I had a question asked of me the other day, and sadly I answered it incorrectly “I think”
The question "what is the minimum size panel (65, 100, 150, 200 AMP) permitted in new construction?"
Since this question was asked, I though it would be simple to find a "code" source. I have looked and yes I understand that a load calculation has to be performed to asses the proper amperage.
What I am looking for is a code or other quotable source that states something like "if the calculations are below X, the minimum current standard panel is X"
Example the house has gas appliances and is a two bedroom on slab, the requirement is for 65 amp, however the minimum meter and panel requirement for new construction is 100 amp.
I almost fell asleep reading the NEC code and could not find this (not that I could not have missed it, imagine that)
I called the local county inspector and got referred to a state level code enforcement officer that has yet to return my calls.
I have looked at "HUD", formally they would not comment since they are regional now that is out of their jurisdiction to comment.???
I called the local utilities and was referred to a project manager that has yet returned the call.
A local supply house commented that they thought 100 amp was the minimum new service but could not provide any supporting documentation (they did look for it and could not find it either)
Any help would be appreciated, this has become a mission as opposed to just a question.
