727.1 Scope. This article covers the use, installation, and construction specifications of instrumentation tray cable for application to instrumentation and control circuits operating at 150 volts or less and 5 amperes or less.
727.2 Definition.
Type ITC Instrumentation Tray Cable. A factory assem- bly of two or more insulated conductors, with or without a grounding conductor(s), enclosed in a nonmetallic sheath.
727.3 Other Articles. In addition to the provisions of this article, installation of Type ITC cable shall comply with other applicable articles of this Code.
121A Uses Permitted. Type ITC cable shall be permitted to be used as follows in industrial establishments where the conditions of maintenance and supervision ensure that only qualified persons service the installation:
(1) In cable trays.
(2) In raceways.
(3) In hazardous locations as permitted in 501.10,
502.10, 503.10, 504.20, 504.30, 504.80, and 505.15.
(4) Enclosed in a smooth metallic sheath, continuous corrugated metallic sheath, or interlocking tape armor ap-plied over the nonmetallic sheath in accordance with 727.6. The cable shall be supported and secured at intervals not exceeding
1.8 m (6 ft).
(5) Cable, without a metallic sheath or armor, that complies with the crush and impact requirements of Type MC cable and is identified for such use with the marking ITC-ER shall be permitted to be installed exposed. The cable shall be continuously supported and protected against physical damage using mechanical protection such as dedicated struts, angles, or channels. The cable shall be secured at intervals not exceeding 1.8 m (6 ft).
(6) As aerial cable on a messenger.
(7) Direct buried where identified for the use.
(8) Under raised floors in rooms containing industrial process control equipment and rack rooms where arranged to prevent damage to the cable.
(9) Under raised floors in information technology equipment rooms in accordance with
645.5(D)(5)(c).
727.5 Uses Not Permitted. Type ITC cable shall not be installed on circuits operating at more than 150 volts or more than 5 amperes.
Installation of Type ITC cable with other cables shall be subject to the stated provisions of the specific articles for the other cables. Where the governing articles do not contain stated provisions for installation with Type ITC cable, the installation of Type ITC cable with the other cables shall not be permitted.
Type ITC cable shall not be installed with power, lighting, Class 1 circuits that are not power limited, or non-power-limited circuits.
Exception No. 1: Where terminated within equipment or junction boxes and separations are maintained by insulating barriers or other means.
Exception No. 2: Where a metallic sheath or armor is applied over the nonmetallic sheath of the Type ITC cable.
727.6 Construction. The insulated conductors of Type ITC cable shall be in sizes 22 AWG through 12 AWG. The conductor material shall be copper or thermocouple alloy. Insulation on the conductors shall be rated for
300 volts. Shielding shall be permitted.
The cable shall be listed as being resistant to the spread of fire. The outer jacket shall be sunlight and moisture resistant.
