What is a 3 conductor wire?
Conductor is the term used for wires that are in a cable. For example a 3 conductor romex cable has 3 separate wires inside the cable. The wires insulation are typically color coded for the sole purpose of identifying one wire from another.
What is direct burial cable?
Direct-burial cable is a special type of electrical wiring, or cable, that is designed to be buried in a trench underground . The individual electrical conducting wires inside the cable are encased in a solid thermoplastic sheath that seals out moisture and protects the conducting wires within. Oct 27 2019
What is a 3 wire control circuit?
Three-Wire Control. The most basic three wire control circuit is the start/stop circuit. The basic operation of the stop/start circuit is to provide a means of remotely controlling a motor operated load from a panel that only contains the low voltage control circuitry.
