Substantiation

General

NEC 2014 contains 317 sentences containing nominal. It contains 2744 sentences containing volts, voltage, or V. It is clear that the use of (or absence) nominal modifying voltage references follows no particular pattern. Having nominal appear and not appear with voltage references when nominal is the intention adds confusion and is in conflict with NEC_StyleManual_2011.pdf:

"3.3.5 Parallel Construction. Parallel construction means stating similar requirements in similar ways for greater consistency. This helps makes the NEC clear for users. Lack of consistency often creates confusion, causing users to ask: Does this difference in wording represent a different requirement? Or is it simply two different ways of trying to say the same thing?"

I suspect that nearly all, if not all, voltages are nominal voltages. It would be simpler to indicate that all voltages are nominal unless denoted actual and remove nominal from the text.

Specific

This submission deletes the term nominal in all its forms --- initial caps or not, preceded and/or followed by commas.

There are roughly 20 sections that use nominal either to support the default use of nominal with voltage or its use with measurements other than voltage. These should be retained and are listed in "NEC_non_V_nominal" and "NEC_save_nominal" submissions.

Coordination

This needs to be coordinated with submissions whose titles contain

Nominal Voltage
