summer house socket

[fencer]

Hello peeps
Just a quick one (i hope), I want to take a spur from a ringmain out to our summer house, can I add one of these (Powerbreaker H92IP IP67 Waterproof RCD Fused Spur Unit).

to the ringmain then take the spur from here out to the summer house. Having read posts on here I was thinking of running 4mm armoured cable from the rcd fuse spur unit across the 9 meters to the summer house, where I'm planning to run a single socket.

How does it sound.

Thanks for any help or tips

what you propose sounds fine. Put a double socket in though. single sockets are rarely enough.

is the ring main RCD protected? if so, you dont need an additional RCD.

Thanks crafty, no the ringmain doesnt have a rcd only mcb. hence having read other posts I did a search and came across the spur rcd
Once again thanks for your help.

When you're running the cable across the garden, keep a look out for the Part P police
