rcd protection on sockets

[deanmac]

hi guys if a bank of 20 sockets wired in surface trunking on a radial circuit,these sockets would be used for computers gameboys and music equipment,my question is would they need to be rcd protected ? i know normally they would not,it's just that my mate said if protecting computers they should, i cannot find anything on this

 

[westward10]

so even though these sockets will be wired surface and only used for computers they will need rcd protection ?

Is this a domestic installation.

Also you need to choose the right type of RCD especially for computers in that kind of quantity.

411.3.3 Additional protection requirements for socket-outlets and for the supply of mobile equipment for use outdoors
In AC systems, additional protection by means of an RCD with a rated residual operating current not exceeding 30mA shall be provided for:
(i)socket-outlets with a rated current not exceeding 32A, and
(ii)mobile equipment with a current rating not exceeding 32A for use outdoors.
An exception to (i) is permitted where, other than for an installation in a dwelling, a documented risk assessment determines that RCD protection is not necessary.

If the sockets are intended for specific items, then no, RCD protection is not required.

yes

It is still in the 18th Ed.

No it seems to have been changed.

 

[westward10]

yes

They need additional rcd protection then, why are you trying to avoid it.

i am not trying to avoid i thought because they will be for stereos and computers and not outdoor equipment then they would not need it, also to prevent tripping and knocking half the house out,although a rcbo would sort this

 

[westward10]

No it seems to have been changed.

Slightly reworded but in essence it is the same.

Slightly recorded but in essence it is the same.

So the exception for labelled sockets for specific equipment has been removed.

personally, I'd fit a dedicated RCBO. then it can be switched off/locked off when his mate wants the kids to go to bed.

But not in domestic.

You do need rcd's protection, you cannot get out of it.

 

[Deleted member 26818]

You can get out of it at present, just by labelling up the socket with the item it is intended for.
When the 18th kicks in, you will have to either provide RCD protection, or cut off the plug and use an SFCU.

Personally, I can see some installations in the future with departures.
