Hi There,
First post so be gentle.
I've been asked to install a trip switch on a 2 bed holiday chalet, where each of the chalets is supplied from the holiday park's mains on a 30Amp 1361 main fuse cutout. However the owner of the chalet has already blown this fuse twice (at £50 a pop to callout the on site sparky). I've not seen the chalet, just some photos of the consumer unit, but he says there is a plug in cooker (13Amp), small immersion/water heater, the usual kettle/ toaster/ microwave/ hairdryer (not sure what the hob is) arrangements for a holiday cottage. The owner is justifiably concerned that whilst he is aware of keeping the total demand down, his visitors might not, and he doesn't want calls asking him what to do all the time.
I thought i'd install an additional 32Amp, 30mA RCD before the CU (unless i can get it in the CU), and after the suppliers 30Amp fuse, (there is no RCD currently). My thinking is that the actual tripping capacity of this would be lower than the 30Amp supply fuse. But i'm struggling to find confirmation on this.
The alternative is to put a 25amp 30mA RCD in, but this is almost definitely going to trip at breakfast time each day.
Unfortunately the chalet is 150miles away and i'm off there this weekend to carry out the work, (including testing and certification) then spending the rest of the week there kicking back with the family. I think its a 60mile round trip to the local wholesalers to pickup bits so would like to take as much as i can with me to be on the safe side.
Any advice would be appreciated.
Many thanks
