I had a post last month about 180 amp heat strips in a plant we work in. I went yesterday to talk more about the job with them. They potentially have five of these setups which would be 900 amps. They asked me if there was enough capacity with the existing service to handle this.
It is a 80 year old thread plant. I am trying figure out a way to determine their capacity.
Could I look at their power usage over the last year and compare that to their current service size and capacity to determine what they are using or is this the wrong approach. Do I need to physically monitor power for different panels and do a load calculation? If so, what is the best equipment for this?
I know some of of you guys do this sort of thing. Your help is appreciated.
