What type of protection must all electrical equipment for fountains have?

In the context of electrical equipment for fountains, GFCI (Ground Fault Circuit Interrupter) protection is essential to ensure safety. This type of protection is specifically designed to immediately cut off electrical power in the event of a ground fault, which can occur when there is an unexpected path for electricity to flow, such as through water. Given that fountains often involve water, this creates an inherent risk of electrical shock, making GFCI protection crucial to prevent serious accidents.

According to the National Electrical Code, GFCI protection is mandated for all outdoor receptacles and equipment that could potentially be exposed to water. The ability of GFCI devices to detect imbalances in current flow means they can effectively provide protection against electrical shock, which is critical in wet environments like those created by fountains.

This requirement emphasizes the importance of ensuring safety for both users and maintenance personnel who might be working around or interacting with electrical components in such settings.
