re: wiring in a kitchen extractor hood

[bonn1ett]

Hi all,

just looked at a job to install a kitchen extractor hood, have a few questions if anyone can help!

• The easiest and quickest way to supply the extractor would be from the cooker switch into a FCU with 3amp fuse - is this acceptable?

• Above the cooker, roughly in the middle of the wall is a large metal cover plate (quite old), after removing the cover plate found a terminal block connecting the 6mm supply cable from the CU to 6mm cable going to the cooker switch. The customer asked if i could fill the hole as it looks quite ugly. Customer does not want me pull cable out and redo as the wall is all tiled. If i crimped the connections or heat shrinked then filled in the hole - would that be ok? Also once the cables are then hidden in the wall and not obvious to anyone that they are there - is there not a problem with cable zones? The circuit is rcd protected.

thanks

Yes Mark what you suggest is fine. Just make a note on the cert regarding the cable route above the cooker for the next spark.

Hi Paul,
thanks for response, i will make a note on cert. Just like to make sure everything complies to the regs as it should do!

cheers

If you bury cables in the wall and the zone is then no longer obvious then it will not comply

Isn't that where the extractor hood will be?

I agree with what you are saying but if the customer does not want their kitchen wall ripped apart to re-route the cables then what are my options? Could i not state this on the certificate? Either that or i inform the customer that it will have to remain as it is?

actually now i think about it the face plate is directly vertically in line with the cooker connection unit behind the cooker and then goes from the plate in trunking vertically so wouldn't that comply with regs?

The hood would be going just above the plate so would still be seen and is larger than a double socket size

I think what he's getting at is if the cooker hood is above it it creates a safe zone. Or I may be wrong. Why would it be connected there or was the original cooker unit there?

I cannot work out why there is a cable connection there? Seems to me a very strange way of routing the supply cable to the switch but the property (ground floor retirement flat) is fairly old. Just need to weigh up the best options really.

Might be a old shower cable that they reroute and wasn't long enough. Just make sure it's in a safe zone and a maintenance free connection if its to be covered. If your connecting a FCU above it ie in centre of the hood it's will be in a safe zone.

ok, thanks for your advice, most appreciated!
