FAQS on 100 amp panel

Q: What is the difference between a 100 amp panel and a 150 amp main breaker outdoor panel?

A: A 100 amp panel supports up to 100 amps of electrical load, while a 150 amp main breaker outdoor panel provides higher capacity and includes an integrated main circuit breaker. The 150 amp panel is weatherproof and designed for exterior installation, making it ideal for homes requiring more power.

Q: Can a 100 amp main lug panel be upgraded to include a main breaker?

A: No, a 100 amp main lug panel lacks a built-in main breaker and cannot be retrofitted with one. To add overcurrent protection, you would need to install an external disconnect or replace the panel with a main breaker model.

Q: Is a 100 amp panel sufficient for a modern household?

A: A 100 amp panel may suffice for smaller homes without high-power appliances, but larger homes with electric heating, EV chargers, or multiple AC units often require a 150 amp or higher panel for safe, reliable operation.

Q: What are the advantages of a 150 amp main breaker outdoor panel?

A: A 150 amp main breaker outdoor panel combines higher capacity with weather-resistant construction and integrated overcurrent protection. It simplifies installation by eliminating the need for a separate disconnect and supports heavy-duty electrical demands.

Q: Can I use a 100 amp panel as a subpanel for a 150 amp main breaker panel?

A: Yes, a 100 amp panel can serve as a subpanel if connected to a 150 amp main breaker panel via appropriately sized wiring. Ensure the subpanel's amperage rating aligns with the circuit load and local electrical codes.
