taken out of them. No-one's taking any notice of:

Apart from agricultural/horticultural there is no specific distance given in the regs other than already mentioned that it needs to be buried at sufficient depth to avoid being damaged. Which in a garden is usually taken as from a spade! Based on this the recommended depth is between 500 - 600mm

So you are happy spoon feeding numpties. I see this thread as a minor success, the OP clearly has a regs book, knows where it is and has looked in it. I salute him for this.

No Murdoch I will not look again.

Well rather bizarrely his is almost absent in definition except in 701... can't remember the next number which refers to farm type installations.

This is yet another clear omission from the regs and does need to be defined so as my learned friend above has stated 500mm - 600mm - this is the generally "agreed" recommendation under soil/grass.

Stop getting "stroppy" and enjoy the banter ..... some is just a little bit more robust than others :smiley2:

Hi,

How are you planning on earthing the armouring? Are you going to be doing it at the house end, as ideally it hold as a minimum be earthed at the origin.

I would recommend taking it up into an adaptable box then tagging it to the earth, but then if it runs out to be a TNCS and you are extending the equipotentil zone, really you should be using a 10mm earth for the bonding of extraneous parts at the remote end if applicable.

Can you all please debate your points in a constructive and friendly manner please....!

In my line of work I don't do much of this sort of thing so out of laziness I asked on here. But it just seems to be full of smart arses. After checking the regs book I can see no requirements for rcd protection for cables buried underground. Reg 522.8.10 only states that a cable buried underground shall incorporate an earthed armour or metal sheath and should be buried at sufficient depth with suitable marking tape etc. sorry for any inconvenience. I was wrong to assume the cable would need to be rcd protected.

So you are happy to install a new socket circuit outside without any thoughts of RCD protection ???

I don't think that is what they are saying mate. The SWA cable going to the garden shed doesn't need RCD protection. Once in the shed a RCD will be fitted.

Two points I'd make here: 1. To the original poster... I wouldn't touch this. I'd recommend a mains board replacement and cable back to it or I wouldn't do the job.2. Threads like this remind me why I'm an observer on this forum and any other like it. Wouldn't dream of asking anyone for advice on here just to get lambasted from every direction. Even if the guy is, in your opinion, a numpty, answer him calmly, even advise he gets someone who knows what he's doing, but the way you lot rip into people is ridiculous and makes you look rather pitiful I reckon.
