    Hi Shaun,

    MainPower has the following requirements for HV operating and earthing:

    11,000 V, Class 1

    22,000 V, Class 2

    33,000 V, Class 3

    66,000 V, Class 4

    The risk to workers is exposure to phase-to-earth voltage, not phase-to-phase voltage.

    Regarding the rating of Class 4 insulating gloves, Salisbury brand state a maximum use voltage (when worn with leather protectors) of 36 kV a.c. This is under to phase voltage value (38.1 kV) for a line voltage of 66 kV.

    However, as far as I am aware, there doesn’t appear to be an alternative option.

    Regards

    Stephen
