Question

Please complete both, very confused

14. A device that establishes an electrical connection to the earth is a a grounding conductor C. grounding electrode b. equipment grounding conductor d.grounding electrode conductor 15. The size of an equipment grounding conductor is based on the size of in circuit. a. overcurrent protection device C. conduit b. one phase d. neutral

Answer 1

Answer 14 ) option (a) is correct

Grounding conductor- grounding conductor is  used to connect electric equipment or the grounded circuit of an electric wiring system to a grounding electrode or electrodes.

Grounding Electrodes- A conductor buried in the ground, used to maintain conductors connected to it at ground potential and dissipate current conducted to it into the earth.

Equipment Grounding Conductor- The conductor used to connect the non-current-carrying metal parts of equipment, raceways and other enclosures to the system grounded conductor, grounding electrode conductor, or both.

Grounding Electrode conductor-The conductor used to connect the grounding electrode(s) to the equipment grounding conductor, to the grounded conductor, or to both, at the service, at each building or structure where supplied by a feeder(s) or branch circuit(s).

Answer 15)option (a) is correct

The size of the equipment grounding conductor is based upon the rating or setting of automatic over current protective device in the circuit ahead of the electrical appliance or equipment.

Neutral is used by current for return path.

Phase is the main path of current supplied to equipment.
