How to Safely Wire Your Home Without Any Electrical Experience


Wiring a home can seem like an intimidating task, especially if you don't have any prior electrical experience. However, with the right precautions and preparations, even beginners can safely wire lighting, switches, and outlets in their home. In this comprehensive guide, I'll walk through all the key steps to follow for safely wiring a home without experience.

Gather the Right Supplies

Before getting started, you'll need to stock up on some basic electrical supplies:

Be sure to get the proper wire gauge for the circuits you'll be working on. For 15 amp general lighting circuits, 14/2 cable with ground is commonly used. For 20 amp kitchen, laundry, and bathroom circuits, use 12/2 cable with ground.

Turn Off Power and Check Wires

Before doing any wiring work, you must first turn off the power at the main circuit breaker panel. Test wires with a voltage tester to make sure power is off. Remember to check that the power is not just locally turned off, but shut off at the main panel.

Plan Your Wiring Layout

Carefully consider where you want switches, lights, and outlets placed. Having a wiring plan minimizes mistakes and saves time. Draw a simple diagram of the wiring layout to use as a reference. Group together circuits that will share the same path through walls, attics, and basements.

Run Cables and Conduit

With the power off, you can start routing new cables between the fixtures and outlet boxes and back to the main panel. Follow these tips:

Leave plenty of extra wire at each box for making connections.

Connect Switches and Outlets

At each switch and outlet box, carefully strip off about 1/2 inch of the outer plastic sheathing from the cable using wire strippers. Be careful not to nick the inner wires.

Wire connections can be made as follows:

Securely twist wires together with wire nuts and wrap each connection with electrical tape. Follow diagrams on the switch/outlet closely.

Connect Lights and Appliances

At each light fixture, fan, or appliance, make connections from the wiring cables to the unit. Most lights and fans have push-in or screw terminals, along with a ground wire. Appliances have a terminal block or leads to connect hot and neutral wires.

Again, be sure to securely fasten each wired connection and wrap with electrical tape. Don't forget the ground wire.

Inspect and Test

With all wiring connections made, carefully inspect each one before restoring power. Look for:

Once inspected, turn on the power and test operation of lights, fans, and outlets. Check for proper function, and make any wiring corrections needed.

Safety Tips

When working on home electrical wiring, be sure to follow these important safety practices:

When to Call an Electrician

While many basic wiring projects can be DIY, when in doubt, call a licensed electrician. Seek professional help for:

Paying an electrician is worthwhile to ensure safety for large and complicated electrical work.


With good planning and by following basic electrical safety procedures, even novice DIYers can successfully wire lighting, switches, and outlets in their homes. Just take it slowly, double-check your connections, and seek help from experts when needed. Thoroughly researching the project ahead of time will also set you up for success. With the right diligence, you can wire your home's electrical system safely without experience.
