E57:
Another honest man surfaces, OK I'll still say you presented the point(s) eloquently.
As to the 'handbook', I have to agree with you 100%, it's well worth the cost also. I tell that to my students.
Over the years, I (as an EC) have come upon many service installs that used the famous 'six switch rule' on the original, and the owners got the kick in the pants during renovation/remodel projects. Most of the time, economics play a role in the "no main" services, but the piper gets his due sooner or later. I came on one this week..
A 200/3 phase 'main' for a diner, and 4-60 amp 'mains' for the 4 apts. THe service conductors (250 RHW) are litterly 'baked' from overload, along with the 200/3 fused disc. It's time for an upgrade. Lack of a 'main' allowed overloading over the years, and prolonged a dangerous condition. Lack of doing load calcs, as new equipment was added over the years is a major contributor,
The old 'nothing tripped/blew' theory strikes again.
