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.

For any electrical works around your home, it is always best to seek the services of an electrician, especially when installing service boards. If a 100 amp panel is a subpanel, the panel will have isolated ground and neutrals with the bonding strap removed.

Most contemporary homes have what is now commonly referred to as an electrical panel or the service panel.
