How to Install an Electrical Floor Outlet in Brick

In modern homes with open floor plans, a floor outlet is often needed to supply electrical power for lighting or audio-visual electronics. Some companies have risen to this challenge by inventing a self-contained electrical floor outlet in a long cylinder that you can install simply and effectively yourself, even into a brick floor. Follow the directions below to install an electrical floor outlet through a brick floor surface.

Install the floor outlet under a table for a lamp, or near your computer desk to prevent wires snaking all over the floor. The floor outlet units come with various cover plates to use with standard 3-pronged electrical plugs, or with communications wiring such as USB or phone jacks. Turn off power to the area either with the circuit breaker or by shutting off the circuit box completely.

Find the wiring under the floor to connect to the new outlet and prepare it for connection, as directed in the outlet cylinder kit.

Using the 115-mm diamond hole cutter saw, cut through the brick and the supporting floor structure to make the hole for the outlet cylinder.

Sand the edges of the cut and use the power masonry sander to smooth the brick surface 1 inch outward around the hole. This will facilitate a snug, smooth fit between the brick floor surface and the brass flange and cover plate of the outlet cylinder.

Detach the cover plate at the bottom of the outlet cylinder. Connect the incoming power lines to the ground, black and white, pre-stripped wires in the cylinder, and fasten them with the wire connectors provided. Tuck all the wires inside the bottom of the outlet cylinder, and clamp the incoming power wiring under the attached cable clamp. Secure the outer cover plate to the cylinder base with the 2 brass screws provided.

Push the outlet cylinder box up through the hole in the floor to the surface. Insert the cover plate desired and fasten it to the top lip of the outlet cylinder. Slip the brass flange plate over the gasket edge of the cover plate. Drill 2 bolt holes 1 inch deep into the brick. Fasten the outlet cylinder to the brick floor with its brass screws. Restore electrical power.

Plug your device into the outlet to ensure it functions. If not, turn off the electrical power and check the wiring against the kit diagram provided with the outlet cylinder.

Once you have installed a floor outlet cylinder, you may want more all over the house.
