The Main Circuit Breaker
This is the switch that goes on and off to control the flow of current. So if there is an overload due to a short circuit or because too many appliances are running simultaneously, the corresponding circuit breaker automatically trips to shut off the flow of current.Standard breakers can be further subdivided into the following two categories:
Arc Fault Circuit Interrupters
These are special purpose circuit breakers designed for additional safety against electric fires and electrocution. Sub-Panels – sub-panels are small breaker boxes designed to handle more circuits when you don’t have the space to accommodate new circuits.
Bus Bars
The two rows in the main circuit breaker panel connect to hot bus bars. This is where the current flows from the main breaker to the branching circuits and reaches the outlet.
GFCI stands for Ground Fault Circuit Interrupter. Any device with a GFCI component protects you from receiving electrical shocks from faults in the electrical devices we use in our home. GFCI protected devices and outlets should be used anywhere there is the possibility of moisture accumulation, like kitchens and bathrooms.
