Just to satisfy my curiosity, are you using main RCD, RCBOs or none of it?

my involvement in commercial and industrial properties is very limited, so I just wondered what you guys do...

My assessor said with all that metal about in a commercial kitchen if a faulty kettle or something was put on the surface and the is a high impedance there is a good chance a lot could become alive which is not a good thing obviously.Batty

dont see how this situation is any different to plugging in a faulty appliance on any other metallic surface. if there is a fault, the appliance should be earthed via flex, not via table

I have only RCD protected the general use socket circuits by using a RCBO, all the cabling is singles inside PVC trunking and conduit... have a look at my gallery for some photos...

I have added a couple more photos for the Crabtree VS Proteus debate..

the proteus doesnt look too bad, apart from the earth & neutral blocks only having one shared between both sides
