How to Rewire Your Outlets for More Power Without an Electrician

Introduction

Upgrading the electrical wiring in your home can provide more power to outlets and allow you to run more devices and appliances. Rewiring outlets yourself is a complex project but can save on electrician fees if done safely. This guide will walk you through the complete process of rewiring outlets step-by-step without professional help.

Reasons to Rewire Outlets

There are several benefits to rewiring electrical outlets in your home:

Insufficient Power

• Older homes often have outdated wiring that cannot provide enough electricity for modern devices and appliances.
• Rewiring outlets can provide the increased electrical load capacity needed.

Grounding

• Ungrounded outlets are outdated and potentially unsafe.
• Rewiring with grounded cables adds protection from shocks and fires.

Convenience

• Adding more outlets eliminates the need for extension cords.
• Rewiring allows you to place outlets exactly where you need them.

Dangers of Rewiring Outlets

While rewiring outlets can be rewarding, it also comes with risks:

• Contact with live wires can result in severe shock or electrocution.
• Faulty wiring can lead to electrical fires.
• Mistakes can damage appliances and electronics.

Working on electrical wiring without proper precautions and training can be extremely hazardous. Make sure you understand the risks before attempting a rewiring project yourself.

Preparing to Rewire

Completing the project safely requires gathering the right tools and materials:

• Voltage tester - To safely check wires are de-energized
• Electrical tape - For insulating wires
• Wire strippers - For accessing wire inside cables
• Cable ripper - To remove old cables from walls
• Fish tape - To route new cables through walls
• Replacement cables - Use the correct size and type for your home's electrical system
• Replacement outlets - Grounded is recommended for safety

You will also need to turn off power at the main circuit breaker panel and verify it is off with a voltage tester before working on any outlets.

Removing Old Outlets

The first step is accessing the wiring behind existing outlets:

1. Unscrew the outlet cover plate and remove it.
2. Unscrew the outlet from the electrical box and pull it out.
3. Carefully unscrew the cables from the outlet and detach them.
4. Use a cable ripper to strip the sheathing off the cables inside the wall cavity.
5. Pull the cables out of the box so they are accessible.

With the wiring exposed, you can now install new cables.

Running New Outlet Cables

There are two methods for routing new wires depending on your home's construction:

Through Wall Cavities

For framed walls with open cavities:

• Drill access holes near the floor and ceiling.
• Use fish tape to route new cables down from the attic and up from the basement or crawlspace.

Behind Drywall

For solid walls without cavities:

• Cut narrow channels behind the drywall to route cables.
• Stagger access points to minimize drywall patching.
• Use flat cables that fit neatly into channels.

Carefully plan the cable routing to cover all outlet locations efficiently.

Connecting Outlet Wires

With the new cables in place, you can now make connections:

1. Strip 1/2" of insulation from each wire end using wire strippers.
2. Attach the ground wires from the outlet and cable using a wire nut.
3. Connect the white (neutral) and black (hot) wires the same way.
4. Wrap each connection tightly with electrical tape for insulation.
5. Coil excess wire neatly in the outlet box to minimize clutter.

Follow the same process to wire all outlets in the circuit.

Installing New Outlets and Covers

You're now ready to complete the upgrade:

• Place each rewired outlet back into its box.
• Screw the outlet firmly into place.
• Replace the outlet cover plate.
• Once all connections are made, restore power and test each outlet.
• Replace drywall and refinish any repair work needed.

Take your time and be meticulous to ensure safe and lasting results.

Rewiring Precautions

To keep yourself and your home safe, be sure to take these additional precautions:

• Turn off power at the breaker before starting and verify it is off.
• Only work on small sections of wiring at once to avoid confusion.
• Label all wires so you can keep track of their connections.
• Check local building codes for any regulations on outlet wiring.
• Hire an electrician if you have any doubts about doing the work safely.

Conclusion

Rewiring outlets is a worthwhile upgrade for added convenience and safety when you need more power. Just be sure to carefully plan the project and take all necessary electrical precautions. If done properly, rewiring your own outlets can pay off for years to come. Let me know if you have any other questions!
