What are floor boxes?

Floor boxes are a type of electrical box that is installed in the floor. They are used to provide power and/or data connections to devices in a room or space. Floor boxes come in a variety of styles and sizes, and can be installed in new construction or retrofitted into an existing floor.

Floor boxes provide a convenient and accessible way to power and connect devices in a room or space. They are especially useful in areas where there is limited wall space, such as in a kitchen, bathroom or offices. Floor boxes also make it easy to change or add electrical devices, without having to mess with wires or cables.

Floor Box Options

There are a variety of floor boxes available, including:

Single-gang: These boxes have one electrical outlet and are typically used to power small appliances or devices.

Double-gang: These boxes have two electrical outlets and are typically used to power larger appliances or devices.

Data: These boxes have a data connector and are used to provide internet or network connections in a room or space.

Combination: These boxes have both an electrical outlet and a data connector, and can be used to power and connect devices simultaneously.


There is a range of heavy-duty floor boxes available that are specifically designed for specialist areas. For example, there is a range of waterproof and dustproof floor boxes that protect the inner box from outside elements. These are commonly found in areas such as shopping malls, convention centres, museums, airports and on the streets. These areas are regularly exposed to dust, grime and are regularly washed down.


Installing a floor box is fairly straight forward. First, open the floor. If you are working with a false floor, you will need to cut the floor box into a floor tile. Make sure to keep the floor box towards the centre of the tile so you don’t weaken the tile by cutting too close to the edge. However, offsetting the box within the tile allows for greater adjustment when moving the tiles into place to fit your desk layout.

Now, measure and mark where you want the floor box to go. In most cases, it is best to put it near an outlet. Drill a hole in the floor that is slightly larger than the floor box. Insert the floor box and secure it in place with the screws that come with the box. Close the floor and enjoy your new electrical outlet!

How are floor boxes wired?

Floor boxes are usually wired using Romex cable. This is a type of cable that has two insulated wires and a ground wire. The ground wire is required in order to properly ground the floor box.

When wiring a floor box, it is important to make sure that the circuit breaker for the outlet is turned off. Then, connect the black wire to the brass terminal screw and the white wire to the silver terminal screw. Finally, connect the ground wire to the green ground screw. Tighten all of the screws securely and re-attach the cover plate. Turn on the circuit breaker and test the new outlet.

Are Electrical floor boxes safe? Yes, floor boxes are safe to use. They must be properly grounded in order to reduce the risk of electrical shock. Floor boxes are also designed with a cover plate that helps to protect against accidental contact with the live wires inside. Always make sure to turn off the circuit breaker before working on wiring and to follow all safety precautions.
