Electraline300180 Waterproof Protective Box for Outdoor Electrical Connections Weatherproof IP54 with 5 Cable Outlets (from 7.5 mm to 12.4 mm), Dimensions 390 x 228 x 138 mm, Green, Empty X-Large

I wanted as big a box as I could find and this fit the bill. It is easy to open and close and the cable holes take even quite thick power leads. As you can see from the picture it holds a four socket extension with two RCD plugs and still closes easily

Excellent ideal for my pond and outside use does not let water in better than outdoor sockets more secure.

This really is a great well designed outdoor box. There are several holes for different cable sizes and clamps to stop the cables moving. There are cable tie holes to secure a 4 way power adapter to the box and mount holes at the back to allow it to be mounted to bottom of a fence upright. I was so impressed with the first box that I bought a second one for the other side of the garden.

This was placed above a bay window roof , under the main roof overhang containing a 20amp 12V PSU and a raspi-pi which was controlling my 600 led xmas pixel led strip around the front of the house

Kept cables safe & dry

This box was perfect for installing all my fish pond electrics really pleased with this purchase. 😀

Bought mine to protect my EV Granny charger and the socket end of a high power mains extension lead when I needed to use it on camping trips, visiting family etc. It's perfect for that, plus it is just big enough to store the granny charger and the permanently attached leads, so bonus.

Not bad but not big enough for what i needed
