What is a circuit breaker?
A switch that automatically stops electrical current if too much current flows through a circuit.
What happens when a circuit breaker trips?
It switches off to stop the flow of electricity and prevent overheating and fire.
What should you do if a circuit breaker repeatedly trips?
Call a licensed electrician to diagnose and fix the underlying problem.
What does GFCI stand for?
Ground Fault Circuit Interrupter.
Where are GFCI outlets commonly required in homes?
In bathrooms, kitchens, garages, basements, and near outdoor areas.
What does a GFCI outlet do?
It detects imbalances in electrical current and cuts off power in milliseconds to prevent electrocution.
How quickly does a GFCI outlet cut off power?
Within milliseconds, typically less than 5 milliseconds.
What is grounding in an electrical system?
A safety path that directs excess electricity safely into the earth through a ground wire.
What does a three-prong plug provide that a two-prong plug does not?
An additional ground wire for added safety.
What is the purpose of the ground pin on a plug?
To provide a direct path for electricity to the ground, preventing electrocution if a short circuit occurs.
Can water and electricity mix safely?
No, water is a conductor and creates serious electrocution hazard.
Why should electrical appliances be kept away from sinks and tubs?
Water conducts electricity and can cause serious injury or death.
What should you never do when using electrical tools near water?
Never touch them with wet hands or stand in water while using them.
Is a regular electrical outlet ever safe to use in a bathroom?
No, only GFCI-protected outlets are safe for bathroom use.
What is an overloaded circuit?
A circuit carrying more electrical current than it is designed to safely handle.
