🔍 Key Concepts

• Ground Fault Interrupter (GFI / GFCI) purpose • Difference between overcurrent protection and shock protection • How electricity behaves when it finds an unintended path to ground

💭 Think About

• Think about what dangerous situation this special type of outlet is specifically designed to detect and react to very quickly. • Which choice describes an electrical fault involving current leaking to ground, rather than just too much current overall? • Ask yourself: where are these outlets usually required on a boat or in a house, and what hazard is common in those locations?

✅ Before You Answer

• Identify which option involves ground fault / leakage to ground, not just extra current or physical blockage. • Eliminate any choices that describe mechanical childproofing rather than electrical sensing. • Eliminate any options that talk about increasing current capacity or cosmetic features like plating, since that is not the function of a GFI.
