Q3 ) A 220-V, 3-o, 4-pole, 50-Hz, Y-connected induction motor is rated 3.73 kW. The equivalent circuit parameters are: R1 = 0.5 2, X1 = 0.6 2, R2' = 0.5 N, X2' = 0.6 2, Xo = 50 Q The stator core loss is 60 W and rotational loss is 120 W. For a slip of 0.04, find: 1) Find (Input current, Induced torque, Efficiency, starting torque)

Estimate the length of conduit to perform the next bends. EMT will be bend using a hand bender. Provide your answer in inches (just the number) using up to 2 decimals. The picture shows two panels connected by a back-to-back 23.5" stubs EMT 3/4" 6.25 ft P

4. Do some search about the functionality of Airport Metal Detectors. Explain your answer in a paragraph.

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. The first support should be installed at the wall. ft ( m) from 4. The second support should be installed at from the wall. ft ( m) 5. The final support should be installed at the wall. ft…
