Components

• The main breaker: is a large double pole circuit breaker that limits the amount of electricity coming 
   in from outside to protect the circuits it feeds. It also identifies your breaker panel’s amperage capacity.
• Circuit breakers: are stacked in the panel and have an ON/OFF switch that controls the flow of power.
•  Bus bars: receive power from the two thick black wires that bring power in from the electrical meter. 
  The bus bars in turn carry power through the circuit breakers to the circuits.
•  Neutral bus:  bars connect to the main circuit’s neutral wire. The neutral bar provides the contact point for 
  the white wires that return electricity back to the breaker panel after flowing through the black wires to 
  power a device. Your home’s main grounding wire also connects to the neutral bar.
• Grounding bus bars:  unite all the grounding wires from the breaker panel’s various circuits and connect 
  them to the ground bar. It is also connected to a grounding conductor that leads underground, the metal 
  enclosure and, if it’s the main service panel, to the neutral bar; the ground bar is not connected to the 
  neutral bar at sub-panels

Types Of Main Panels

There are few different types of breaker panels that you might need upgraded.  Each of which meets a certain code requirement or application, depending on your area. Shocky Electric can check to determine which type of panel meets your local compliance requirements.
• Main breaker panels: Which has a built-in main breaker which can be used to shut off all power to your residence. A main breaker is a large double-pole circuit breaker that limits the amount of electricity coming in from outside to protect the circuits it feeds. It also identifies your breaker panel’s amperage capacity.

• Main lug panels:  Do not have a main breaker. Instead the line wires run to lugs. This type of breaker panel requires a separate disconnect. The main breaker, which would function as the disconnect, may be located at the meter, or if the main lug panel is used as a sub-panel, it may be connected to the breaker at the main panel. In the event of a fire, the separate disconnect at a meter can be helpful to fire authorities, who don’t have to enter the building to cut power.
