What is the definition of a clearance order in electrical work?

A clearance order in electrical work refers specifically to the complete electrical isolation of equipment. This is crucial in ensuring that all sources of electrical energy are removed, safeguarding workers during maintenance or repair tasks. The process typically involves disconnecting the equipment from its power source and ensuring that it cannot be re-energized until the work is completed and the system is cleared for use again.

This full isolation is essential because it provides a safe working environment, not only by eliminating the risk of electrical shock, but also by allowing maintenance personnel to work with confidence that the equipment is completely off and secure. In contrast, other options such as temporary disconnection, partial disconnection of services, and regular maintenance checks do not provide the same level of safety and certainty as a clearance order, which emphasizes the importance of complete electrical isolation in protecting workers during electrical tasks.
