Hi all, going doing a few small jobs in a pub later this week. One of which is shocking, literally. In the cellar bar they have an electric dishwasher that is on hire and has been pat tested. It is opposite a steel bottle fridge, the new landlord informs me that if you have 1 hand on either appliance and then touch the other you get a shock. both these appliances may be fed off different dis boards. the land lord has had dish washer inspected and tested by the hire company and it passed. the bottle fridge and dishwasher does not give a shock on there own. he has unplugged the dishwasher but is still using the bottle fridge. obviously there is a pd between them and some earthing issue. can you have a potential diff between the 2 earths if fed off diff dis boards or just earth fault on bottle fridge. Any ideas before i have a look. Cheers
