Abstract: The present invention is a toneable conduit that can transmit a signal and that can therefore be readily detected by toning equipment. In addition, the conduit of the invention can be readily coupled with other conduit to provide extended lengths of conduit. The toneable conduit includes an elongate polymeric tube having a wall with an interior surface, an exterior surface, and a predetermined wall thickness. A channel preferably extends longitudinally within the wall of the elongate polymeric tube and a stabilizing rib extends longitudinally along the interior surface of the wall of the elongate polymeric tube and is located radially inward from the channel. A continuous wire is coincident with the channel in the elongate polymeric tube and is preferably coated with a coating composition that prevents the wire from adhering to the polymer melt used to form the elongate polymeric tube.

Abstract: The aim of the invention is to protect an electromagnet switching device when a load is switched to a supply voltage. A current that flows through the load contact is monitored. The electric circuit is interrupted when the current exceeds a threshold value that is below the current carrying capacity of the load contact. The electric circuit is automatically closed again after the current which flows through the load contact has decreased.
