- The hot water for the heating system for a small factory is supplied by a single boiler. The bolier is locatd in a small building separate form the factory. The power supplied to the bioler is 240-volt single-phase without a netural conductor. At the present time, the small building housing the bioler has no inside lighting. The business owner desires that four 100-watt lamps be installed inside the building. All lamps are to be connected to a single switch. The lamps are to be connected to the present 240-volt sercvice inside the building. How would you accomplish this task? Explain your answer.arrow_forwarda. When more than three current-carrying conductors are installed in one raceway, their allowable ampacities must be reduced according to NEC __________. b. The following is a project. We need four 15-ampere branch circuits. We will use two 3-wire multiwire branch circuits and 14 AWG THHN conductors. We will install the conductors in EMT. The room temperature will not exceed 86F (30C). The connected load is nonmotor and is noncontinuous. 1. What is the minimum trade size EMT? __________ 2. What is the ampacity of the conductors before derating? __________ 3. What is the ampacity of the conductors after derating? __________ 4. What is the maximum overcurrent protection permitted for these conductors? __________ c. Lets increase the conductor size to 12 AWG THHN for the same installation to see what happens. 1. What is the minimum trade size EMT? __________ 2. What is the ampacity of the conductors before derating? __________ 3. What is the ampacity of the conductors after derating? __________ 4. What is the maximum overcurrent protection permitted for these conductors? __________ d. It (is) (is not) necessary to count equipment grounding conductors, a neutral conductor that carries the unbalanced current from other conductors of the same circuit, and/or travelers when installing 3-way and 4-way switches for the purposes of derating the ampacity of these conductors.
