Electric utility installations and equipment under the exclusive control of the utility donot have to conform to the National Electrical Code. However, they do have to conform to the . 2. Assume you are an electrical apprentice. The electrical foreman on the job tells youto connect some equipment grounding conductors to the ground bus that runs alongthe front bottom of a dead-front switchboard. The system is 480Y/277-volt solidlygrounded wye. The building is still under construction, and a number of other tradesare working in the building. The switchboard has already been energized, and it istotally enclosed except for two access covers near the front bottom where the groundbus runs. The ground bus already has the proper number of and size of lugs for theequipment grounding conductors. You ask permission to turn off the main power sothat you can work on connecting the equipment grounding conductors to the groundbus without having to worry about accidentally touching the phase buses…arrow_forward

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. Determine the wire size needed for the 400-ampere service in accordance with the National Electrical Code. Assume that the conductors have type THWH insulation. (Note: As a general rule, for each 100 feet of conductor length the wire size is increased one standard size because of voltage drop.)arrow_forward
