Connecting 32 amp socket to cooker circuit

[RF Lighting]

He has some strange beleif that SP RCBOs don't comply with BS7671 untli the DNOs have to comply with the ESCQR in 2013.

Just another incorrect post by holmslaw

Here we go again..... So where in BS7671 does it state that SP RCBO's are non compliant?

 

[RF Lighting]

Have you even got your self a copy of BS7671:2008 yet holmslaw?

You can get Interlocked Switch Sockets quite cheaply.
Basically a rotary switch & BS4343 socket combined, where the switch will not put power to an empty socket and could even be locked off (cable tie).

So you would change a domestic consumer unit and not give thought to protecting existing lighting circuits with a 30mA RCD?

Surely lighting (along with smoke alarms, freezers etc) should generally not be protected by an RCD.

BS7671:2008 says that ALL circuits with cables buried at a depth of less than 50mm in a wall or partition must be RCD protected (except if some other special precautions are met)

This is where RCBOs come in.

Hmm, that's interesting... You're right, that's what 522.6.7 says. My 'Guide to the wiring regs - 17th ed' from the ECA is wrong - that specifically says that if the wire is in the safe zones it's OK not to have an RCD.

(I'm glad our house was wired before 2008...)

A guide to the Wiring Regulations which contradicts what the regs say?

Surely not!

I hope it has a disclaimer in the front....

I think its just poor wording which causes confusion (very poor for a guide which is supposed to simplify BS7671). I take it that you're referring to section D7 Residual Current Devices, D7.1, 3rd bullet point (page 125)? Also notice the difference between installations under the effective control of skilled or instructed persons (generally commercial and industrial) and those used by ordinary persons (domestic).

why? if it was wired to the 17th you would have more RCDs making the installation more safe, and could (in most cases) do away with unsightly bonding cables and clamps in the bathroom, 17th looks good to me!
