Textbook Question
Chapter 26, Problem 16R
Circle the correct answer from the following statements:
- a. Always connect a fire alarm circuit or system to a power supply that has ground-fault circuit interrupter (GFCI) protection.
- b. Never connect a fire alarm circuit or system to a power supply that has ground-fault circuit interrupter (GFCI) protection.
- c. It makes no difference whether the branch circuit is GFCI or AFCI protected because the alarms are required to have battery backup power. In the event of a loss of power for whatever reason, the alarms would still be operative.

Select one:
A. BREAKERS LOCATED IN THE SERVICE PANEL
B. BREAKERS LOCATED AT THE OVERLOAD
C. FUSES LOCATED IN THE BUS PLUGS
D. FUSES LOCATED AT THE DISCONNECT
Do not worry about "box fill" when working with dimmer and speed control devices. They are about the same size as regular wall switches.
