The insulating boots are PPE frequently used by electricians as an auxiliary protection mean against electrocutions, in all LV, MV and HV electrical installations. The insulating boots have the role of a barrier against passing the electrical current between the live conductor and earth, through the human body. Also the boots constitute a protective mean against electrocutions as a result of touching with the legs of two different potential points, the human body being subjected at the difference between the two potentials (pace voltage).
The insulating boots are made of polymers or elastomers and have beside the electrical insulator properties also other protective characteristics against substances or media that can affect the human body:
A: acids resistance
H: oil resistance
Z: ozone resistance
C: low temperatures resistance (-40°C)
The insulating boots are protective means that require periodical dielectric testing in order to check if there are maintained their insulating properties. The test voltage is established by specific standards and the tests must be made in special conditions, in specially authorized laboratories by RENAR.

There is a class of insulating boots for works in LV electrical installations (class 0) and 2 classes for works in MV electrical installations (classes 1 and 2).
