and appliances.
3. A GFCI outlet is designed to:
A. Protect against power surges
B. Protect users from ground faults
C. Regulate amperage flow
D. Provide additional voltage
GFCI detects imbalances between hot and neutral conductors to prevent
electric shock.
,4. The term “amp-hour rating” refers to:
A. Voltage capacity
B. Battery storage capacity over time
C. Instantaneous current draw
D. Inverter efficiency
Amp-hours measure how many amps a battery can deliver in one hour.

system?
A. 30 psi
B. 5 psi
C. 11 inches water column (WC)
D. 20 inches WC
The second-stage regulator reduces pressure to 11 inches WC for safe
appliance operation.
6. What tool is used to check LP gas leaks in RV systems?
A. Flashlight
B. Multimeter
C. Soapy water solution or leak-detector spray
D. Wrench
Soap bubbles form at leak points when pressure is applied.

1. (Electrical Systems) What is the primary purpose of an RV inverter?
A. Convert AC to DC
B. Convert DC to AC
C. Store electrical energy
D. Regulate voltage
Correct Answer: B
Rationale: An inverter converts 12V DC battery power into 120V AC power.
2. (LP Gas Systems) Why are LP gas detectors installed near the floor?
A. Heat rises
B. Propane is lighter than air
C. Propane is heavier than air
D. Easier installation
Correct Answer: C
Rationale: Propane is heavier than air and settles near the floor.
