Grounding and Bonding Level 1 Lesson 6: Grounding Electrode Conductor ...Bonding and grounding remove stray currents and static electricity, which are potential ignition sources when a flammable atmosphere is present. •Bondingis the equalizing of electric potential between two objects. It is achieved by joining metallic parts to form a path that ensures the safe conduction of any electrical current.

There are three types of liquidtight flexible nonmetallic conduit: LFNC-A, LFNC-B, and LFNC- C. True. A typical LFMC fitting contains five components: gland nut, sealing ring, ground cone, connector body, and locknut. True. A connector body has a preinstalled insulator. True. Gland nuts are often the "landing zone" for fluids.Lesson 302 - Introduction to Grounding and Bonding Objective 302.4 Worksheet. A 120-volt load is operating when you open the neutral in a j-box.

A connection to earth or some conducting body that serves in place of the earth, and can be intentional or accidental. Impedance. The resistance of a circuit (cable, passive devices are examples) to alternating current. Although it is measured in ohms, it can't be measured with the ohm portion of a volt-ohm meter. Bonding. oreo mudslide strain In a separately derived system, the equipment bonding jumper. connects the system housing to the neutral bus bar. AC systems over 1000V that supply mobile or portable equipment. are required to be grounded. The size of the equipment grounding conductor (EGC) is determined by the size of the overcurrent device.
