We have received a notice that GFP testing on our SES is due (from the Co. that installed it). While we are pro-active in our preventative maintenance on this building, the Property manager is concerned about cost and down time. Since our insurance carrier has not required this test yet, is it necessary? Is this testing best done by the power company or a private contactor? Since the very thought of a deliberate power-down of the building has everyone wringing their hands in anguish, can someone give me an idea of the time frame for this test?
