FAQs:

Q: What is the difference between a Main Breaker load center, and a Main Lug load center?

A: A Main Breaker load center comes with a factory installed main breaker and provides over- current protection for the entire load center, as well as a single means of disconnect for the entire house.

A Main Lug load center, also known as a sub-feed load center, comes with no main breaker factory installed.

Q: When would a Main Breaker load center be used?

A: Main Breaker load centers are typically used for new construction, replacement of an existing main breaker load center, or where service is being upgraded – for example, from 100A service to 200A service.

Q: When would a Main Lug load center be used?

A: Main Lug load centers are typically used as an “add-on” load center to the main breaker load center, when additional circuits are desired and there are no more spaces in the main breaker load center for the additional circuits. It may also be used to distribute power to select circuits, from a more convenient location in the home.

Q: Load centers come in different sizes. How do I know which one to use?

A: The size of load center to use is usually a function of the size of the house, and how the electrical load is distributed throughout the house. Generally, the larger the house, the more  amps will be needed, and so a larger load center will be needed. Similarly, the more circuits the electrical load in the house is distributed to, a larger load center will be needed.

Q: Can load centers be used Indoors & Outdoors?

A: Yes. There are load centers designed specifically for Indoor applications, and loadcenters designed specifically for Outdoor applications. Be sure to understand where the load center is to be installed to select the correct load center.

List examples of projects that would require this product:

1. Main Breaker load centers for new home construction, or service upgrade

2. Main lug load centers for add-on’ circuits when space in an existing loadcenter is limited, or when a more convenient location for certain circuits is desired.
