thats going to p&& off some customers that what a extinction to a light .RCD FCU's no longer comply as additional protection to the 18th edition.
The requirement is to provide RCD protection for the circuit.
RCD FCU's no longer comply as additional protection to the 18th edition.
RCD FCU's no longer comply as additional protection to the 18th edition.
There’s 3 standards listed:
531.3.6 RCDs for additional protection
The use of RCDs with a rated residual operating current not exceeding 30 mA is recognized as additional protection in compliance with Regulation 415.1. These RCDs shall be provided to comply with the requirements of Regulation 411.3.3. RCDs for additional protection in AC installations shall comply with:
- BS EN 61008 series, or
- BS EN 61009 series, or
- BS EN 62423.
Where installed at the origin of a final circuit or a group of final circuits, an RCD with a rated residual current not exceeding 30 mA may provide fault protection and additional protection simultaneously.
NOTE: Consideration shall be given to the division of the installation (see Regulations 531.3.2 and 314.2).
So does that mean that in a metal containment system where no additional protection is required for the cables, the additional protection for sockets could not be provided by 13A RCD sockets ?
Technically yes. I have received verbal advice from NAPIT that I can continue to use RCD spurs and sockets, but they wouldn't commit that in writing as, and I quote "that's just my (meaning the advisers) interpretation of the regulations".
I have used a few RCD spurs (which are manufactured to BS 7288 I believe) for providing additional protection since the introduction of the 18th but these have been listed as departures on the relevant certs.
I can see that this is a sensible and compliant use of a departure. It can be proved it offers the same level of protection.
Would like to know the reasons for the change in these regs though.
