I've read the definition and fpn for Nonlinear load in Art 100 and with reference to 310.15(B)(4)(c) when applying the neutral as a ccc, my question is what constitutes a linear load, what supply voltages does this normally apply to and is it practical to just calculate the above mentioned article due to existing demand factors?

The concepts of ?non-linear load? and ?demand factor? are completely unrelated to each other. A load is ?non-linear? if you apply a smooth sine wave curve for voltage, and do not get a similarly smooth sine wave curve for current. Examples of non-linear loads include fluorescent lights, arc welders, computers (i.e., their internal power supplies) and variable frequency drives. A load can be non-linear at any voltage level.
