What is the main purpose of a clearance order in electrical work?

The main purpose of a clearance order in electrical work is to ensure complete isolation of equipment. This procedure is crucial for maintaining safety during maintenance or repair activities. When a clearance order is issued, it signifies that all necessary measures have been taken to disconnect electrical equipment from its power source, thereby preventing any unintentional re-energization while personnel are working on or near the equipment.

Complete isolation is vital for protecting workers from electrical hazards, as accidental contact with live power lines or energized components can lead to serious injuries or fatalities. The clearance order serves as a formal acknowledgment that the equipment has been tested and confirmed to be de-energized, ensuring that appropriate safety protocols have been followed.

The other options touch on aspects of maintenance and repair processes but do not address the primary objective of a clearance order, which is centered around safety through isolation. For instance, allowing maintenance on energized systems can create dangerous conditions, and documenting equipment performance or scheduling repairs are important tasks, but they do not directly relate to the immediate safety measures enforced through a clearance order.
