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.
