Flat multiconductor cable for undercarpet wiring system
First Claim
1. An electrical cable for use in an undercarpet wiring system wherein said cable is likely to be exposed to an alkaline environment, said cable comprising:
- a plurality of elongate electrical conductors extending generally parallel to each other in side by side relation, said conductors including live, ground and neutral conductors,a layer of insulation individually surrounding each of said live and said neutral conductors,a casing of insulation surrounding said conductors and being in adhered relation to said respective layers of insulation surrounding said live and said neutral conductors, said casing substantially surrounding said ground conductor and being in contact therewith, said casing of insulation being substantially free from attack in an alkaline environment.

Abstract
The flat multiconductor cable contains live, neutral and ground conductors lying generally parallel to each other and in side by side, single-plane relation. The live and neutral conductors are sealably surrounded by a relatively hard, polyetherimide material that is substantially free from attack from calcium hydroxide. An outer jacket or casing of polyvinylchloride (PVC) sealably surrounds the polyetherimide layers and contacts the ground conductor. The PVC is substantially free from attack in an alkaline environment. As such, the cable construction provides an enhanced resistance to puncture, particularly in alkaline environments which may be encountered in undercarpet wiring system applications.

- 12. An electrical cable for use in an undercarpet wiring system comprising a live conductor, a ground conductor and a neutral conductor extending in generally parallel, side by side, spaced relation, a layer of relatively hard insulation individually adheringly surrounding each of said live and neutral conductors, and a casing of insulation surrounding said conductors, said casing being in adhered relation to said respective layers of insulation and substantially surrounding and contacting said ground conductor and arranged thereon such that removal of a portion of said casing will expose said ground conductor for making electrical connection thereto.
