Hello. I am thinking of fitting an outside weatherproof socket unit. I will run the cable back through the wall via a surface mounted box to a kitchen socket where it will be plugged in with a 13 amp fuse. I will use 2.5mm square cable and trunking. The kitchen socket is already covered by an rcd on the consumer unit. Is it necessary to have an outside socket unit protected with an rcd when the circuit is already covered by the consumer unit rcd?
 
far better to spur off the rear terminals of the internal socket. but if you want it to be plugged in use 1.5mm flex with a 13A fuse in the plug. do not try and fit T/E into a plug.
 
No. You don’t need another rcd if the circuit you’re coming off has it.

Also, 2.5 t&e will not fit into a plug top.

by using the 13A fuse in the plug, you could use 1.5mm flex instead.
Hello. you have confirmed what i was thinking. many thanks for your help.
 
If the cable will be exposed to sunlight then use UV resistant cable. This is suitable and sold be the meter in many places:

Ideally you would use ferrules on the fine-stranded wire at the back of the socket (sometimes for plug tops as well), though many don't and it might be a bit of an expense for a one-off DIY job. But if you do odd things like this a lot then something like this would do:

Finally please test the socket before use! At the very least one of the basic socket test tools, but if you can afford it then the better ones like this tell you if the earth is at least half-decent:

If your house has not had a recent electrical inspection (EICR) then it is well worth spending an hour or two with such a tester going round every socket and checking it passes, looks OK (no cracks or evidence of thermal stress) and the switch action is good and positive.
 
If you don't have the ferrules, then for the socket end strip about 2cm of insulation off the fine stranded wire, twist the fine strands together a bit, and fold them back half-way so you have about 1cm doubled-up for the terminal to get a good grip of.
