FAQs

Can I use this for outdoor work?

This unit is designed for indoor use in dry environments like sheds or garages. It is not weatherproof or IP-rated for outdoor exposure.

What type of cable should I use?

Use a 3-core 1.5mm² flexible mains cable rated for 13A for the best safety and performance.

Is this socket fused?

The socket itself is a distribution point; the circuit should be protected by the fuse in the plug attached to the other end of your custom cable.

Does this include a mounting back box?

No, this item is supplied as the socket unit only. You will need to purchase a compatible surface-mount box separately if you intend to fix it to a wall.

What tools are needed for assembly?

You will need a wire stripper, a flat-head or Phillips screwdriver for the terminal screws, and a utility knife to cut the cable insulation.

Troubleshooting

Socket does not provide power after wiring

Verify that all wires are securely fastened to the correct terminals and check that the fuse in the plug at the other end of the cable is functional.

Cable slips inside the socket

Open the unit and further tighten the integrated cable grip screws to ensure the cable sheath is firmly held in place.

Setup, Compatibility & Care

To assemble, you will need a 13A BS 1363 fused plug and an appropriate length of 3-core mains cable. Open the socket casing, thread the cable through the integrated cable grip, and secure the live (brown), neutral (blue), and earth (green/yellow) wires to their respective terminals. Ensure the cable grip is tightened firmly over the cable sheath. Regularly inspect the internal connections and the cable grip annually, especially if the unit is subjected to frequent movement. Keep the socket away from moisture and avoid overloading beyond the 13A threshold.
