What is the difference between a main breaker and a main lug?

What is the difference between a main breaker and a main lug?

The main circuit breaker provides a level of overcurrent protection for all branch circuits, as well as a single disconnect means for all loads being fed by the load center. Main lug only load centers are typically applied downstream of a main circuit breaker panel and are often referred to as a sub panel.

What are electrical panel lugs?

Main lug units are primarily used as a distribution panel where there is a main breaker upstream in the system. These panels are added when all circuit slots in the main breaker load center are full or when a remote panel is desired.

What is a feed through lug?

Feed-thru lugs: 1. Always mounted opposite of the main. 2. Used on main lug or main breaker panels.

What is a sub panel?

A subpanel is a smaller service panel that distributes power to a specific area of the home or other buildings on the property. It is essentially a satellite circuit breaker panel that has its own breakers.

Does a main lug need a main breaker?

Main lug panels do not have a main breaker. Instead, the line wires run to a type of electrical connector called a lug. This type of electrical panel requires a separate disconnect.

Can I use a main lug panel as a main breaker panel?

Yes, you can put a main breaker panel where a MLO panel used to be assuming this is for “replacement” purpose only. Your inspector or power company may have an issue with doing a partial service change on a 60A fused service though so you will need to check with them first.

What does Main lug panel mean?

Main Lug Panels. Main lug panels do not have a main breaker. Instead, the line wires run to a type of electrical connector called a lug. This type of electrical panel requires a separate disconnect. In the event of a fire, the separate disconnect at a meter lets firefighters cut the power without entering the buidling.

Does a subpanel need a main disconnect?

The subpanel may be equipped with a main breaker to allow for power interruption without having to go back to the main panel, but it is not required to have a main shutoff circuit breaker, since the feeder breaker back in the main panel serves this function.

What is the difference between a panel and a sub panel?

The real difference between a subpanel and main panel is where the wires of system lead and the power of volts it provides. For instance, subpanels can give off 30 amp, which is about 240 volts of electricity. Subpanels don’t add energy but feed off the electrical current of your main service panel.

What is the difference between the 3-lug Mount and the 9mm Mount?
