How to Wire a House Fuse Panel for a Range or Dryer
Bought a new electric range or dryer for your home, did you? Now, you need to have it professionally installed. Or do you? Maybe you'd like to do that yourself. You'll need new 220V electrical service to go with your new range or dryer. Here's what you need to know to wire a house fuse panel for a range or dryer.
Buy enough #4 AWG-4 strand cable to run from your new Buss bar fuse box location, up to your attic, across the attic and down the wall to where you want to install your new range. Measure the distance and include a little extra so you can also hook up your electric service to the new box. A dryer may only need 12ga-3 wire insulated cable; check your local building codes. Purchase a new Buss fuse and fuse Buss bar set and mount it in a new box that is rated, and set up for, a 70 amp Buss fused circuit for a new range, or a 30 amp, double fuse circuit set, for a new dryer.
Decide where you will install your new appliance. Cut a hole in the wall with the key hole saw. This is where you will be installing your electrical box next to a wall stud, inside your wall. If you have an older home with lathe and plaster walls, and you want to install a new range, run your wire as a surface mount by using conduit from the ceiling down to the installation point behind the appliance. For the laundry room, even with a stud wall, run your wire as a surface mount, down to the point where you will install your new dryer. Do the same thing next to where you will be installing your new fuse or fuse breaker box. Run your wire from the attic, down to each point; to the new appliance and to the new service wiring box. This will be placed next to your existing electrical fuse box.
Set these two boxes up, together, by mounting them, side by side, but don't connect them yet. First connect the appliance outlet in or to the wall. This is the one that you bought to match the requirements of your new appliance. Wire your cord to your new appliance and plug it in to your new outlet, but don't turn anything on just yet.
Go to your old fuse box and remove the cover. This allows you access so you can connect the two boxes together with 220V from your current house power. Your house power is what powers your new appliance too. Connect the two boxes together using the #4AWG wire left over from your new wiring. Do this with the new fuse panel empty of fuses and the power shut off to both boxes so no power can accidentally pass through either box.
Put everything back together and turn the power back on, but DO NOT install a fuse or fuses in the new box, just yet. Check your work to assure everything is connected, covered or cleaned up.
Test it. Turn it on. Connect the power to your appliance by unstalling the fuse/fuses and turning it on.
- Because it is considered safer, connect to house power after all the new wiring is installed. Since this is a home project, with you in control, you make that decision. Just do the job safely with all electrical power to your work area, shut off.
