ICC Residential Electrical Inspectors Practice Exam

When considering the maximum load for a flexible cord, which wire gauge is being referred to here?

1. 14 AWG

2. 16 AWG

3. 18 AWG

4. 20 AWG

The correct answer is: 16 AWG

In the context of flexible cords, the maximum load a particular wire gauge can handle is crucial for determining safe usage in various applications. The wire gauge referred to in this question is 16 AWG. This gauge is commonly utilized for a range of general-purpose power applications and is recognized for its balance between conductivity and flexibility. 16 AWG wire is capable of carrying a reasonable amount of current—typically up to about 10 amps, depending on the insulation type and temperature rating. This makes it suitable for many household appliances, tools, and lighting applications. Using a flexible cord at its maximum load capacity ensures that it can handle the electrical demands without risk of overheating or damaging the cord itself. In contrast, the other gauge options—14 AWG, 18 AWG, and 20 AWG—have different current-carrying capacities, with 14 AWG being slightly thicker and able to carry more current, while 18 AWG and 20 AWG are thinner and suitable for lower current applications. Therefore, 16 AWG finds its place as a practical choice for flexible cords in typical residential uses, making it the appropriate answer in the context of maximum load considerations.
