1. A Meter Setter is preparing to install a self-contained electric
meter on a service where the load is within the meter's direct-
connected rating. What is the primary function of the meter socket
in this installation?
A. To transform the customer's service voltage to a lower metering
voltage
B. To provide a secure mounting and electrical connection point
between the service conductors and the meter
C. To regulate the customer's power factor
D. To provide overcurrent protection for the entire service
Answer: B. To provide a secure mounting and electrical connection
point between the service conductors and the meter
Rationale: A self-contained meter socket provides the physical
mounting and electrical termination interface for a directly connected
meter. It does not itself perform the voltage or current transformation
functions of instrument transformers, nor is it a substitute for service
overcurrent protection. Proper socket configuration, conductor
termination, accessibility, and compatibility with the service are
essential before the meter is installed.

,2. Which condition should cause an Electric Meter Setter to stop
and investigate before installing or reconnecting a meter?
A. The meter enclosure is clean and accessible
B. The service conductors are properly identified
C. There is evidence of damaged insulation or an unsafe energized
condition
D. The customer's load is operating normally
Answer: C. There is evidence of damaged insulation or an unsafe
energized condition
Rationale: Safety takes precedence over completing the meter-setting
task. The Electric Meter Setter classification specifically includes
checking installations for hazardous conditions and testing for voltage
with approved devices. Damaged insulation, exposed energized parts,
improper equipment, or other dangerous conditions must be addressed
according to applicable operating and safety procedures before work
proceeds.
3. Why is a voltage test particularly important before manipulating
conductors or metering equipment?
A. It determines the customer's monthly electric bill
B. It establishes whether potentially hazardous voltage is present
C. It measures the customer's power factor
D. It determines the mechanical condition of the meter register
Answer: B. It establishes whether potentially hazardous voltage is
present
Rationale: Voltage testing is a fundamental electrical-safety
procedure. A circuit that is assumed to be de-energized must not be
treated as safe merely because a disconnect is open or someone states
that power has been removed. An approved tester, used according to
2
,established procedures, provides objective information about the
presence or absence of voltage.
4. An installation uses current transformers because the customer's
current exceeds the practical direct-connection capability of the
meter. What is the principal purpose of the CTs?
A. To increase line voltage
B. To provide a proportional current for the metering circuit
C. To disconnect the customer's service automatically
D. To eliminate the need for a meter socket
Answer: B. To provide a proportional current for the metering
circuit
Rationale: A current transformer, or CT, reproduces a proportional
representation of primary current on its secondary side so that the
metering equipment can measure large currents without carrying the
full service current through the meter itself. CT installations require
correct polarity, ratio, wiring, and associated metering equipment.
LADWP's Electric Meter Setter classification specifically identifies
current transformers as metering equipment that setters install.
5. A Meter Setter encounters an instrument-transformer-rated
meter socket. Which statement best describes the customer wiring
requirement under LADWP's Electric Service Requirements?
A. The customer must connect all conductors directly to the meter
socket terminals
B. The customer must bypass the CTs
C. The customer shall not connect conductors to the socket terminals for
an instrument-transformer-rated meter installation
3
, D. The customer must install an additional meter between the CTs and
the socket
Answer: C. The customer shall not connect conductors to the socket
terminals for an instrument-transformer-rated meter installation
Rationale: LADWP's 2024 Electric Service Requirements specifically
distinguishes self-contained and instrument-transformer-rated
metering. For instrument-transformer-rated installations, customer
conductors are not to be connected to the meter socket terminals in the
manner used for self-contained installations. The distinction is
important because the metering circuit incorporates instrument
transformers and associated equipment.
6. What is the most important reason for verifying the meter
number before removing or installing a meter at a commercial
property?
A. To determine the customer's preferred billing date
B. To ensure the correct meter is associated with the correct service
C. To determine the conductor insulation temperature rating
D. To calculate transformer efficiency
Answer: B. To ensure the correct meter is associated with the
correct service
Rationale: Meter identification is a critical control against
misregistration and incorrect service work. LADWP's customer
information specifically instructs users to verify the meter number
when determining the correct meter. For a Meter Setter, accurate
identification becomes even more important when multiple meters are
grouped together or when commercial metering equipment is complex.
