63 Amp Isolator

[Redvanman]

I'm running a 63A supply for a cooker and need to have a local isolator.
Apart from having a 63A main switch in a small enclosure, is there any thing else I could use which is discreet to put in the back of a cupboard.

Thanks

You don't 'need' to have a local isolator.

 

[Redvanman]

Your not suggesting that I run straight from the mcb to the outlet !!!

You don't 'need' to have a local isolator.

If its on a shared RCD I would put an isolator in!

 

[D Skelton]

Why not??

Isolator has no protection so what difference does it make?

 

[Redvanman]

No idea what reg no. it is but it does say something about being able to secure the circuit so that it cannot be turned on, which isn't a mcb. IMO

What are you going to use to isolate the cooker when carrying out maintainance?

Nonsense man! £1000 heading your way if you can find a reg that would prevent you from running directly from OCPD to cooker.

P.S. An MCB is a perfectly acceptable means of switching off.

Or to isolate the cooker when the shared RCD starts tripping.

 

[D Skelton]

What are you going to use to isolate the cooker when carrying out maintainance?

The same type of thing you'd use to isolate a lighting circuit when carrying out maintenace on that!

im gonna have to get regs book out now to see if I can find it.

lets hope so ah I will send my bank details :yes:

 

[D Skelton]

Don't worry about sending me your bank details, you won't need to! Now get digging!

 

[Mike66]

So that does that mean that you would not install an isolator switch to a cooker?

What about good working practice

 

[Octopus]

What about nuisance tripping???

 

[D Skelton]

All depends on the circumstances. Good working practice is a completely subjective term. Would you install 'local' isolation to every three plated light fitting?

 

[Mike66]

Getting warm I think. Looking at Memorandum of Guidance on The Electricity at Work Regulation

Regulation 12 page 26

 

[D Skelton]

What about nuisance tripping???

What about it? If the cooker is tripping then there is a fault on the circuit that needs rectification the same as anything else. Until then, it can be switched off integrally or at the MCB.

 

[Mike66]

The OP is not talking about a light fitting.

Go on commit yourself would you install a cooker without an isolator

 

[Redvanman]

How about 537.2.1.2 or 537.3.1.2
Fingers crossed

 

[D Skelton]

I have, and would again. Find me a reg that says I shouldt be doing so!

which doesn't necessarily prevent a N-E fault tripping the RCD.

 

[Redvanman]

Has everybody got the green book now moneys on the table

 

[D Skelton]

How about 537.2.1.2 or 537.3.1.2
Fingers crossed

537.2.1.2 can be met by the MCB. It could NOT be met by using a cooker control unit, so that one is irrelevant.

537.3.1.2 can be met by the use of a locking off device.

Try again.

I know my NICEIC inspector would be telling me I shouldnt be doing it. He made a comment when I installed a cooker isolator switch in a cupboard as per customers request.

Do you ever have inspections?
