Calculate the daily efficiency of a single-phase transformer with an output capacity of 350 kVA at full load. If the losses of core and copper at full load are equal to 4.2 kW and 3.2 kW, respectively. If the transformer works during the day as follows: (1) Six hours at full pregnancy and at a factor of 0.85) lag. (ii) Three hours at three quarters of full load and with a power factor of 0.8 delayed. (iii) Six hours at a quarter of the full load and an amount of one is treated. (iv) Four hours at one fifth of full pregnancy and by a factor of one.

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3.
