Commercial Kitchen Sockets

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

  • In a situation like this, I always look at what the big boys are doing. Go and look at a McDonalds kitchen, and everything is on Commando sockets, from 16a single phase, up to 63a 3ph. 

    I remember when appliances used to say something like 'if the plug isn't suitable for your sockets, replace it and ensure its protected by a 16(15)a fuse 

    I would specify RCBOs now, especially with them being metal appliances, in wet places, with concrete floors and most chefs tend to be wet too.

  • Agreed Johno12345. I have been involved in the hospitality industry most of my working life and anything rated 3Kw or above were connected to Commando sockets on separate radial circuits. If there was a square pin plug on the appliance, it got cut off. 
    As an aside, when it came to the robustness of electrical safety in such places, the client had no say. It was my way or no way!
