LADWP Electric Service Planning ESR Book Section 1 Study
Guide 2026 | Complete Review | Graded A+
1. If a business applies for electrical service but is found to have an insufficient
load, what steps should they take to ensure service is provided?
They should reimburse the department for the excess investment
needed.
They should reduce their electrical load requirements.
They should apply for a different type of service.
They should wait for the department to approve their application.
2. What must a customer do if their electrical load is deemed insufficient?
Provide additional documentation
Wait for the department to invest
Increase their electrical load
Reimburse for excess investment needed
3. If a new electrical service installation fails the final department inspection,
what steps should be taken before the service can be energized?
Contact the customer to inform them of the delay without taking
further action.
Address the issues identified during the inspection and schedule a
re-inspection.
Proceed to energize the service regardless of the inspection results.
Remove all equipment and start the installation process over.
,4. What is the minimum power factor required for gaseous tube lighting
equipment that has a rating of 15 watts or higher?
90-percent lagging or leading
80-percent lagging
100-percent lagging
75-percent leading
5. Describe the importance of load characteristics in electric service
applications.
Load characteristics only apply to commercial services.
Load characteristics are used for billing purposes only.
Load characteristics help determine the appropriate electrical
service needed for the customer.
Load characteristics are irrelevant to service applications.
6. In a scenario where a new customer is planning to install high-capacity
equipment that may affect voltage stability, what should the service planning
office consider?
The potential need for separate service or equipment to mitigate
voltage fluctuations.
The overall increase in energy tariffs for all customers.
The customer's request for expedited service installation.
The historical load characteristics of neighboring customers.
7. What is the acceptable voltage range for 480 volts?
460 - 520 volts
, 450 - 490 volts
400 - 500 volts
440 - 508 volts
8. If a customer fails to install the facilities as specified in the construction
drawings for an underground project, what potential consequence might
they face?
Delays in service activation.
Immediate energization of the service.
Reduction in installation costs.
Approval for additional services.
9. If a customer has paid all fees but one inspection is still pending, what is the
status of their electric service activation?
The electric service can be energized.
The electric service will be energized after the next billing cycle.
The electric service cannot be energized.
The electric service is partially energized.
10. What classification is given to machines, high voltage testing equipment, and
electric welders according to the document?
Standard Equipment
General Equipment
Special Equipment
Auxiliary Equipment
, 11. If a business requires an electrical installation to be completed on a weekend
to avoid disruption during regular hours, which service option should they
request?
Routine maintenance service
Premium time installation
Standard installation
Emergency repair service
12. What type of voltage may the department require when service is supplied
from dedicated transformers on the customer's premises?
Two-wire split-phase voltage
Four-wire wye voltage
Three-phase delta voltage
Single-phase voltage
13. Describe the regulations that apply to Special Equipment as mentioned in
the document.
Special Equipment must be inspected annually without exception.
Special Equipment can operate independently of department rules.
Special Equipment is exempt from all regulations.
Special Equipment is subject to department rules regulating
connected loads and maximum demand.
14. If a customer submits electrical plans without equipment elevation drawings,
what potential issue might arise during the installation of their electric
service?
