We can say it was an overloaded feeder but we do not have to say the overload was caused by Ted Kennedy's beverage cooler.
ROTFL
Are you trying to say it pulls 50KVA?
I know what youre saying but dont see it as a red/blue or four horsemen item.
But seriously, a micro example would be putting a 30Ksq' office space on a 50A feeder because it works most of the time. And knowing full and well it wont work on monday mornings in the summer.
