I have a simple question I cant figure out. Why do or why is a service upgrade (say 100 amp to 200amp) considered or called a heavy up? Whats heavy about it? Should it not be called a standard up? How did that name come about?
I only ask because I hate to title something when I really dont know what it means, and I hate to just go with the flow because thats what everyone calls it.
