EICR code- Cooker switch with a socket outlet lacking RCD protection.

Sparkingchip
1980's end of terrace house, MEM Memera consumer unit with a RCBO to provide 30 mA RCD protection to the socket ring circuit, but no other circuits have RCD protection and there is not any outdoor sockets at all.


There is a cooker switch incorporating a 13-amp socket outlet, which is the closest socket to the kitchen window and with 1.5 metres of it, this socket does not have 30 mA RCD protection, what EICR code should be applied and why?

    If the 50m extension lead is "reasonably foreseeable " then a C2 would be appropriate. How would you code the non-compliance?




    I shall stick with C3. We seem to be back to the debate about whether BS 7671 is retrospective. The installation has not at any stage suddenly become unsuitable for continued use. Nor was it any less "potentially dangerous" when it was compliant under an earlier version.


    I have been thinking about those 50 m extension leads.

    Table I1 of OSG tells me that the r1 + r2 of a 50 m x 1.5 mm2 lead is 1.21 Ω, which doesn't leave much slack for obtaining a Zs at the load end of 1.37 Ω (BS 7671 Table 41.3) presuming that a 32 A type B MCB is fitted. (Granted there will be a 13 A fuse in the plug, but that will that save your bacon?) Should these extension leads be fitted with RCD protection?
