Has anyone ever installed surge suppresion on an entire building? The building in question is a movie theater. 480v 1200a service. Also would you buy a single lightning strike frying every single pole light ballast in an entire parking lot, as well as some equipment inside?
well if can run down a tree jump on a telephone wire & burn it off the wall(saw this happen twice). you may also find the wire missing to the poles.as for surge suppresion. ive seen some out there. ERWIN
TVSS is made by all the leading manufacturers as well as many after market people. Check out Power Quality's website.
As for your ballasts, sure, seen that a bunch. fuse each one at the bottom of the pole base at just above the normal draw takes care of a lot of the problem, you may lose a fuse occasionally, but rarely anything else. Made by AB Chance, Cutler hammer, and Bussman, I think Bussman makes the best ones.
