|Thread: Electrical fuse selection|
hamish its more or less anywhere you might encounter water see
for more detail, regarding the freezer, it would have to be its own circuit, with the cable either not buried less than 50mm from the surface of the wall or with an earthed mechanical protection, such as the conduit mentioned. then a dedicated labelled socket just for that, or better a fused spur with the freezer permanently connected, things like smoke detectors as well dont have to be protected thats why on the better new boards theyre split 2+5+5 or so, 2 non rcd ways and 2 sets of 5 protected ways, you could still use a "16th edition" board if you were using surface mounted trunking or conduits and just have socket and special location circuits protected
under the 17th ed regs any sockets for use by ordinary persons in a house must have rcd protection, and any other circuit must have rcd protection if it is in a "special location" ie, kitchen, bathroom or outside,
then, in england and wales, under part p of the building regulations any new additional circuits or alterations to existing circuits in a special location must be tested and certified in accordance with the 17th ed regs, and reported to the local building authority, which costs around £180 for you to do or £1.50 for a registered electrician on a competant person scheme,
terence it sounds like you have an earth system called a TT system with a spike in the ground outside, and the earth fault path would be too high to certify unless an rcd was added, and to get around this sometimes the MEB put a 100mA rcd in to protect the supply, domestic circuits need a 30mA so its worth checking to see if its correct
