having some experience in this field that doesn't look like an ATS (automatic transfer switch) or a switchgear room. looks like the dragged work lights down with them. these look like High voltage transmission lines but I'm not convinced its for what they say it is. to me it looks like either one of the emergency power lines failed and generated and arc (which can cause damage like that due to the heat generated by the arc). this definitely looks like something let the smoke out though. I've seen a lot of electrical damage and this matches what ive seen in the past. I've been saying it on the discord. places like this have required quarterly and yearly testing on all building essential equipment. they are required to simulate power shutdowns and verify that all the ATS work properly. can someone get info on how they provide emergency power? I am used to buildings having on board diesel generators that feed to the ATS and the building fire systems (fire pumps and air compressors for dry systems).
hope it helps out anon.
if needed I can bake next bread anon seems sleepy
