What are the different types of breaker boxes?
There are three basic circuit breaker varieties: standard breakers (which include both single-pole and double-pole circuit breakers), ground fault circuit interrupter circuit breakers (GFCIs) and arc fault circuit interrupter circuit breakers (AFCIs).
What is the difference between breaker box and subpanel?
A main panel is an installed box where the power from the utility company enters the premises. A subpanel is an installed features that acts as a middle ground for the main panel and other types of circuits that are connected to your property.

The amount of current that is required for the connected loads can only be supported by a 30 Amp sub-panel. The maximum quantity of branch circuits can be determined with a load calculation. Two 15amp breakers or one 15amp and one 20amp can be used on a 30amp circuit.
Does my house need a subpanel?
If your home’s electrical service panel (breaker box) is full and you need more room to add new circuits, installing a subpanel might be the way to go.

How much does it cost to install a subpanel?
between $400 and $1,750
The average cost of installing a subpanel is between $400 and $1,750, depending on the amperage and number of circuits installed. Typically subpanels have 4 to 20 or more circuits and between 100 and 150 amps.
When should you add a subpanel?
When all the breaker slots in the main service panel are full and cannot accept any more circuits, a subpanel can be an ideal way to add additional circuits. By running a single 60-amp breaker to a subpanel, for example, you can then divide those 60-amps into several smaller circuits.
How much load can I put on a 100 amp panel?
