ladder diagram for three circuits, circuit A is one lampholder and one duplex receptacle controlled by a single pole switch, circuit B is a single pole switch controlling the top half of a duplex receptacle that when energized, is indicated by a pilot light at the single pole switch location plus an isolated ground duplex receptacle that is always hot, circuit C is the bottom half of the switched receptacle on circuit B is to be always hot plus another duplex receptacle that is controlled from two locations using coast 3-way wiring system two circuits are 3-wire multiwire branch circuit
2. A facility manager replaces all the TS lights in an office when they have reached 80% of their
rated life of 20,000 hours. The lights operate for 12 hours each day, 5 days per week for 52
weeks of the year. What is the group re-lamping interval for these lights?
a.
3.7 years
b.
4.6 years
c. 5.1 years
d. 6.4 years
Question 3:
Suppose an engineer designed a fire alarm system for a large warehouse, with multiple
pushbutton switches connected to a single alarm siren:
Siren
Actuating any of the normally-open switches results in the alarm sounding. So far, so good.
Now, suppose that one of the wires connecting one side of several switches to the rest of
the circuit breaks open. What will the result of this failure be?
Siren
break!
