On electrical drawings, a circle with the letters 'GFI' indicates what type of device?
Correct Answer
B) Ground fault interrupter outlet
GFI stands for Ground Fault Interrupter, which is a safety device required in wet locations like bathrooms and kitchens. The circle symbol indicates an electrical outlet with GFI protection.
Why This Is the Correct Answer
GFI stands for Ground Fault Interrupter, which is a critical safety device that protects against electrical shock by detecting ground faults and quickly shutting off power. On electrical drawings, the circle symbol with 'GFI' specifically indicates an electrical outlet equipped with ground fault protection. These devices are required by the National Electrical Code in wet locations such as bathrooms, kitchens, garages, and outdoor areas where the risk of electrical shock is higher due to moisture.
Why the Other Options Are Wrong
Option C: General facilities interface
Gas flow indicator would be found on mechanical or plumbing drawings, not electrical drawings. Additionally, gas-related symbols would use different abbreviations and would be part of the HVAC or plumbing symbol set, not electrical symbols.
Option D: Gas flow indicator
Generator fuel injection relates to mechanical engine components and would appear on generator equipment drawings or mechanical plans, not on electrical drawings showing outlet locations and electrical devices.
Memory Technique
Remember 'GFI = Ground Fault Interrupter' by thinking 'Get Free Insurance' - it's your electrical safety insurance against shock in wet areas.
