The Basics for Installing a Floor Outlet

  • Installing a floor outlet requires a special floor rated outlet box, which is typically a deep metal box.
  • A recessed single or duplex outlet is then installed and a low profile outlet cover which is rated for floor use is then installed.
  • Many of the large hardware stores carry floor outlet kits that come with the box, outlet and the cover.
  • But first of course, the location for the floor outlet will require special planning so that the outlet will be be located in an ideal location, possibly under a table or sofa.
  • This location must not interfere with floor joists or other structural supports or obstacles that may be under the floor.
  • The electrical source may be extended from a wall outlet in the immediate room or area

    Hi Judy,
    If the floor outlet box is cracked it would be best to have an electrician take a look and replace the floor box as needed. This would ensure the electrical components and wiring are safe and prevent any possible complications.
    Thank you for sharing your floor outlet question with us,

  2. Judy says:

    The 220 floor outlet box for our all electric stove is cracked. Last night I pulled out the bottom stove drawer and it dislodged the plug on the floor behind stove. When the plug was put back the stove continues to work as usual. Do I need to replace the floor box? Do I need an electrician to do this?
    Thanks for any help with this.
