1. A customer reports that a neighborhood has suddenly lost
electrical service. Several additional calls arrive within five minutes
reporting the same condition. As an Electric Trouble Dispatcher,
what should be the most appropriate initial approach?
A. Immediately dispatch the closest available crew without collecting
additional information
B. Assume the problem is customer-owned equipment because the exact
failure point is unknown
C. Analyze the reports for common location, affected customers,
hazards, and probable system involvement before selecting the
appropriate response
D. Wait until a field crew reports the fault before entering anything into
the dispatch system
Answer: C. Analyze the reports for common location, affected
customers, hazards, and probable system involvement before
selecting the appropriate response
Rationale: A dispatcher must first convert incoming trouble
information into an operational picture. Multiple simultaneous
complaints may indicate a distribution-system problem rather than
isolated customer equipment. Establishing the affected area, potential
hazards, and likely system component helps determine the appropriate
crew, equipment, priority, and operational response. Immediate
1
,dispatch without analysis can waste resources or expose crews to an
incorrectly characterized hazard.
2. A caller reports a downed electrical conductor in a residential
street. Which information should receive the highest immediate
priority during the initial call?
A. The caller's account number
B. The conductor's approximate location, whether it is energized or
arcing, and whether people or vehicles are in immediate danger
C. The caller's preferred restoration time
D. The age of the neighborhood's electrical equipment
Answer: B. The conductor's approximate location, whether it is
energized or arcing, and whether people or vehicles are in
immediate danger
Rationale: A downed conductor represents a potentially severe
electrical hazard. The dispatcher needs enough information to identify
the location and assess immediate life-safety concerns so that the
appropriate emergency response can be initiated. The dispatcher
should not rely on an assumption that a conductor is de-energized
merely because service appears interrupted.
3. A field crew reports that it has arrived at a trouble location but
cannot positively identify the circuit involved. What is the best
dispatcher response?
A. Authorize the crew to operate whichever device appears most likely
to restore service
B. Tell the crew to continue until they identify the circuit independently
C. Obtain and verify the relevant system information and coordinate
with the field crew before authorizing operational actions
2
,D. Cancel the crew because circuit identification is exclusively a field
responsibility
Answer: C. Obtain and verify the relevant system information and
coordinate with the field crew before authorizing operational
actions
Rationale: Accurate circuit identification is fundamental to safe
switching and system control. A dispatcher should reconcile field
observations with available system records, maps, diagrams, and
operational information. Unauthorized or incorrectly directed
switching can interrupt additional customers, damage equipment, or
create dangerous conditions for workers.
4. Why is maintaining accurate computerized trouble-dispatching
information particularly important?
A. It eliminates the need for communication with field personnel
B. It provides an operational record that supports accurate status
tracking, coordination, and subsequent decision-making
C. It allows dispatchers to avoid verifying information received from
crews
D. It primarily serves as a historical database unrelated to current
operations
Answer: B. It provides an operational record that supports accurate
status tracking, coordination, and subsequent decision-making
Rationale: The published Class 3828 duties specifically include
operating computerized electric trouble-dispatching programs and
updating databases. Accurate system information allows dispatchers
and other operational personnel to understand what has been
reported, what actions have occurred, what crews are doing, and what
conditions remain unresolved.
3
, 5. A dispatcher receives conflicting reports from two field crews
regarding the same circuit. What should the dispatcher do first?
A. Choose whichever report arrived first
B. Assume the senior crew is automatically correct
C. Clarify the discrepancy by communicating with the crews and
checking available system information
D. Ignore both reports until a supervisor arrives
Answer: C. Clarify the discrepancy by communicating with the
crews and checking available system information
Rationale: Conflicting information must be reconciled before
consequential operational decisions are made. The dispatcher should
identify exactly what differs, determine the source of each observation,
and compare the reports with available records or system indications.
Acting on an unverified assumption can create unsafe switching or
inaccurate restoration information.
6. Which situation most clearly requires a dispatcher to distinguish
between a customer-side problem and a utility distribution-system
problem?
A. A single customer reports that one appliance is not working
B. One customer reports complete loss of service while neighboring
customers remain energized
C. Hundreds of customers report simultaneous outages in the same
geographic area
D. A customer asks when the next bill will arrive
Answer: B. One customer reports complete loss of service while
neighboring customers remain energized
