A really dumb question about wiring an extra plug socket.

[Efour]

Swedish electrical regs are very strict and I'm not attempting this, roll eyes, but am I crazy in even worrying about this not being feasible.

I have a surface mounted 3 core wire running to an external set of plugs in an outbuilding.

I want to add another plug along the line to plug in a WiFi extender.

Can I simply cut the wire, connect the internals through the top ip44 grommet thing and do the same with the bottom half of cut wire in the bottom grommet thing. ? I know that's not rocket science.

Or is it more proper safer to cut the wire add a small junction box then run a very small wire over to the new socket.

Solution 1 is probably not advised but it's much less messy I literally just want the. 1 plug where it is, as little extra mounted furniture stuff as possible.

Help

Ok so the word I'm looking for is spur....

Thanks I'll read up in English first then take it to the Swedish rules.

Yep there's no way i can legally do this so must contact an electrician or rethink what i can actually do :/
Wish i trained as an electrician, wonder if theres any even classes that will qualify me at a basic level.

thanks for the help.
