How to wire a house fuse box

Updated April 17, 2017

Working with electricity can be a tricky process and requires a great deal of caution because of the potential danger involved. The proper wiring of a house fuse box is in itself a safety feature to prevent power surges and potential fire risks throughout your home. Wiring a house fuse box can be done with confidence by following proper and established safety practices. No matter how much you think you know or don't know about electricity and wiring, never take chances during the installation process because the results can be deadly.

  1. Buy a complete fuse box kit at a retail outlet, such as Lowe's Ace Hardware or Home Depot. It's not necessary or even suggested that you construct your on fuse box from scratch. It is important that you purchase the fuse box that is designed for the amount of amperage your home uses. This is going to be based on the size and electric wiring outlay of your home. This amperage can be found on the inside panel of the old fuse box you are replacing.

  2. Disconnect the main power from the electrical power meter. This should shut down the electrical current running to your entire home. If there are any appliances still operating then you have not found the correct shut off switch. Remember, don't take chances, and even if you believe the power is disconnect, still use a voltage meter to insure that the box is truly disconnected before proceeding.

  3. Make sure that you are not in contact with anything wet or damp before removing the old fuse box front panel.

  4. Remove the screws from the inside of the panel to detach it from the box to expose the fuses.

  5. Remove all the fuses in the box.

  6. Disconnect all the wires from each fuse terminal being careful not to fray the ends of the wires.

  7. Attach the wiring running from the various section of your home to the fuse terminals in the new box and then screw the fuses back in.

  8. Turn the main power back on at your electric meter.

  9. Tip

    If available, use a lockout, tag-out system to ensure no one else turns the electricity back on while you are replacing the fuse box.


    Always use standard safety procedures including safety glasses and insulated gloves.
