Wiring Shed to External IP67 Socket Adapter Ask questions and find answers to many subjects relating to electrics and electrical work

[B-i-l-l-y]

I have recently had my garden fully wired (radial system ... unsure that means) in each corner by a profession electrician. I have been informed that I can run electric heaters, kettle, etc. with no issue and it runs from the consumer unit in my garage which I think is connected to a 65 amp RCD fuse and he said if I wanted to run power to my new shed then I can merely spur off of one of the double sockets to a separate fused switch.
Ok so what I want to do is be able to move my shed in and out to maintain it every year so was thinking of using a one of those IP67 adapters like you see when connecting caravans to cars, so having a fixed socket on the fence and have a trailing flex from the shed. The trailing flex I was going to attach to the shed and then on to a new smaller consumer unit in the shed (x1 for lighting and x1 for plugs) ... does this sound ok?

I'm a competent diy-er just wanted to know the best (not necessarily the cheapest) way to do this and what parts to look out for, cheers for any advice?

IP67 sockets are expensive, in the main IP54 is good enough, there are two ways to wire outside.
1) Total sealed.
2) Allow any water which enters to drain out again.
In the main the second works better, as although we think totally sealed often it is not, and as the sun warms it and it cools again it sucks in water.

There are posts made for caravans with RCD and MCB built in, you are looking at £50 plus, is it worth it?
