Grounding lighting fixtures. Threre are specific requirements for grounding lighting fixtures. How must they be grounded and with what size conductors?

The following problems refer to grounding requirements. 1. What is the minimum size copper grounding electrode conductor for a service with three sets of parallel 350 kcmil conductors (three conductors per phase)?

What type of terminal seal is shown here? O Matte 68659 Cable Wire Interface

Airframe Electrical System Question: By what means should aircraft electrical circuits/wires be protected from excessive current? (Source: FAA AC 43.13-1B/2B)

Please answer in typing format solution

Most residential general lighting circuits are wired with 14-AWG copper conductors and are protected by 15-amp circuit breakers. However, there are many electricians who install 12-AWG copper conductors and protect them with 20-amp circuit breakers. How will you know which conductor size and which circuit breaker size will be used for the general lighting branch circuits in the house you are wiring?

Find the maximum distance between outlets when using #10 Cu THWN copper wire at 240V on a 20A single phase load w/o exceeding a 3 percent voltage drop.     What is considered the maximum. permissible drop for feeders and branch circuits per the NEC recommendation?

8. You're installing type AC cable. The armor coating of type AC cable is allowed for use as an equipmentgrounding conductor (EGC) because of itsA. liquid-tight fittings listed for EGC purposes.B. interlocking ribs that form a complete circuit.C. internal bare bonding strip.D. internal bare aluminum bonding conductor.
