What does 'externally operable' mean in relation to electrical equipment?

The term 'externally operable' refers specifically to the ability to operate electrical equipment without exposing the operator to live components. This characteristic is paramount for safety, as it helps to minimize the risk of electrical shock or injury while maintaining and using the equipment. Equipment designed to be externally operable allows users to perform necessary functions, such as turning it on or off, without having to reach inside or come into contact with any energized parts.

The other options pertain to different qualities of electrical equipment but do not accurately define 'externally operable.' For example, equipment being suitable for hazardous locations addresses safety in potentially explosive atmospheres, while accessibility from multiple entry points relates to operational efficiency but not to safety. Weatherproof equipment that can be used outdoors speaks to environmental resilience but does not encapsulate the safety aspect inherent to the definition of being 'externally operable.' Focusing on the critical safety aspect of operating equipment without contacting live parts solidifies the understanding of this term in electrical safety standards.
