Hi guys,
I understand what you are saying and partically agree. Engineers do need to be as percise as possible as they are one of the prime targets for insurance companies in regards to law suits. And, whenever an electrican or contractor performs a "Design / Build" installation, he is now infact the engineer and a potentical target.
Knowing that we all want to do the best job possible and at one point we are only as good as our tools permit us, Volts becomes another tool option. Except, if doing Design / Build projects, it usually pays for itself in the first job.
Also and very important, voltage drop can very much be a safety issue!!!
