Answer the following statement(s) true (T) or false (F)
1. Diesel, gasoline, or natural gas engine-driven generators are most commonly used to provide another source of emergency or standby power when normal utility power fails. 2. The transfer switch may not be located outdoors. 3. The basic UPS system includes an electronic section that takes the normal line power and converts it to AC power to act as a battery charger. 4. Steam heat, as a waste byproduct of manufacturing processes, is now harnessed and used to turn steam turbine electric alternators. 5.
