Proper electrical panel wiring is crucial to the long term accessibility and resale value of your home. Not only does adequate wiring allow you the freedom to utilize a wide range of electronics and electrical devices immediately, but it prepares your home for future demands and changes in technology or your own personal preferences. A home with excellent wiring is more likely to meet the demands of a purchaser or appraiser in years to come. Follow these steps to set up electrical panel wiring in your own home.

Step 1 - Map Out Your Home

If you haven't already, select a proper location for your electrical panel. Choose a site where it is least likely to be disturbed, such as a closet or basement. Because each of the wires for your electrical power source will begin at the electrical panel, it is wise to consider exactly how you will route the wires through your home before setting up the panel itself. Make sure that you notate where any switches, outlets and other devices will be located.

Step 2 - Shut Off Power

This is perhaps the most crucial step of any electrical project, and can save you from serious injury or death by electrocution. Before beginning any work on the electrical wiring of your home, turn off the power to the circuit that you will be working on. Removing the fuse or tripping the circuit breaker are both ways of doing this. Before you continue any further, use a neon tester to make absolutely sure that there is no electrical power flowing.

Step 3 - Mount Your Electrical Panel

Follow the manufacturer's installation instructions to mount the electrical panel on the wall. Choose a protected location that is high up or otherwise out of reach. Use the screwdriver or another mounting tool to attach the panel firmly to the site of installation.

Step 4 - Route Your Wires from the Panel

Whether you are working from an unwired home or are simply installing a new electrical panel, bring all of the wires that you plan to install to the electrical panel. If you wish, you may route the wires through the home completely at this point, mounting them along studs and setting them up at switches and outlets. However, if you are just interested in connecting them to the electrical panel itself, simply ensure that you have the ends of each wire at the panel.

Step 5 - Match the Wires

Connect the wires at the panel according to the panel instructions, being careful to match every wire with its connector properly.

Electrical wiring of any kind is exceedingly dangerous, and it is not wise to attempt any work of this kind unless you have prior electrical experience or the assistance of a professional. Before attempting any wiring at home, ensure that you take all necessary safety precautions and that the power is completely deactivated.
