[QUOTE="gozzer66, post: 393014, member: 7223"] Hello. Ive recently been working in a hotel in N Wales, was asked to look into why a 12kw water heater was tripping the mcb, it was 32 amp run in 6mm. Told him to change to 10mm and 50amp etc. When i looked more closely at the supply intake, discovered that the whole 5 bed hotel is single phase and protected by a 60amp main fuse. There are electric showers in all the rooms, electric cooker and all the usual ring mains and lights etc. I advised changing the water heater to 7.5 kw and looking into getting 3 phase brought to the hotel. They reckon that they have been there 10 years and never had a problem. The main fuse seal has been renewed ?when, the old seal is broken and left on top of meter. I was going to look inside main fuse carrier to see what is in there. Does anyone think this is an odd situation or have any thoughts. [/QUOTE]
