When I have a lightning protection system installed on a building roof top , what is the best way to bond the electrical equipment on the roof? Is it ok to directly bond it to the down counductor of the LPS? or different measures should be taken?
Lets say I have multiple air-condition units on the roof, how can I safely bond them to the lightning protection system. With bonding here I mean bonding the metalic body of the units.
Lets say if I bond the body directly to the down conductor, in case of a lightning strike will current pass through the unit and destroy the electronics inside it or will it only follow to the down conductor and to the ground?
