Note that a circuit breaker panel is not the same as a fuse box because it has mechanical, toggle-switch individual circuit breakers, not fuses, but it does perform the same function just in a safer manner. Therefore, a service panel is the distribution point that connects the incoming main service wires (service drop) to the exit wires(branch wire circuits), which branch off to distribute electricity to different parts of the house. A subpanel is not bonded but has two hot wires, one neutral wire, and a bare copper wire for grounding. It is always good to know that the main service panel has the main disconnect.Īlso, the main service panel is bonded. Often, you will find a single circuit breaker at the meter, which is the main breaker (service disconnect), and one or more remote distribution subpanels inside the house.ĭepending on the electrical panel installation, you may find the main service panel and disconnect circuit breaker either on the top or bottom, depending on whether the service wire feeds from overhead or underground.

Today, most builders install the main disconnect outside (the main panel) and the distribution panel ( subpanel) inside the house or garage. In older homes, you may find the main service disconnect and the breaker together.

The Distribution Panel is the circuit breaker panel with the entire circuit load that may be inside, possibly in the garage.

The Main Panel, which is the main disconnect breaker, 100 amps in this case is the Service Panel.

When we talk of an electrical service panel, two things come up

His job is to configure the route the cables will take toward the breaker sub-panel. An electrician can accomplish this by adding 2-pole individual breakers or tandem breakers to allow two circuits to share a single 110v breaker slot safely. If there is none available, the electrician could pigtail the branch circuit wires and breakers to provide the extra space. To add a breaker sub panel to a service panel, the electrician should install the 100 amp main breaker across two breaker slots. Aluminum is often used for service entry wires because it’s much cheaper than copper, lightweight, and easy to work with despite copper being a better conductor. Wire sizes are identified in American Wire Guage (AWG) and contain copper or aluminum wires in a wide array of thicknesses.Ī 100 amp subpanel installation requires #4 AWG copper wire or an equivalent of #2 AWG aluminum wires.

Installing A 100 Amp Service PanelĪ 100 amp circuit breaker is enough to power a condo or, to be more precise, a two-bedroomed apartment.įor larger homes with a 200 amp breaker box or higher that need more voltage, you can add a 100 amp subpanel. In comparison, the only minor difference between a 100 amp and the 200 amp panels could probably be the sizing of the main circuit breakers and the thickness of the wire cables used to connect the meter box to the breaker box.
