If you’re looking to install a 125 amp sub panel in your home, you’ll need to prepare for the wiring process. The sub panel will allow you to distribute electrical power to different areas of your home safely while avoiding overloading the main panel. This article will guide you through the wiring process, from start to finish.
What You’ll Need
Before you get started with the wiring process, you’ll need to gather the following materials:
| Materials | Tools |
|---|---|
| – 125 amp sub panel box – Circuit breakers – Grounding rod – Grounding wire – Neutral wire – Hot wire |
– Wire strippers – Screwdrivers – Pliers – Electrical tape – Voltage tester – Drill – Hammer |
Step 1: Turn off the Power
Before you start the wiring process, you must first turn off the main power to your home. This will prevent any accidents or dangerous situations from happening while you’re working with electricity.
Use a voltage tester to make sure that the power is off before starting the installation process.
Step 2: Mount the Sub Panel Box
Mount the sub panel box at least 12 inches from the ground in a well-ventilated area. Make sure that the location of the sub panel is easy to access and isn’t obstructed by any objects.
Use a drill to create holes in the sub panel box and the wall. Use a hammer to insert anchors into the holes and secure the sub panel box in place.
Step 3: Run the Wires
Run the hot wire, neutral wire, and grounding wire from the main panel to the sub panel box.
Use wire strippers to remove the insulation from the ends of the wires. Connect the wires to the corresponding terminals in the sub panel box.
Step 4: Install the Circuit Breakers
Install the circuit breakers in the sub panel box. Make sure that the amperage of each circuit breaker corresponds to the amperage of the wires you’re using.
Connect the circuit breakers to the hot wire and neutral wire in the sub panel box.
Step 5: Install the Grounding Rod
Drive the grounding rod into the ground near the sub panel box. Connect the grounding wire to the grounding rod and the grounding terminal in the sub panel box.
