Hi All,
I am planning on running an extension lead from my shed to my summerhouse. Going to drill a hole in both walls, remove the plug from the extension cable and feed it from the summerhouse to the shed, put the plug back on and plug it in. The distance between both walls is only 200mm. What should I use to protect the cable, and stop water entering both buildings ? Was looking at Kopex, but would prefer something that would stay in place. ie Threaded ends with plastic bolts so it won't move. I know it's such a small distance but dont want the neighbours cat knawing at it !
(17mm TG to 13mm OSB)
Any ideas, thank you in advance

Why not have it wired properly?
An extension lead is not supposed to be a permanent fixture.

You need to check the regulations as to what is and what isn't permissible. What you propose is bad practice and possibly illegal or contrary to regulations.

What is the ground between the buildings? Soil, grass or paving slabs etc.

Can you bury a permanent cable with entry points in the floor of both buildings rather than in the side walls?

Armoured cable would be best terminated properly at both ends.

Thanks
The gap between the two buildings is impossible to get to. Its around 20-25cm width but there's an overlap on the summerhouse and you can just squeeze your hand through. As I have a socket in my shed already, I propose to use it as an extension lead, thus only plugging it in when needed. I am hoping this would bypass the "permanent fixture". Okay you would have to unwire the plug to remove the socket. Its on an active RCD circuit and the extension is surge protected, and power to the shed requires switched on before use. Was even thinking of small plumbers pipe with the small blastocyst bolts to secure.

I think I'd just use a bit of plastic conduit, make sure the holes are a tight fit  and hammer it in. can't see it moving anywhere.
or you could put the conduit through, and the insert a bending spring and put a downward 90 bend on each of the ends and then trim the ends to about 50mm, definetely won't come out then

90° bend on both ends with a small clamp, thank you. 👍

It should be little extra effort and cost to run a proper spur with the correct t&e cable from the shed to the summer house. (perhaps a spur off a spur is problematic but better than an extension lead)

Buy a short length of cable, one single or twin socket plus a suitable protective conduit.

Install the conduit. Pass the cable through it and, making sure the power is fully isolated, connect one end to the existing socket and the other end to the new socket.

That will be neater than an extension lead and means that you don't have to go into the shed every time you want power in the summerhouse.

yeah, by all means this is better than and extension lead, but if your power requirements in the summerhouse are less than 13A, just stick with the extension lead in my opinion
