Project story

What the work involved

01 · Assessment

The problem

The customer wanted to upgrade an existing standard double electrical socket to a more convenient modern socket with integrated USB-A and USB-C charging outlets. The existing accessory provided two conventional 13A socket outlets but no dedicated USB charging ports, meaning separate plug-in chargers were required for compatible devices. The existing socket and connections were accessed so that the wiring could be checked before the replacement accessory was installed.

02 · Approach

Work completed

Our electrician accessed the existing double socket and removed the faceplate to inspect the wiring and terminal connections within the back box. The existing conductors and connections were checked before the old socket accessory was disconnected and removed. A new switched double socket incorporating integrated USB-A and USB-C charging outlets was then connected to the existing circuit and securely fitted to the wall. Once the replacement was installed, the socket was checked using an electrical socket tester to confirm that the connections were operating correctly. The integrated charging outlet was also demonstrated in use following installation, confirming that the upgraded socket was ready for normal operation.

03 · Result

The outcome

The existing standard double socket was successfully replaced with a modern switched double socket featuring integrated USB-A and USB-C charging outlets. The completed installation provides the customer with two conventional power outlets while also allowing compatible phones and other devices to be charged directly without occupying a socket with a separate USB adaptor. The replacement accessory was secured in position and checked following installation, with the socket tester indicating the expected connection status.

Why upgrade to a socket with USB and USB-C?

Integrated USB charging outlets provide a convenient way to charge compatible devices without using a separate plug-in adaptor. The standard 13A outlets remain available for normal appliances, while the dedicated USB connections can be used for suitable phones, tablets and other low-voltage devices.

Checking the installation after replacement

After replacing an electrical accessory, the connections and operation of the new socket need to be checked. On this job, a socket tester was used following installation to verify the connection status before the socket was put back into normal use.

Frequently asked questions

Can a normal double socket be replaced with a USB socket?

In many installations, an existing double socket can be replaced with a compatible socket incorporating USB charging outlets, provided the existing wiring, back box and circuit are suitable. An electrician should assess the installation before replacement.

What is the benefit of a USB-C wall socket?

A socket with an integrated USB-C outlet allows compatible devices to be charged directly from the wall accessory without requiring a separate plug-in USB adaptor.

Do the normal plug sockets still work with a USB socket?

Yes. The replacement used on this job retains two conventional switched 13A power outlets in addition to the integrated USB-A and USB-C charging connections.

Does a replacement socket need to be tested?

Electrical connections should be checked after replacement to confirm that the new accessory has been connected and is operating correctly. The appropriate checks depend on the work and the existing installation.
