Abstract
A modular wiring system carries different types or classes of wiring in a single cable. The modular wiring system includes two conduits, one inside the other. The outer conduit is a Class I conduit and the inner conduit is a Class II conduit. The Class II wiring is carried in the inner conduit and the Class I wiring is carried between the inner conduit and the outer conduit. The outer conduit may be any type of material that is approved for Class I. The inner conduit meets the same voltage rating as the outer conduit. The inner conduit may include a non-conductive outer surface and an inner metallic sheath. The inner metallic sheath is grounded and provides separation between the Class I and Class II conductors.
