If your home needs more power, installing a sub panel can help. A sub panel is a smaller electrical panel that connects to your main panel. It gives extra space for circuits. Many homeowners in Appleton choose sub panel installation to add power to their garage, workshop, or new rooms. Let's learn how to install a sub panel step by step.

What is a Sub Panel?

A sub panel is like a small version of your main electrical panel. It connects to the main panel with feeder wires. It gives you extra breaker slots. This helps if your main panel is full. For example, if you build a new garage or finish your basement, a sub panel will give power to that area. Many homeowners choose Sub panel Installation Appleton services to add power safely and keep their electrical system organized.

Why Install a Sub Panel?

Here are some common reasons people choose sub panel installation in Appleton:

No space in the main panel – All breaker slots are full.

Add power to new areas – Garage, workshop, shed, or basement.

Reduce long wire runs – Instead of running many wires from the main panel, a sub panel closer to the new area makes wiring easier.

Better organization – You can keep all circuits for one area in one panel.

Tools and Materials You Need

Before you start, gather these tools and materials:

Sub panel with breakers

Feeder wires (size depends on amperage)

Conduit and connectors

Breaker for main panel

Wire stripper

Screwdriver

Voltage tester

Drill

Always check your local code or consult an electrician before starting.

Plan the Installation

First, decide where you want the sub panel. Common places are the garage, basement, or workshop. Make sure the wall can support the panel. Measure the distance from your main panel. This helps you know how much wire and conduit you need.

Turn Off Power

This is very important. Turn off the main breaker before working. Use a voltage tester to make sure there is no power in the wires. Safety comes first.

Install the Sub Panel

Mount the sub panel on the wall. Use screws to secure it. Make sure it is straight and tight. Leave space around it so you can work easily later.

Run the Feeder Wires

Run feeder wires from the main panel to the sub panel. You need four wires:

  • Two hot wires (black and red)

  • One neutral wire (white)

  • One ground wire (bare copper or green)

The wire size depends on the amperage. For example, for a 60-amp sub panel, use 6-gauge wire. For 100 amps, use 4-gauge. Use conduit to protect the wires, especially if running them outdoors or in a garage.

Connect Wires in the Main Panel

Open your main panel. Install a double-pole breaker for the sub panel. Connect the two hot wires to this breaker. Then, connect the neutral wire to the neutral bus bar. Connect the ground wire to the ground bus bar. Make sure all connections are tight.

Connect Wires in the Sub Panel

Now go to your sub panel. Connect the two hot wires to the main lugs. Connect the neutral wire to the neutral bus bar. Connect the ground wire to the ground bus bar.

Important: In the sub panel, the neutral and ground must be separate. Do not bond them together. If your sub panel has a bonding screw, remove it to keep neutral and ground separate.

Install Breakers in the Sub Panel

Now you can install breakers in the sub panel for your circuits. For example, if you are wiring lights and outlets in your garage, install 15-amp or 20-amp breakers as needed. Connect each circuit wire to the breaker.

Check All Connections

Before turning power back on, check every connection. Make sure wires are tight. Double-check that neutral and ground are separate in the sub panel. Use your voltage tester to confirm no live wires.

Turn On Power

Turn the main breaker back on. Then, turn on the breaker for your sub panel. Check if your sub panel is getting power. Test the breakers in the sub panel to make sure everything works.

Label the Breakers

Finally, label each breaker in your sub panel. This helps you know which breaker controls which circuit. It also helps future electricians or homeowners.

Safety Tips

Always turn off power before working.

If you are not sure about wire size or code, consult a licensed electrician.

Do not overload your sub panel.

Keep neutral and ground separate in the sub panel.
