main switch question

[Deleted member 26818]

There is no requirement for RCD protection of socket circuits, unless the installation is considered a special location.
Just wondering whether the meter is single or 3 phase?

 

[shanky887614]

yes there is if its under 20amp supply. ill dig reg out of byb later

Good luck with that.

Thanks for that, as you can see from what you have quoted, there is no requirement for the circuit to be provided with RCD protection.

Socket-outlets are required to be provided with RCD protection, not the circuits supplying them, except in some instances where the installation is considered to be a special location, such as Horticultural or Agricultural.
In fact providing RCD protection for such circuits could be a non-compliance in some circumstances.

if the cable is not more than 50mm in wall or has mechanical protection then it needs an rcd

Exceptions still exist with a risk assessment

unless its a dwelling then no you cant skip it

Who mentioned a dwelling ?

Still no requirement for socket circuits to be provided with RCD protection.
Yes there are circumstances where it may be advisable, or the simplest solution to provide RCD protection for such a circuit.
However it still remains that there is no requirement in BS7671 for such circuits to be provided with RCD protection, except in some circumstances where the installation is considered to be a special location.
Doesn't matter whether there is a dwelling involved or not.

do you realy need to ask that?

yes. Why not?

411.3.3

Addition Protection RCD

Socket outlets not exceeding 20 A

Ammendment 3 does not come in to effect until 1st July 2015.

Yes socket-outlets, not the circuits supplying them.

 

[Leesparkykent]

The difference is the regulations say socket outlet and not circuit. For example you could have the circuit installed surface so doesn't require RCD protection but you would install a RCD socket outlet to comply.

No, it came into effect on the 1st Jan 2015 but the 'old' regs don't cease until the 30th June 2015 so the 3rd amendment is actually Currently in effect.

It was published on 1st January, with an effective date of 1st July. So BS 7671:2008 (2013) is still current.

Wrong! this is of the IET website;


Amendment No. 3 to BS 7671 Wiring Regulations will be published on 5 January 2015, and will come into effect on 1 July 2015. The new reference for the book will be ‘BS 7671:2008+A3:2015’.
All new installations must comply with BS 7671:2008+A3:2015 from 1 July 2015.
In this update, a number of potentially life-saving changes have been proposed, which include, but are not limited to, changes to:
consumer unit enclosures (to come into effect January 2016);
wiring in escape routes;
changes to earth fault loop impedances for all protective devices;
the risk assessment approach for the omission of RCDs in non-domestic situations;
updated EIC and EICR forms; and
changes to definitions throughout the Wiring Regulations.

 

[Guest666]

Sorry.

Then there's yet another error in the book as it clearly states July!

 

[Anthony S]

Sorry.

What you done now lol

Does it count if my book says 01/01/15 in crayon?

 

[Deleted member 26818]

Pleas note, the only place in BS7671 where requirements for circuits to be provided with RCD protection is to be found, is in the section for special locations.
Such circuits are those of a location containing a bath or shower, circuits supplying socket-outlets in Agricultural/Horticultural Installations, etc.

Yes it may well be that the easiest or most cost effective solution will be to provide RCD protection for socket-outlet circuits, rather than individual socket-outlets, but there is no requirement to do so.
It should also be considered that some circumstances, providing RCD protection for socket-outlet circuits can cause nuisance tripping, and could actually be a non-compliance.

Bought it so might as well use it.

 

[HandySparks]

Bought it so might as well use it.

Bought life assurance. Don't fancy using it for a while.

 

[paulthemagpie]

yes correct and in this case the socket circuit will have rcbos and the main switch not rcd.
