Q: What is the primary function of a Ground Fault Circuit Interrupter (GFCI)?

To protect against electric shock by quickly interrupting the circuit when a ground fault is detected. — GFCI's are designed to protect against electrocution by detecting and quickly interrupting ground faults.

Q: Which of the following should you do FIRST if someone is being electrocuted?

Turn off the source of electricity if it's safe to do so. — Safety comes first. Turn off the power if possible before attempting rescue to prevent further harm to yourself.

Q: What is the safe distance to maintain from overhead power lines?

At least 10 feet (3 meters). — A safe distance prevents accidental contact or arcing from high-voltage lines. Regulations vary, but 10 feet is a good rule.

Q: Why is it important to use the correct size fuse or circuit breaker?

To prevent overloading the circuit and causing a fire. — Overcurrent protection is essential to prevent damage to wiring and appliances and to prevent fires.

Q: What is the purpose of electrical grounding?

To provide a low-resistance path for fault current to return to the source, activating overcurrent protection. — Grounding creates a safe path for fault current, tripping circuit breakers or blowing fuses in case of a fault.
