Kitchen Grid Switch for Oven? (Customer Request).

[8yf13l0]

Hi all.

I am back again with my dodgy questions lol.

Customer wants a multi way gridswitch to control various bits in the kitchen.
Few light switches, cooker extract fan, fridge, Washing machine, Dishwasher etc.
But they want a cooker controlled here to??

It's a 32A 6mm supply to the A.I.O Electric Cooker.

I have explained to the cmr the best you can get in these grid DP switches is 20A which is not big enough for the 32A cooker supply, but the cmr wants this to be achieved at all costs.

Has anyone faced this dilema before?
Would a compliant solution be to use the 20A grid switch to operate a coil for a 32A+ rated contactor to connect/disconnect cooker supply safely?

Any suggestions???

Many thanks

Jamie.

never seen a 32A grid module, its either a separate switch or a contactor/relay if they willing to pay...
you can get a din rail mounted one and install it in the consumer unit.

If it's gotta go in a grid switch the sounds like the best plan to me, although you will have to mount the contactor in a accessible location

...Maybe set up a small panel,with a few contactors in there,to lessen load on that grid...go all "mission control",and dazzle em' :smartass:

Ok great.

Is there such thing as a 32A (or over) 2-pole contactor with din rail mounting capability as I cant seem to find one??

Or am I likely to end up using a 4-pole for this???

Regards

Jamie

Why 32 amp? have you allowed for diversity?

I prefer not to allow diversity to cookers because on christmas day and special occations diversity seems to go out the window lol.

I've only seen max 20A 2 pole contactors, not saying you can't get them but possibly hard to come by.

Might aswel use a 3/4 pole...

I kind of quite like the idea of having it going via a contactor, I guess whichever way you do it, you will end up with an enclosure containing circuits from more than one mcb, but that's no different to a stair light switch really.

A distribution board is an enclosure containing multiple circuits. Hardly a big deal.

Re: Kitchen grid switches - cooker??

Totally agree, I just try in domestic settings to minimise enclosures containing multiple circuits due to diyers not isolating both circuits, not always possible I know.

oh dear, well if you say so pmsl.

TBH the price difference between a lower rated contactor is going to be negligible

Click minigrid do a 32A double width switch that can be installed in their plates, however that may still not be enough rating.
