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

    Thanks, everyone for the great communication. I have spoken to Buffalo and Lincat regarding the same issue and suggested supplying appliances with just the heat flex so the installer can end off into a switched spur or commandos as the plugs seem to melt over time. The 13A fuse surprisingly holds however, the plug is melting and scorching the sockets which are making them brittle.

    In regards to moving the sockets to a location away from the heat, I had already relocated them with MK outlets which was difficult due to the limited space in the kitchen with nearby water outlets.

    The only option I hadn’t considered was rewiring the appliance as suggested by Broadgage. The last two options I offered the client was what I suggested here, or bring in a new 16mm feed into a DB and then supply what’s needed from there.
