A wood floor electrical box is a must-have for any home renovation project. It's a device that allows you to safely install electrical components, such as outlets and switches, without damaging the surrounding wood floor.
The National Electric Code (NEC) requires that electrical boxes be installed at least 12 inches above the finished floor. This ensures that the box is accessible for maintenance and repairs.
The type of electrical box you need depends on the type of wood floor you have. For example, if you have a hardwood floor, you'll need a box that's specifically designed for hardwood floors.
A standard wood floor electrical box is typically 4 inches square and made of metal or plastic. It's usually installed behind a baseboard or molding to conceal it from view.

Choosing the Right Outlet
The National Electrical Code (NEC) requires floor boxes to be specifically approved and marked for use in a floor. This means you should look for floor box assemblies that are marked by a Nationally Recognized Testing Laboratory, such as UL or CSA.

Approved floor box assemblies will have a metal or plastic outlet box, a receptacle, a gasket, and a cover plate. These components work together to mitigate the entry of water and other debris, which could create a fire hazard.
Floor box assemblies are designed to withstand normal foot traffic, and come in various shapes and sizes, including pop-up options. Recessed floor outlets are less obtrusive and often more aesthetically pleasing.
Don't be tempted to buy separate boxes, receptacles, and covers in an effort to fabricate your own floor receptacle outlets. This would be a violation of the NEC and may result in a fire or life safety hazard.
To ensure you're choosing the right outlet, look for floor box assemblies that are marked by a Nationally Recognized Testing Laboratory.

Installation and Mounting
Installation and Mounting is a crucial step in installing a wood floor electrical box.
First, you'll need to mount the floor outlet box securely to the floor, following the manufacturer's instructions. This ensures a stable and safe installation.

To do this, you may need to chisel shallow notches into the floor to set the box flush. Place the box in the hole and drill pilot holes as needed for any mounting screws.
The circuit will enter the box through a knockout plug, which you'll need to determine and remove. This is usually a round metal plug that's held in place by a screw.
If your box has multiple knockouts, make sure to remove the correct one to avoid any electrical issues.
