I have just moved into a new build house and I am looking to install power into the garage (detached but within boundary). Speaking to the site foreman he informed me that they were going to provide this as standard but it was abandoned prior to completion. Luckily for me they have laid the conduit with armoured 3 core cable in it, all had to do was find the ends 
. My puzzle is what are the regs and was the sparks doing it following them.
The Garage end is no probs, I am going to get a garage CU from Screwfix ready with RCD and 2 breakers, but I am confused by the house end. The sparks for the site has brought the cable into the back of a double socket box in the house as if all he was going to do was spur the cable off of the socket with no protection in the house.
Firstly I don't think the cable is deep enough and has no marker tape above it. Are the regs different if it is not on public land
Next as a new installation should he not have brought it back to the main CU.
As it is not from the CU should it not have some form of independant protection such as a fuse or RCD or does it not need one with an RCD in the garage.
My thought is to cut in a single box below the socket (carefully) as this is the direction the cable comes in and remove it from the double box above. I can then fit protection into the single box and extend the ring main into the lower box. The question then is what to use? The only RCD from Screwfix is limited to 13A, is this the right device?
