Cooker Isolation?

[Noob2013]

Right, here comes a debate lol [emoji16]

I believe a cooker isolator should be accessible within 2 metres of the cooker for emergency isolation.

However, if the client does not want a cooker isolator in there "fancy new kitchen," can it be placed elsewhere, (eg. on the other side of the wall in the cupboard understairs providing it's lockable)

I always see debates regarding whether the isolator is for emergency isolation or maintenance.

I think there's some guidance in the OSG and it also reflects that of where a local point of isolation can be somewhere in BS7671, I think it's within 2m.

if they want it in a cupboard that's fine with me, but preferably the one next to the cooker.

strangely enough, I'm doing a kitchen tomorrow and he wants it in a cupboard.

as for lockable, I can't say as I have ever come across a lockable cooker switch?

There's probably something in what you say about emergency isolation or maintenance, I would imagine the cooker switch is not designed to be switched under load at a guess which would then suggest it's for maintenance not emergency isolation.

 

[uksparks]

Just thinking about it, if your oven was to go bang etc, you would switch it in an emergency. I wonder what the wording is with the literature with s new cooker switch...

It's a switch so it is designed to break and make load, if it wasn't then it would not be called a switch

Some switches are designed not to be operated under load, a light switch for example operates under load, but would you have a 50A induction hob say, on full whack pulling the whole lot then switch it off whilst under that load? Just seems wrong that's all.

I would rather place an isolator in the cupboard behind, than not have one at all!

I would not do the job without fitting one, its a bit like fitting a shower without one.

The kitchen im starting on this afternoon, the bloke wanted be to get rid of all sockets of the side and put them in cupboard so that he doesnt have to look at them, I did question how he was going to plug stuff in and he said drill holes through the surface which is stupid!

Just a query.- lol

Why would you install a switch that might be used in cases of emergency in a relatively inaccessible position which is unusable as its been locked ?

Being lockable is for maintenance purposes. It's not locked in normal circumstances.

No, the definition of a switch is a load break device.
An isolator/disconnector is an off load device.

The OSG in section H4 actually says that a cooker control until should be placed within 2 metres of the appliance.

Though very good practice and I would think common sense wise a good idea, the gudie is not actually quoting a regulation in this respect and therefore if you don't site it within 2 metres, your not contravening any regulations.

Unless you consider it as Emergency switching? Then you may need to look at Regulation 537.4.2.5 and BS EN 60204

Some good info there.

Would you consider an electric oven or hob as requiring emergency switching?

 

[malcolmsanford]

I personally wouldn't consider it. Though some do think that the cooker control unit is for emergencies.

 

[Simonslimline]

Cooker control unit switch, BS4177. Isolation (on load) = yes, Emergency switching = yes, functional switching = yes.

That is interesting Simon how does that comply with latching off if it is not under the control of a single person.

I have to be honest I'm not totally upto date with the BS 4177. So that would be interesting

I am just using the information in table 53.4, it does refer to 537.4.2.5

I suppose you are referring to 537.4.2.6

You don't even have to use a cooker isolator if you wish. The MCB can be classed as the isolation point

No longer a requirement for a Cooker Switch.

No longer a requirement for a Cooker Switch.

Is there anything in the regs stating that?
