P.M.E. and Potato Peelers.

Zoomup
About 2 years ago I was asked to undertake electrical work at a local chip shop/fast food outlet. I was concerned about large metal drummed wet potato peeling machines located on a wet floor in an old outbuilding and the P.M.E. earthing system. I could not devise a safe system in my mind where the large potato peeling machines positioned on a wet stone floor could be made safe with the P.M.E. earthing.


Anyway, unfortunately recently the place burned down and is now boarded up. The cause may not be electrical, but due to oil catching fire.


I have not done any work in the building at all.


Because the machines could not be effectively TT earthed I did not proceed with any work.

    Our local chip shop is TT with a single upfront 30 mA RCD, which from a safety point of view is great, a single fault shuts the entire place down, as has happened just at opening time with everything ready to go into the fryer.


    There is now a spare RCD and breakers in the cupboard with the consumer unit, because I had to get spares posted over from Northern Ireland and it takes time.


    Personally I would rip the consumer unit out and replace it with an all double pole 30 mA RCBO consumer unit and a 300 mA upfront RCD in the tails, but I’m not the one who pays the bills so it will stay as it is unless there’s a complete loss of power for an entire shift.
