110.26(D):
"In electrical equipment rooms, the illumination shall not be controlled by automatic means only"
What does "automatic" mean?
Does everyone agree a motion sensor is automatic?
Would a programmable lighting control panel be considered "automatic only"? It has a low voltage wall switch that signals the panel to turn the light on or off. The panel would also be programmable to turn lights off at a set time, but the switch could turn them back on (last command wins).
