cord

The _____ of any system is the ratio of the maximum demand of a system, or part of a system, to the total connected load of a system.

demand factor

Systems of illumination utilizing fluorescent lamps, high-intensity discharge (HID) lamps, or neon tubing are all types of _____ lighting.

electric-discharge

Surrounded by a case, housing, fence, or wall(s) that prevents persons from accidentally contacting energized parts is called "_____."

enclosed

The installed conductive path(s) that is part of a ground-fault current path and connects normally noncurrent-carrying metal parts of equipment together and to the system grounded conductor or to the grounding electrode conductor, or both, is known as a(an) "_____ conductor."

equipment grounding
