i am thinking of replacing wiring and sockets (ie) single to doubles ime not a sparky but confident ive inspected the wiring as it is and the power comes in to fuse box then 1 wire goes to socket then a wire from that socket to next and so on i no about ring main ive done a bit labouring for sparky but in ring main it comes back to fuse board this dont is this normal on caravans also what rating wire to use ive got a new lenth of hookup cable will this do or not the van is 20 years old

 

cheers aLL

You're quite right! Caravans are not wired on the house ring main system. The power comes in through the main switch and is then spl;it into a 13amp and a 5amp source. The 13amp feeds the power points and the fridge with a 10amp spur for the fanmaster. The 5amp feeds the mains lighting and the water heater. There's no reason why you shouldn't replace a single socket with a double, or indeed extend the line for additional sockets - always bearing in mind the capacity of the cable. Your old mains cable will be rated at 2. 5mm whereas the caravan wiring will be done in 1. 5mm

Not the best way to do it. .as you say the wiring should return to the fuse box on a ring. ..effectively doubling whatever the wire size used. Caravans generally use the radial system where one 3 core flex from the fuse box goes to each socket.

Wire size should be 2. 5mm for regs. .never understood this as it is backed by a maximum 16amp fuse/mcb which is OK on 1. 5mm flex? same size as your hookup

Remember, just because it's a Caravan it is still 240V, It only takes a few milliamps to KILL. For the sake of a few quid think of your family. The new regs allow for converting sockets into double but not a rewire. (I too am unsure if it applies to Caravans, however at some stage the van will be connected to the mains network).

 

Think on, the 'trician you laboured for spent at least 2 years at college during his apprenticeship.

Having read the posts about this subject, I have to agree with Wildcat, and say that unless you know what you are doing, and NOT relying on just watching someone else at work in a totally different environment, DONT do it yourself. you only have to make one mistake and you coul deasily kill yourself, or anyone who is unfortunate enough to come into contact with your "attempt" to do a job which, from what you have written, are quite obviously NOT qualifed to carry out.
