I'm not. It's about owning up when I am.

Just curious. You posts have a similar feel - you know, like Shakespeare and Francis Bacon. Thought occurred to me maybe you worked together. I'm not thinking anything criminal here - I promise.

The 200A MCB protecting the switchback horizontal bus is a micrologic with LSIG - do any of these settings need to be adjusted due to the additional motor load - 15hp @ 21FLC?

I am removing this since its not relative to the original inquiry
I really don’t see how these can be done as the rules state. What if the utility reconductors the line, changing the X and R, or changing the transformer, changing the Z. Now every calculation inside the premise is off. It isn’t the utilities responsibility to let every contractor know about system changes. That could be the reason for the five year revisit, but has anyone been asked to do a five year analysis, just because it’s been five years?

Yes, I have several customers that have their AF studies updated on a 'timed' basis.

I also have clients that do a 5 yr update and I have clients who send me changes within the 5 yr window in which I will usually do an addendum to the report to capture that change along with labels.
