EES 102 Week 09

When there are six or more circuits in an RV, the minimum power supply assembly is a

• 30-amp without an energy management system

• 50-amp distribution panel

• two 120-volt circuits

• 30-amp with energy management system

The PDI of the 120 VAC electrical system will include the following:

• Inspecting the shoreline cable

• Conducting a hot skin test

• Inspecting circuit breakers

• Testing/measuring GFCI circuits, circuit breakers, and

  outlets

• All of the above

Place one voltmeter probe on a bare metal surface of

the RV (e.g., a door frame) and the other probe on

(a)an ________ source (e.g., a water pipe)

• Chassis Ground

• Battery Positive

• Battery Negative

• Earth Ground

A battery hydrometer is used to measure _________ of a battery

• charge level

• specific gravity

• electrolyte stability

• chemical balance

Relating to RV wiring, any area accessible to the RV owner for storage or in a traffic area is considered to be

• acceptable for uncovered RV wiring

• acceptable for RV wiring as long as it is covered/protected

• unacceptable if RV wiring is present

• subject to physical damage in outside compartments only

Which of the following is NOT a type of energy management system (EMS)

• manual

• automatic

• programmable

• on-demand

If an RV with a 30-amp power supply has more than two 120-VAC thermostatically controlled appliances, what must be done?

• An extra circuit breaker must be installed

• An energy management system must be used

• Nothing, no action is needed

• Only one of the controlled appliances can be used at a time

Exterior receptacles are required to

• only have a weather-proof cover

• be protected by a GFCI device

• be on an isolated circuit

• to be the only receptacle

Exterior receptacles must have

• a cover that opens up

• a cover that opens down

• a wet location cover

• a weather-proof gasket

What is the function of an energy management system?

• optimize generator efficiency

• optimize 12 VDC distribution

• optimize 120 VAC distribution

• optimize inverter efficiency
