adding DP 3 Amp Spur

[harvybcn]

Hi,

I am installing a cooker hood and the manufacturer requires to connect it fixed to a 3A DP Spur. My options for this are:

1. Connect it to Junction Box that has the In from the mains and Out to the cooker.

2. After this there are 2 JB around the boiler. One JB supplies to a ring of 5A fused spur, and two single sockets. Then a second JB getting the return from this ring towards the light.

Where can I connect my Spur?
What type of wire, 1.5 or 2.5mm?

Thanks

3. Call a registered electrician to comply with Part P of the Building Regulations.

1st option) You don't want to take a feed from cooker circuit, that is best left solely for cooking appliances, as this circuit could well have been loaded up to maximum.
2nd option) Hard to say by your explanation, what the true configuration of this circuit is and a little further investigation would be required with regards to load, spurs and discrimination of circuit
3rd option) Call a registered electrician to comply with Part P of the Building Regulations and several other building regulations as well as BS7671 (wiring regulations)

It's a kitchen and will require notification to building controls, which when DIYing, the fees can be quite tasty. You will need to have documentation of test results and either an electrical inspection certificate or a minor electrical works certificate issued. This will require professional and calibrated test equipment to be used.
No disrespect, but evidence shown in your post, would suggest that you unfortunately do not currently possesses the knowledge to complete this task safely and competently.
So options 3 sounds like the best one.

I do. Then it goes off in the emergency when switch is used in panic.

as this circuit could well have been loaded up to maximum.

Or not.


Agree with the rest.

Opinions will vary!

Of course it should be on the same circuit - it is part of the "cooking appliance".

BGI IMO to have 1 switch to hit and stop the hood drawing flames into it when the chip pan catches fire.

As for the loading - if he'd asked if he could swap his cooker for one which was 500W more powerful you'd say "No", would you?

EH????????????

Personally I don't add things to the cooker circuit, but can see the merit in the earlier comments.

You can find a suitable point on the socket circuit.

You can even come from the lighting circuit above if it's easier.

Is it?
It's part of the kitchen extraction, that does not necessarily mean that its sole purpose is to babysit the hob.

I wouldn't say yes!

Thanks all for your replies. Yes, I have no experience with electricity and I thought it could be a simple DIY job.

Can I function the hood as a plugged appliance to any of the existing sockets?

Any suggestions where to a find a certified electrician?

Thanks

Even the simplest of things are seldom simply, if no experience

That would depend on the hazard the flex may introduce to the location and whether external influences could also damage the flex.

Any suggestions where to a find a certified electrician?
