ABSTRACT:
In a wall structure comprising parallel sole and head members and vertical stud members a wiring channel of C cross-section is fastened to the structure and constitutes a raceway for electrical wiring. The open face of the channel is closed by the sheet applied to the corresponding face of the wall member to permit the use of ordinary unarmored cable therein. A bridging channel is used to convey the cable between two walls abutting at right angles to prevent sharp bends in the cable.
