What is a requirement for GFCI protection in wet location installations?

The requirement for GFCI (Ground Fault Circuit Interrupter) protection in wet locations is pivotal for ensuring safety and preventing electrical hazards. For installations in wet environments, the GFCI must be installed to effectively minimize the risk of electrical shock caused by ground faults.

The correct answer emphasizes that GFCI protection should be installed within a specific distance from the power source, which is critical. This requirement ensures that the GFCI can detect any ground faults immediately and disconnect the power in a timely manner, reducing the risk of electrocution or electrical fires that could arise in wet conditions. By placing the GFCI at the right distance, it is better positioned to monitor the circuits effectively.

Other options, while they may present considerations for electrical installations in general, do not align with safety protocols set for GFCI use in wet environments. For example, battery-operated devices may offer some protection but are not the primary requirement for GFCI installations. Similarly, the placement of cord lengths and the use of extension cords can introduce additional hazards or may not conform to code requirements. Hence, the focus remains on ensuring GFCI is properly positioned to protect against ground faults, which is crucial in areas prone to moisture.
