- What is a circuit breaker?
Show answer
A switch that automatically stops electrical current if too much current flows through a circuit.- What happens when a circuit breaker trips?
Show answer
It switches off to stop the flow of electricity and prevent overheating and fire.- What should you do if a circuit breaker repeatedly trips?
Show answer
Call a licensed electrician to diagnose and fix the underlying problem.- What does GFCI stand for?
Show answer
Ground Fault Circuit Interrupter.- Where are GFCI outlets commonly required in homes?
Show answer
In bathrooms, kitchens, garages, basements, and near outdoor areas.- What does a GFCI outlet do?
Show answer
It detects imbalances in electrical current and cuts off power in milliseconds to prevent electrocution.- How quickly does a GFCI outlet cut off power?
Show answer
Within milliseconds, typically less than 5 milliseconds.- What is grounding in an electrical system?
Show answer
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?
Show answer
An additional ground wire for added safety.- What is the purpose of the ground pin on a plug?
Show answer
To provide a direct path for electricity to the ground, preventing electrocution if a short circuit occurs.- Can water and electricity mix safely?
Show answer
No, water is a conductor and creates serious electrocution hazard.- Why should electrical appliances be kept away from sinks and tubs?
Show answer
Water conducts electricity and can cause serious injury or death.- What should you never do when using electrical tools near water?
Show answer
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?
Show answer
No, only GFCI-protected outlets are safe for bathroom use.- What is an overloaded circuit?
Show answer
A circuit carrying more electrical current than it is designed to safely handle.
