Electrical panels, also known as breaker panels or distribution boards, are critical components in any electrical system. They manage and distribute electricity safely to various circuits in residential, commercial, and industrial settings. Understanding the different types of electrical panels can help in selecting the right one for your specific needs. Below, we explore the most common types of electrical panels and their applications.
1. Main Breaker Panels
The main breaker panel is the central hub of an electrical system. It houses the main breaker, which can shut off power to the entire building. This type of panel is commonly found in residential and small commercial properties.
- Features:
- Contains a main breaker for overcurrent protection.
- Distributes power to branch circuits.
- Ensures safety by preventing electrical overloads.
- Applications:
- Homes.
- Small offices.
2. Main Lug Panels
Main lug panels do not have a built-in main breaker. Instead, they rely on a separate disconnect located upstream. These panels are often used as subpanels to distribute power to specific areas of a building.
- Features:
- Designed without a main breaker.
- Cost-effective option for specific applications.
- Applications:
- Secondary power distribution in large buildings.
- Detached garages or workshops.
3. Subpanels
Subpanels are smaller panels used to distribute power from the main breaker panel to specific areas of a property. They’re ideal for extending the electrical system without overloading the main panel.
- Features:
- Reduces load on the main breaker panel.
- Provides localized circuit control.
- Applications:
- Large homes with multiple floors.
- Commercial spaces with separate departments.
