FAQs

What type of plug can I use with this socket?

This is a 5A unswitched round pin socket. You can only use plugs with two round pins, typically found on items like shavers or some low-power lighting fixtures. It is *not* compatible with standard UK 13A rectangular pin plugs.

Is this socket switched?

No, this is an unswitched socket. This means it provides continuous power when the circuit is live and does not have an on/off switch on the unit itself.

What are the dimensions of the socket?

The dimensions are 86mm wide x 86mm high x 7mm deep (excluding the back box).

What does 'anti-microbial properties' mean?

The plastic material used in the socket has been treated to inhibit the growth of bacteria and other microorganisms on its surface, contributing to a more hygienic environment.

What is the maximum wire size that can be terminated?

The terminal capacity supports up to 2 x 1.0mm², 2 x 1.5mm², or 1 x 2.5mm² conductors.

Do I need a special back box?

You need a back box with a minimum depth of 25mm for installation.

Is this product suitable for outdoor use?

No, this socket is IP20 rated, which means it is designed for indoor use only and offers protection against solid objects but not water ingress.

Troubleshooting

Socket not providing power

Check that the circuit breaker or fuse is on. Verify wiring connections are secure and correct. Ensure the connected device has a 5A round pin plug and is functioning.

Loose socket plate

Tighten the mounting screws securing the socket to the back box. Ensure the back box itself is firmly installed in the wall.

Poor connection with plug

Ensure the plug being used is a 5A round pin type and is inserted correctly. Inspect the plug and socket for any debris or damage.
