The objective of this document is to provide basic recommendations, good work practices, and requirements for the safety of personnel in proximity to or engaged in the maintenance of electrical switchgear and provide detailed recommendations for specific types of switchgear.
This document applies to electrical switchgear above 1 000 V a.c. and 1 500 V d.c.
NOTE 1 At voltages above 145 kV, the design of equipment, system operations and maintenance requirements and practices may differ significantly from those operating at voltages up to this level. However, the principles formulated in this document, especially those related to the safety of personnel, are mostly applicable at the higher voltages.
NOTE 2 While the design, system operations, and maintenance requirements and practices for equipment operating above 145 kV may differ significantly from those operating at voltages below this level, the principles formulated in this document, especially those related to the safety of personnel, may be applicable at the lower voltages.
This document does not apply to live work.
This document does not apply to the maintenance of electrical switchgear that is —
(a) of sealed construction, intended only to be returned to the manufacturer for adjustment or repair;
(b) used in explosive atmospheres and in coal mines; or
(c) used in live (or live-line) electrical work techniques.
