Amendment 3 is getting closer- find out about Risk Assessment changes

[AmtechGroup]

The BS 7671:2008 Amendment 3 changes are coming ever closer. We are producing a range of white papers highlighting the main changes affecting electrical contractors and designers. Our latest concentrates on Risk Assessments for the Omission of RCDs for Socket outlets.

Amendment 3 proposes changes to the regulations governing the additional protection by means of an RCD for socket outlets whose ratings do not exceed 20A. Under the proposed changes, if the designer decides that RCD protection is not required, he then must provide and document his reasons for their omission. This should be provided in the form of a Risk Assessment and appended to the appropriate Electrical Installation Certificate.

You can download our free white paper for full information and sample Risk Assessment forms.

just typical scouse/geordie banter. them geordies just can't come to terms with not being able to climb hadrians wall, so they nicked all thew stones instead.

so do i.:

Geordie git muss Zementmantelfiel in mersey

Waddya mean "Geordie git must cement mantle fell in mersey" ???? :whatchutalkingabout

 

[Pete999]

Getting serious for a minute, if I'm reading that document correctly, and knowing me there may be something I'm missing, it sounds to me as if they are saying a 32 Amp RFC should be RCD protected, yet if you put a 20Amp radial with socket outlets on it and you don't want to fit an RCD you need a RA am I right? or have I drunk to much of the red stuff and gone brain dead, serious answer please Tel

In any situation where an RCD is required for a socket circuit if you have a documented risk assessment showing it not required then the RCD may be omitted is the proposal.
It just means there will be generic RA forms produced that state "this circuit has been competently assessed and due to the nature of the use of the socket outlets an RCD is not required" and attached to the EIC.

PART 4
PROTECTION FOR SAFETY
CHAPTER 41
PROTECTION AGAINST ELECTRIC SHOCK
411 PROTECTIVE MEASURE: AUTOMATIC DISCONNECTION OF SUPPLY
411.3 Requirements for fault protection
411.3.3 Additional protection
In a.c. systems. additional protection by means of an RCD in accordance with Regulation 415.1 shall be provided for:
(i) socket-outlets with a rated current not exceeding 20A and
(ii) mobile equipment with a current rating not exceeding 32 A for use outdoors.
An exception to (i) is permitted
(a) for a specific labelled or otherwise suitably identified socket-outlet provided for connection of a particular item of equipment, or
(b) where a documented risk assessment determines that the RCD protection is not necessary.
NOTE 1: See also Regulations 314.1(iv) and 531.2.4 concerning the avoidance of unwanted tripping.
NOTE 2: The requirements of Regulation 411.3.3.; do not apply to FELV systems according to Regulation 411.7 or reduced low voltage systems according to Regulation 411.8.

problem arises if the cable/s to said sockets are buried <50mm deep. the sockets mught not require RCD but the cable will ( unless other forms of protection are used).

Yes Tel I was trying to put words to that thought, this new amendment seems to contradict it's self, on one hand it's sockets rated at 20amps or less they don't need RCD coverage provided there is a risk assessment covering the reason, but you're right if the cable is less that 50mm buried and not protected it needs RCD coverage, it being the cable, I see trouble ahead.
