I would appreciate any advice on a job I have coming up which is a small pizza production kitchen.All the equipment is fixed floor standing with their own built in DOL switches.The main item is a pizza tractor/conveyor belt oven 32A plug and three processing machines with small motors 16A plugs.The walls are white gloss painted brick and I think I will use white PVC conduit to industrial sockets for each machines,each with its own rotary isolator and type C MCBS.All wiring is on the surface and the user is a skilled chef so I would think I don't need any RCDs?
