ii. Dry location--A location not normally subject to dampness or wetness. A location classified as

dry may be temporarily subject to dampness or wetness, as in the case of a building under

construction.

iii. Wet location--Installations underground or in concrete slabs or masonry in direct contact with

the earth, and locations subject to saturation with water or other liquids, such as vehicle-washing

areas, and locations exposed to weather and unprotected.

May--If a discretionary right, privilege, or power is abridged or if an obligation to abstain from

acting is imposed, the word "may" is used with a restrictive "no," "not," or "only." (E.g., no employer

may ...; an employer may not ...; only qualified persons may ...)

Medium voltage cable--Type MV medium voltage cable is a single or multiconductor solid

dielectric insulated cable rated 2000 volts or higher.

Metal-clad cable--Type MC cable is a factory assembly of one or more conductors, each

individually insulated and enclosed in a metallic sheath of interlocking tape, or a smooth or

corrugated tube.

Mineral-insulated metal-sheathed cable--Type MI mineral-insulated metal-sheathed cable is a

factory assembly of one or more conductors insulated with a highly compressed refractory mineral

insulation and enclosed in a liquidtight and gastight continuous copper sheath.

Mobile X-ray--X-ray equipment mounted on a permanent base with wheels and/or casters for

moving while completely assembled.

Nonmetallic-sheathed cable--Nonmetallic-sheathed cable is a factory assembly of two or more

insulated conductors having an outer sheath of moisture resistant, flame-retardant, nonmetallic

material. Nonmetallic sheathed cable is manufactured in the following types:

Type NM--The overall covering has a flame-retardant and moisture-resistant finish.

ii. Type NMC--The overall covering is flame-retardant, moisture-resistant, fungus-resistant, and

corrosion-resistant.

Oil (filled) cutout--(Over 600 volts, nominal.) A cutout in which all or part of the fuse support and

its fuse link or disconnecting blade are mounted in oil with complete immersion of the contacts and

the fusible portion of the conducting element (fuse link), so that arc interruption by severing of the

fuse link or by opening of the contacts will occur under oil.

Open wiring on insulators--Open wiring on insulators is an exposed wiring method using cleats,

knobs, tubes, and flexible tubing for the protection and support of single insulated conductors run

in or on buildings, and not concealed by the building structure.

Outlet--A point on the wiring system at which current is taken to supply utilization equipment.

Outline lighting--An arrangement of incandescent lamps or electric discharge tubing to outline or

call attention to certain features such as the shape of a building or the decoration of a window.
