Commercial Kitchen Sockets

Andy Barton

Good Evening Everyone,

The following issue I have been following for a couple of years now, and it's in regards to 13A sockets burning out in commercial kitchens. Everyone seems to recognise MK sockets and plugs are of a better standard, however, they are still burning out on griddles and fryers. 

Dependent on the client, they are open to changing them to a commando and not worrying about voiding the warranty. The kitchen in question has two 32A feeds and each feed supplies two 1G sockets as each appliance has two plugs. 

After much deliberation I think the most economic solution is to put two 32A surface commandos on each supply then make up a 32A commando connector going into a mini DB with 16A RCBOs and then two 16A flying commandos wired in H07RN cable to supply each connection on the appliances. 

In an ideal world, I would bring in four new 16A supplies from the DB each having its own RCBO. However, the run is long and the client wanted a cheaper option. What are everyone's thoughts on this is I'm open to trying to find a solution as almost every kitchen seems to have the same issue when grease and water are involved. 

Thanks in advance,

Andy

    An alternative approach that I have used is to modify the appliance.

    Fit inside the appliance a couple of HRC fuse holders with 16 amp fuses. Fit a single 6mm flexible cord HOFR or other suitable type and supply this from a single 32 amp ceeform plug and socket.

    This works excellently IME. 32 Amp plugs and sockets stand up well to heavy loads, and in this case are probably only loaded to 26 amps and not to 32 amps.

    Even simpler is to omit the fuses and simply connect both the original inputs internally to a single 6mm flex and then to a 32 amp plug. This is in my view poor practice as the appliance is now protected  by an OCPD of more than twice the intended capacity.

    Suggest that any replacement appliances be the type fitted with one 32 amp plug and not the two times 13 amp type.
