Answers Graded A+
What is the purpose of the electrical panel in a home?
✔✔The electrical panel serves as the central hub for distributing electricity throughout the house,
managing circuit breakers, and protecting the system from overloads.
How can you tell if a circuit is overloaded?
✔✔An overloaded circuit may cause the circuit breaker to trip, flickering lights, or a burning
smell from outlets or devices, indicating that it can't handle the current demand.
What is the importance of using the correct wire gauge for different circuits?
✔✔Using the correct wire gauge ensures that the wires can safely carry the electrical load
without overheating, which helps prevent fires and maintains system efficiency.
Why are some outlets equipped with a reset button?
✔✔Outlets with a reset button are GFCI outlets designed to prevent electrical shock by cutting
off power when they detect an imbalance in electrical current.

, What safety equipment should always be used when performing electrical work?
✔✔Safety goggles, gloves, and a voltage tester should always be used to protect against injury
and ensure that circuits are not live before starting work.
What can happen if you connect a light fixture without a ground wire?
✔✔Connecting a light fixture without a ground wire increases the risk of electric shock and
makes the fixture more susceptible to electrical faults.
How does the layout of outlets in a room affect convenience?
✔✔A well-planned layout of outlets allows for easy access to power for devices, reducing the
need for extension cords and promoting a cleaner living space.
What should you do if an outlet is hot to the touch?
✔✔If an outlet feels hot, it should be immediately unplugged, and a qualified electrician should
be called to inspect it for potential wiring issues or overloads.
