    If the said socket outlet circuit is subject to high earth leakage current then the circuit needs to be wired differently than a normal Ring FC or Radial FC as per Regulation 543.7.1.201 information can be found on page 81 OSG and Figures 7.5.3 (1) and 7.5.3 (11) Page 82 OSG

    to omit RCD protection for these sockets, you would have to do a written risk assessment justifying a reason why. what's to stop someone plugging in a faulty appliance?

    Hi - As Pete has said.
    For RCD see Reg 411.3.3 :)

    Isn't the risk assessment, not for residential (apologies for my grammar) and no longer current in the 18th?

    Unless the sockets are intended for specific items of equipment, they will need RCD protection.
    Haven’t gotten round to checking whether the 18th has changed this.

    I thought that the 18th made rcd's mandatory on sockets and lighting circuits ...

    Risk assessments do not apply to domestic installations with regards to omitting RCD protection.

    Are these items likely to be unplugged and perhaps taken to other locations?

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