Art 700 wiring

[Isaiah]

Construction has installed an Inverter to act as the source for an “emergency” lighting system. They’re saying the wiring has to be in a separate conduit, but I don’t believe this meets the criteria of art 700, ie there is no genset involved and I don’t believe human life is at risk.
Any thoughts?

I don't see language in 700.1 scope and 700.2 Emergency Systems that limits a 700 system to generators.
Its common in larger buildings to install inverters for E lighting instead of multiple bug eye lights. A army base and naval station I instructed classes at always used inverters for e lighting. The interter would of course be listed as a e-light source.
If the inverter or wiring fails then there would be a risk to human life, unless I am misunderstanding something

My opinion is, that you are incorrect. In fact, I believe that the wiring between, for example an emergency/exit light and a remote head outside the door is a "legally required emergency system" You inverter and the associated load wiring is a "legally required emergency system" and as such must be wired per article 700.

Agreed — thanks to Tom and Strathead
