75 amps to run two fans??
There are small houses that run on a hundred amps.
Those have to be some very serious electric motors to demand that kind of juice. Even at initial startup they require 75 amps to get turning?
We operate a 20,000 watt HMI or Zenon par motion picture lamp that usually requires 32 - 50 amps depending on the lamp.
There should be a lable somewhere on the fan motor listing the max amperage consumed.
Are you sure it is not 18.5 amps per fan motor (which still sounds high) but more reasonable. Even with the high rpm's those fans turn, 75 amps??
Maybe I am just being naive but that really does sound like way too much muscle required for a couple of cooling fans.
