An electrical panel is basically a service box that connects a main power line to a home, and distributes electrical currents to the various circuits within the home. Circuit breakers and fuses ensures there are no over-currents during the distribution of power to different circuits.

What is the difference between a breaker box and an electrical panel?
Electrical panels are metal boxes, that have a panel cover, and store circuit breakers. Circuit breakers are mechanical switches that automatically detect current overage. Circuit breakers do not have to be replaced when they are triggered by a current overage. Rather, the switch can just be reset.
How do I know which circuit breaker is controlling?
If your helper can’t readily identify a location that’s connected to a breaker, mark the area next to the breaker with a small dot. Come back to it after you have finished identifying the rest of the circuit breakers. You can then look at the plans and figure out what location goes with the breaker in question.
How does a home electrical panel work?
Power leaves the electrical panels on hot or energized wires, works through the device or outlet, and then the current comes back to the panel along neutral wires. Electrocution occurs when a person’s hands touch hot and neutral conductors, which causes the current to complete its circuit through the body.
Where are electrical panels used?
Electrical Panel is a compact place or center where all switchgear, busbar, feeders are housed. From an electrical panel we can easily control, measure, and operate electrical power and devices.
What is the use of panel board?
A panelboard is a component of an electrical distribution system which divides an electrical power feed into branch circuits, while providing a protective circuit breaker or fuse for each circuit, in a common enclosure. A panelboard services to protect branch circuits from overloads and short circuits.
How can I tell if I have 100 or 200 amp service?
Inspect the gauge of the main service wire, if you can see it. Six gauge copper wire can carry 60 amps, four gauge indicates 100 amps, 2 gauge carries 125 amps, 1 gauge corresponds to 150 amps and 2/0 gauge carries 200 amps. Generally speaking, the lower the gauge number, the larger the wire.
How do you reset a circuit breaker?
Reset the Breaker
To reset a breaker, move the switch all the way to its ‘off’ position, then back to ‘on’. You might hear a few beeps from smoke detectors and appliances when you turn the power back on, but that’s normal. You’re good to go!
