22、insulating sticks are used to operate high voltage (more than 1 kV) live equipment at distance, such as opening and closing switchgear, extracting and replacing fuses, etc. They are also used to carry out operations prior to dead working, as in the case of voltage verification, earthing and short-ci
23、rcuiting, etc. In all these cases the stick has two main functions, to reach the part of the installation that needs to be operated on and to protect the worker from risk of electrical injury, by providing the insulation level and maintaining the safety distance between the worker and the live or po
24、tentially live installation. According to the working and maintenance procedures adopted, additional protection can be added in order to attain the adequate safety level (see Annex A). The multipurpose insulating stick is used in accordance with EN 50110. This standard has been prepared in accordanc
