How To Wire a 240V Outlet for Appliances

Lay Out the Outlet Box

• Use a stud finder to find and avoid studs in your walls.
  • Alternatively, start at a corner or door jamb and measure 16 inches over.
  • If you don’t find a stud at 16 inches, try 24 inches.
• Hold the electrical box level on the wall at the height you’d like your dryer outlet, avoiding the stud by two inches.
• Put painters tape on wall before outlining, in case you make a mistake or want to move locations.
• Trace the outline of the front of the box onto the wall/painters tape with a pencil.
  • Hold a level on the box as you trace so your finished outlet won’t be crooked.
  • If you can’t get your pencil around the whole outline, make several marks around the perimeter and connect the lines with a level.
