Does anyone know the BS number for these RCDs?

Certification minor works blip - I need to issue this cert, but they are always checked by the clients M&E consultant, so need the correct number for sure.

Help appreciated as always.

Thank you OMS - is that an either/or reply?

It's either BS 1363 or it is 7288 depending on the manufacturer?

On my drop down menu - using easy cert - it has both options for the BS number of an RCD.

It's a both - the fused spur is in accordance with BS 1363-4 and the RCD protection is usurped from the standard for SRCD's ie BS 7288.

If you are making a claim on the RCD, then I'd go with BS 7288 (don't know if you can add a note to Eastcert to clarify ?)

Does your software list include IEC 62640 ?

HI OMS

Thank you. 7288 it is then.

The soft ware does not include 62640, nor is it a number that I am familiar with - I had to google it!

For those that are interested:

IEC 62640:2011 applies to residual current-operated devices (RCD) incorporated in, or specifically intended for use with two pole socket-outlets, with or without earthing contact for household and similar uses (SRCD: socket-outlet residual current devices). SRCDs, according to this standard, are intended to be used in single phase systems such as phase to neutral or phase to phase or phase to earthed middle conductor. SRCDs are only intended to provide additional protection downstream of the SRCD. SRCDs are intended for use in circuits where the fault protection (indirect contact protection) is already assured upstream of the SRCD.

I guess you need to decide what protection the spur is providing - I would assume "additional protection" only ?
