What proximity range must GFCI protection be located from the attachment plug for portable electric signs installed in wet locations?

For portable electric signs installed in wet locations, GFCI (Ground Fault Circuit Interrupter) protection must be located within 12 inches of the attachment plug. This requirement is in place to ensure the safety of users by minimizing the risk of electric shock in wet environments. Proximity is essential because it allows for immediate interruption of the circuit in the event of a ground fault, which is particularly critical in areas where moisture can increase the risk of electrical hazards.

By positioning the GFCI within this range, it ensures that the protection is accessible and operational as soon as the device is plugged in, enhancing safety for both temporary installations and frequent use in potentially hazardous conditions.
