I was having a discussion with someone on a differant board and it was brought up that Aluminum wire could not be used to feed from service to panel. It was a not an electrician. Is this true and what is the reasoning behind it. Here in the state of Utah it is all that is used and don't see any problems with it when used correctly.
He also stated that for any home that is going to have central AC they had a 200 amp minimun on service requirments. Regardless of your load calculations.
I have been told various things by mis informed people as well. The last one was that #14 wire is no longer allowed in new construction. This same person was "helping" a friend with a 200 amp upgrade, they were at Home Depot buying a piece of 2" EMT for the overhead riser. (Our POCO requires IMC). I just smiled at them and said good morning.

Really??? Aren't window shakers considered fastened-in-place equipment and therefore have to be tallied on a service calculation (that is assuming they were planned for when the electrician installed the service).

Yes of course if the window unit were planned on you would have to consider it. Even after the fact it should be considerd.
The question still lies. If you do the math on a home in Knoxville and come up with only needing a 100 amp service or even a 125 but becuase you have electric range dryer and an AC unit you will be required to install a 200 amp service.
Also is aluminum wire ,SER, allowed or not from service to panel and if not what is the reasoning behind any of it .
Anyone from the city of Knoxville I mailed has yet to respond.
