On the platform, they installed two, 3-phase 480V, disconnect switches directly across from the handrail at exactly 36" from the front of the switch. Assuming the handrail represents 'grounded parts' (condition 2) the requirement is 3'-6" of minimum clearance.
I don't believe raising the switches above the handrail would work since they'd still fall within the 6.5 feet 'Height of Working Space'.
Can the handrail be 'effectively insulated' and call it condition 1? If so, what kind of insulation would be acceptable?
