4. Cost-Effective: Purchasing a meter main combo can often be less expensive than buying separate meter sockets and breakers.
5. Versatile Configurations: Options are available for various amperage ratings and configurations, making them suitable for different applications.

How to Choose the Right Meter Main Combo

Choosing the correct meter main combo involves several considerations:

1. Determine Your Amperage Needs

• Assess the electrical load requirements of your home or building.
• Common options include 100A, 150A, 200A, and 400A.

2. Select the Configuration

• Decide between different configurations based on the number of circuits required.
• Options can range from simple 4-space units to more complex 20-space designs.

3. Consider the NEMA Rating

• Choose a NEMA rating based on the environmental conditions where the unit will be installed.
• NEMA 3R is common for outdoor installations, providing protection against rain and snow.

4. Evaluate Special Features

• Look for models with features like solar readiness, lever bypass options, and horn bypass configurations.
• Some models may include a 5th jaw for additional circuit needs.

5. Check for Compliance

• Ensure the product meets local electrical codes and regulations, including NEC compliance.

User Tips for Meter Main Combos

• Consult a Professional: If you’re unsure about your electrical needs, consult a licensed electrician to assist in selecting and installing the appropriate unit.
