In my experience as an electrician, having a 100 amp sub panel with a main breaker is necessary for several reasons.

First and foremost, it allows for better distribution of electricity throughout the house. The main panel typically has a higher amperage capacity and is responsible for supplying power to the entire house. However, if there is a need for additional circuits or appliances, the sub panel can handle the load without overloading the main panel. This ensures that each circuit receives the appropriate amount of power and reduces the risk of tripping breakers or causing electrical fires.

Furthermore, having a 100 amp sub panel with a main breaker provides an extra layer of safety. In case of an electrical emergency, such as a short circuit or overload, the main breaker in the sub panel allows for quick and easy shut off of power to that specific area. This not only helps prevent damage to appliances or wiring, but also minimizes any potential hazards to residents.

Another advantage of having a 100 amp sub panel is increased convenience and flexibility. With more circuits available in the sub panel, homeowners have the option to add new appliances or make changes to their electrical setup without having to constantly modify the main panel. This can save time and money in the long run.

My Buying Guide on ‘100 Amp Sub Panel With Main Breaker’

As a homeowner, I recently had to upgrade my electrical panel to accommodate additional appliances and circuits. After much research and consulting with an electrician, I decided to purchase a 100 amp sub panel with a main breaker. In this buying guide, I will share my experience and provide some important factors to consider when purchasing a 100 amp sub panel with a main breaker.

What is a 100 Amp Sub Panel?

A sub panel is an additional electrical panel that is connected to the main electrical panel in your home. It acts as an extension of the main panel and provides extra circuit space for new appliances or rooms. The 100 amp rating refers to the maximum amount of electricity that can flow through the sub panel at one time.

Why Choose a 100 Amp Sub Panel With Main Breaker?

A main breaker serves as the disconnect switch for the entire sub panel, allowing you to shut off power to all circuits at once in case of an emergency. This is especially important if you are using the sub panel for outdoor areas or separate buildings such as garages or sheds. Additionally, having a dedicated main breaker for the sub-panel ensures that it does not overload and trip the main breaker of your home’s electrical system.

Factors to Consider Before Purchasing

1. Size and Capacity

The size of your sub panel will depend on your specific needs and available space. A 100 amp sub-panel can typically accommodate up to 20-30 circuits, which should be enough for most homes. However, if you have plans for future renovations or additions that may require more circuits, it may be beneficial to opt for a larger size.

2. Brand and Quality

When it comes to electrical equipment, it is crucial to choose reputable brands known for their quality and safety standards. Do some research and read reviews before making your purchase.

3. Type of Breaker

The type of breaker used in the sub-panel can impact its performance and safety. Some common types include thermal-magnetic breakers, which protect against overloads, and ground-fault circuit interrupters (GFCI), which protect against shocks in wet areas like bathrooms or kitchens.

4. Installation Requirements

It is important to consult with a licensed electrician before purchasing a 100 amp sub-panel with main breaker as they will know the specific requirements for installation in your area. They can also advise on any necessary permits or codes that need to be followed.

In Conclusion

Purchasing a 100 amp sub-panel with main breaker can provide added convenience and safety for your home’s electrical system. It is important to consider factors such as size, brand, type of breaker, and installation requirements before making your purchase decision. Consulting with an electrician can also ensure proper installation and peace of mind knowing that your home’s electrical system is up-to-date and safe.
