What is the circuit in the given diagram called?

You are an electrician working in an industrial plant. The company is constructing a maintenance shop located 225 feet from the main plant electrical system. You are to install a 400-ampere three-phase wire system in the new maintenance shop. The service is supplied by the existing plant service. The voltage is 480 volts and the voltage drop is to be kept at 3% or below at full load. The conductors are to be aluminum. What size conductors should be installed for the new service? Express your answer to the nearest standard wire size. (Note: Determine the wire size by calculating length, resistance, and voltage drop as opposed to using the National Electrical Code.)

This is a general question: How do smaller electrical engineering labs relate to building a relatively larger system?

Evaluate the relationship between lighting design and electrical circuit design for a non-domestic installation. Describe how electrical circuits are used in a lighting wiring system. Describe grounding system in a lighting circuit and lighting switching system and control.  Demonstrate your work with schematics and layouts. Evaluate the similarity and difference between small power and lighting wiring system.
