2 Mounting and Connection Molded Case Circuit Breakers vInsulation distance from the line side The insulation distance between the breaker and earthed metal parts and insulators shown in the table on the next page must be maintained to prevent arcing faults occurring due to conductive ionised gas. In addition, completely cover exposed conductors, to their roots at the breaker or to below the height protected by interpole barriers, on the line side of the breaker using insulation tube or tape, in order to provide positive ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ protection against short...
