Hi
I have seen electric technicians while racking out high tension circuit breakers, use a wire that has one end grounded and they use the other end to touch the bus bars on the breaker in case of a static charger, they carry out this procedure before they do any work on the CB in case they get shocked by a static charge, is it necessary to carry out such a procedure even tho the breaker is completely isolated ?
How can static charge be built in a case like that, where there is no friction ?
