appliances in kitchen having seperate switching eg by fused spur

[oxocube]

Heres a simple test for all those that believe isolation points don't have to be visible or obvious, and hidden behind other things means accessible and acceptable.

Sit on the cooker and turn on the hob, and then get someone else who is unfamiliar with the installation to find the isolation point and turn off.

Can we watch you do it?

The position of an isolator, is always going to be determined by why isolation is required.
If isolation is required purly for maintenance, then it can be just about anywhere if it is lockable.
If it's for functional switching, then it would need to be fairly close to the appliance, and fairly easily identifiable.
If it's for emergency switching, it should then be in a readily available and safe position, and clearly identifiable (i.e. big red labeled switch).

Would say intergrated appliances built into units should have fcu above and most other appliances not, although I tend to fit one for any under counter appliances also

i can just see a row of cast iron fireman's switches in a nice new kitchen

Thanks to the fact that ours is induction, this wouldn't worry me too much

Would be OK now the height of them has been lowered for short ar$ed firewomen.

I have on occasion installed flex outlet plates then wired the appliance directly into these which are then protected by FCU above worktop. That way you can safely isolate without having to pull the appliance out and you only have to worry about the fuse in the FCU which is accessible.

I can just imagine your garden, a 11/0.4 kv tranny, feeding a small .5MVA board. bet youve got a herater that can take paint off the opposite wall.
All cables hidden away, in nice black enamel/steel conduit. All appliances in kitchen indicidually isolated by MEM switch disconnectors.

With the addition of the stop starts for the washing machine and dryer and the external compressor unit for the fridge, and the 5 Hp submersable pump in the Bath,the jobs a good un

When using grid switches for say a washing machine and tumble dryer in a utility. If you take both legs of the ring into the box, one leg into one DP switch the other leg to the other switch and link between the two, you would have to use 4mm2 T&E to the unswitched socket outlet as 2.5mm2 wouldn't be protected by 32a MCB? Any other way to do it?

Does the cable spuring off the RFC require any protection?

 

[ash_s3]

Didn't think of it like that! Exactly the same thing really.
Doh!

I thought about that as well then say you have oven,ccoffee maker,microwave.dishwasher,washing machine ect you could have 8 9 way grid switch on a RFC with 9 spurs off would that be 1 practical? 2 alllowable??

Each DP is looped in the ring so its not spur off of spur
