CFESA ELECTRICAL PRACTICE TEST|42
QUESTIONS WITH ANSWERS
In order to be used for motor circuits a switch must be rated: - -
- How can you tell if a thermostat is pilot duty? - -
- Solid-state temperature controllers can usually maintain temperature
differentials of_____by cycling the heat off and on as it approaches the
setpoint. - -
- A capacitor start motor should be used in what applications? - -
- You have 120 V super warmer that is not heating. Your meter reads 120 V
from each side of the element to the ground. The voltage across the element
reads 0 V. What is the issue? - -
- A ground fault breaker is considered more reliable than a ground fault
receptacle. T or F? - -
- When removing a thermostat from a piece of equipment that may be
under warranty, it is permissible to cut off the capillary tube to make a faster
repair when: - -
- A thermostat has a differential of 5°F. This means: - -
- A step down transformer is rated at 60 VA. The primary side is connected
to on 120 VAC and the secondary output is 30 VAC. - -
- Wall receptacles failed due to: - -
- Contacts on a contactor that are melted together indicate: - -
- If a neon signal light is shorted: - -
- It is still possible to get shocked by touching the casing of a piece of
equipment if it is properly grounded. T or F? - -
- Before working on electrical equipment with the power on: - -
- Add 240 V range connected to a 208 V power supply will: - -
- AC power has a negative and a positive line. T or F? - -
