Answer the following statement(s) true (T) or false (F)
1. DC motors are most common in residential applications and include most household applications such as garbage disposal motors, furnace blower motors and air-conditioning compressor motors. 2. As the motor is installed, the nameplate information is needed to properly install the motor in a safe and efficient matter. 3. A general-use snap switch may not be used as a controller if it has an ampere rating that is more than twice the full-load current rating of the motor. 4. Electricians typically connect the branch-circuit power and the local disconnect (a switch) for the furnace power, and all the rest of the controls for the fan are external to the furnace controls. 5. Most DC motor installations recently installed have electronic controls in which much of the overload protection is part of the solid-state control circuitry.
