This article provides a step-by-step guide to safely rewiring outlets in your home to handle more power, without creating fire hazards.

Determine if Your Home's Electrical System Can Handle More Load

Before making any changes, it's critical to understand the current capacity of your home's electrical system. Here are some key steps:

Calculate Total Power Draw of Devices

Identify Size of Existing Wiring and Breaker Capacity

Consult an Electrician if Unsure

Upgrade the Electrical Service Panel if Needed

If your existing wiring and breaker amperage are insufficient, a service panel upgrade is required for safely adding more outlets. Key steps include:

Though expensive, a new service panel is essential to add circuits and outlets without creating fire and electrocution hazards. Never overload an underrated system.

Add New Circuits and Wiring

With adequate service capacity, you can add new 120V household circuits to supply additional outlets.

Determine Locations for New Outlets

Pull and Connect New Wiring

Install GFCI Outlets Near Water Sources

Label Breakers Clearly

Use High-Capacity Devices and Wiring for 240V Circuits

For large appliances requiring 240V power like electric dryers or AC condenser units, utilize heavier gauge wiring and higher amperage double-pole breakers.
