Article 382 Nonmetallic Extensions

I. General

This is a conductor arrangement with two insulated conductors in a nonmetallic jacket or thermoplastic cover.

II. Installation

Only from an existing 15- or 20-A outlet on a branch circuit. It must be run exposed and dry. For surface extensions the buildings must only be occupied for residential or office use and with height restrictions of three floors above grade.

This type of extension cannot be used in unfinished areas, where there are corrosive vapors, through a floor or partition; and where the voltage between conductors is greater than 150 V for surface work and 300 V for aerial cable.
