Installing A Recessed Floor Socket

As recessed floor sockets come in versions please select the installation instructions for your type of floor socket. Recessed floor sockets are a retrofit product and not cast in place for concrete floors.

Important - always get a qualified electrician to do any electrical work and certify the installation.

Concrete Floors

1 - Cut the hole in the floor

Concrete Based Floors
Cut a hole into the concrete to the depth of the box. The depth varies according to the box type.
Recessed (not concealed flush)
- USB, Shuko, Data & Media - 92mm deep
- Plugs - 72mm deep
Check the depth of the box to be installed before cutting.
Concealed Flush
- All types - 111mm deep less the depth of the floor material so the lid will sit flush with the floor when complete.
Floorboard Floors
Initial Checks
- there is the enough depth under the floorboards to accommodate the socket.
- the cables for the socket in place under the floorboards.
After the checks, cut a hole in the floorboard missing the joists below.
On floorboard floors as the recessed floor socket rests on the flanges on top of the flooring, re-inserting the socket body checks the socket fits in the hole cut.

2 - Hole check - concrete based floors

Insert the body of the recessed floor socket into the hole.

Recessed (not concealed flush)
As these sockets have a flange around the top of the body which will sit over the flooring material. The socket body will sit proud of the floor to allow the floor material to go under the flange. Check this gap matches the flooring material depth.

Concealed Flush
The top of the inlay lid will be raised above the concrete level which will match the floor height when completed. Check the raised height matches the flooring material depth.

3A - Recessed floor sockets (not concealed flush)

Remove the socket body from the hole. As these sockets have a flange around the top of the body which will sit over the flooring material, they are re-inserted after the flooring is laid.
Knock out the cable holes required in the electrical box using a hammer and centre punch to push out the blank, remove completely with pliers if required.
Lay the floor.
Insert the cables through the knock outs and seal holes with grommets to protect cable. If you are using screed this will help prevent the fill screed and debris entering the socket.
If you knock out a blank in the wrong place, use a blank grommet to close the open cable hole.
Reinsert the floor socket into the hole. The flange around the top of the body will sit over the floor.
Secure the recessed floor socket into place using appropriate fixings for the substrate material through the bottom of the electrical box. You may need to install a baton to provide a secure mounting point.
Wire the plug and secure to the recessed socket body.

3B - Concealed Flush recessed floor sockets

Remove the socket body from the hole.
Knock out the cable holes required in the electrical box using a hammer and centre punch to push out the blank, remove completely with pliers if required.
Insert the cables through the knock outs and seal holes with grommets to stop the fill screed and debris entering the socket.

If you knock out a blank in the wrong place, use a blank grommet to close the open cable hole.
Reinsert the body of the recessed floor socket into the hole securing it into place using appropriate fixings for the substrate material through the bottom of the electrical box.
Fill the gaps around the socket and lay the floor.
Wire the plug and secure to the recessed socket body.
Attach the lid to the recessed floor socket body.
Fill the inlay lid with matching flooring.
