The network restricts the step-and-touch potential in areas accessible to personnel to levels below the lethal threshold even under lightning discharge and power fault conditions.

Other changes include the following: 

Green wire grounds must be run with power conductors and connected to equipment frames and housings Any external HVAC elements exposed to direct lightning strokes must have air terminals mounted thereon and be interconnected with roof and down conductors

Context Considerations

Any other external HVAC equipment located within 2 m of roof and down conductors should be interconnected with the nearest down conductor. TPDs installed on power and control cables interfacing with HVAC elements must be grounded to the enclosure of the protected equipment with minimum length conductors.
