Looking to buy a waterproof junction box to join some 4mm armoured cable for a power supply outside which will ultimately run into a couple of sheds.

Seen a few in Screwfix/Toolstation/B&Q etc but as always like to get recommendations.

Don't ask me anything technical I did well to disconnect the supply and move it out of the old shed I demolished without blowing myself up!!!

Make sure it's IP66 rated. How will you be connecting inside the box? Will it be 32A max rating?

I know you said nothing technical, but these are the minimal basics you should know before you start connecting up 4mm mains cable.

I haven't worked with armoured cables for years however...4mm cable is a bitch to work with so opting for a larger sized junction box would be something to consider.
Have you also got suitable glands and are you able to make them off ok?

I'll get glands when I get a junction box.

The "complaint" with the waterproof junction box at Screwfix is that it's a bit too big, maybe I'll just buy that then? It was more a post to see if anyone had used any of the "brand" ones and would recommend one over the other!

i use these for all my electrical requirements TLC Direct
Forget your DIY chains:)

Edit..perhaps this might be of use?..32a junction box, IP66 rated
I used simular though lower amp rating for when I redid all my outside security lights with armoured cable. You will need the screw in sealed cable clamps, and I also put stopper caps on the unused entrance points even though the rubber membrane was intact:)

Simple answer, no. Brands are much a muchness in my opinion. Its the rating that's more important.
How will you connect up the junction? 4mm cable is hard to bend in to position so a larger box with some Wago 42A connectors would be my method.

If the box is going to be outside get this from ip66 box Screwfix cat No 17308, 150 x 150 x 80 you'll have 3 cables so you need enough room inside to make off the joints.
Can't you re-route the cable so it's inside hut 1 then loop across to hut 2, a galvanised Screwfix box 17308 would then do, you'll need a 32 amp connector strip.
Make sure the circuit is RCD protected.
Remember red to brown, green to yellow and green stripe, and blue to kingdom come.
