Florida Home Inspector Practice Test 2026 – Comprehensive Exam Prep

The correct amperage for copper wires sized 14 is 15 Amperes. This is in alignment with the National Electrical Code (NEC), which provides guidelines for the safe amperage ratings of different wire sizes. Copper wire size 14 is typically rated for a maximum of 15 amps in residential wiring for general-purpose circuits.

Understanding why this rating is crucial for safety and performance is essential for home inspectors. When determining the capacity of electrical circuits in a home, adherence to these amperage ratings ensures that wiring does not overheat, leading to potential fire hazards. Additionally, if a circuit is loaded beyond its specified amperage, it can trip breakers or cause electrical component failure.

In the context of electrical systems, this means that when installing or inspecting circuits utilizing 14-gauge copper wire, the recommendation is to limit the load to no more than 15 Amperes to maintain safety and compliance with applicable electrical codes.
