An electrically insulating Class 2 dielectric boot with an integral steel toe cap and vulcanized rubber sole for superior slip resistance. The class 2  Dielectric boot provides high voltage protection of up to 20kV over the complete boot for over 8 hours, and 35kV over the sole for 3 minutes. This high-voltage boot is suitable for use by electricians, utility engineers and live working up to 17kV

EN 50321-1:2018 is the new standard for insulating footwear for live working and was published earlier this year, it replaces EN 50321:1999 and is currently out for approval as an IEC standard which will make it a global standard, not just European.

The main changes in the 2018 revision are the introduction of new 4 classes (see below) for working up to 36 KV (the old standard only went up to Class 0 - 1 KV). Boots are now tested by filling with water instead of ball bearings to simulate water or perspiration potentiality wicking up the lining and creating a flash over. There is also now an electrical test after perforation of the sole by a nail, to ensure boots still give electrical protection after perforation. Even non-metallic perforation inserts can allow water to pass through them so will allow an electrical current to pass when the sole is punctured. The table below lists the classes and the test requirements:

Class RatingMaximum Working VoltageWithstand Test VoltageLeakage Current Test VoltageMaximum Leakage Current
Class 00500V5kV2.5kV3mA
Class 01kV10kV5kV5mA (8mA)
