Swapping out a cooker switch

[davesparks]

Really I am sure that you can follow that the specific wording of the phrase "additional protection device to protect people from drilling holes into cables" would be interpreted as "protect people from the effects of drilling holes into cables" or "protect people who are drilling holes into cables".
A slight miswording of a phrase is not something to get steamed up over.

Yes it is, an electrician should be a skilled tradesman in a technical trade. If they can't get something as basic as this right then they should not be allowed to practice the trade as they could place people's lives in danger

An RCD is an additional protection device to protect stupid people (from) when drilling holes into cables less than 50mm from a finished surface...........

I've amended Paul.M's post, which is what he meant, I think. Anyhow, hardly worth arguing over, a word that is.

If a drill or nail hits an energized cable, the RCD will operate. What is wrong with the above statement??? It protects the operative of the said drill or nail and not the regular timing of their heartbeat. (are you thinking/talking about mechanical protection? See below).

No it isn't, it does nothing to protect people from drilling holes in to cables, it reduces the likelihood of them receiving a fatal shock when they drill into a cable and make contact with a live wire.

All the "people" have to do is buy a Part P Regs book @ £16 and understand about safe zones. Simples!

PS, we now call them LINE

Then by definition it 'protect(s) stupid people from drilling holes into cables'. Think your splitting hairs.

Yep and this can get surgical if it continues?

Pedantic.......

Agree, why the hell am I spending time writing this when a first year student understands the context of this thread or what was said in the first place?

No it doesn't! It does not protect them from drilling the hole, it limits the severity of the electric shock they receive once they have drilled the hole.
How on earth would an RCD protect someone from drilling in to the cable?

They need to buy a Part P book before putting up that Ikea picture frame or mirror.

No it's not 'whatever'! There is a big difference between protecting someone from drilling in to a cable and limiting the severity of the shock they receive if they do drill in to it.

The "whatever" post was directed at you. Nice to see your looking at this thread now, got your attention???

Any time you are stuck on a Reg question on site, just send me a PM I'll give you the answer.

All the best

Btw as per the HSC, 88-90% (GN7 btw)... We cant protect everyone. Some people just cant take a 30mA shock.

Ps most people have a class II drill...... Whatever......

Good grief

It's Dingledong where have you been hiding.

Yep I'm dropping it. We have both said our piece. It has become childish now. PM me if you want to chat.

Have been asked to disconnect a 40A fixed line to a cooker. The new cooker is apparently a '13A, 3 pin' one, though I'll believe that when I see it. The cable isn't being removed, so it needs terminating properly. I was thinking it could go into a new plug socket, but then the RCD for the circuit would be too high. Have been looking at
1) Swapping the isolator switch for an isolator switch with a socket, and just leaving the cooker switch on this unconnected and non-functional
2) Wiring in a double socket with a built in RCD

What do people think?

Removed to keep forum harmony.

Not far enough away unfortunately.

Not enough info, but assuming it has a 100mA RCD and that is why the "the RCD for the circuit would be too high", rather than it being too far up the wall, why not swap the cooker outlet plate for a 13A fcu?

Chop the plug off the oven, and wire into the FCU. No socket, no RCD required. Obviously note the lack of RCD protection for the concealed cable(s), if any. But you didn't install it/them so you can only advise the customer that the situation needs improving.

As an aside, my understanding is that RCDs limit the duration of a shock (otherwise we wouldn't be testing trip times, would we?). Whether that's the same as severity is open to debate. :smartass:
