1.21 Clearance to Existing Lines
Tillamook PUD’s goal is to ensure your project worksite is as safe as
possible for both the public and its employees. The High Voltage Overhead
Line Safety Act in part states the following:
1.21.1
Restricted Space
“For lines rated between 600 volts and 50 kV, the restricted
space extends 10 feet in all directions from the surface of the
line or equipment.
For lines rated over 50 kV, the restricted space extends 10
feet plus 0.4 inch for each 1 kV over 50 kV, or twice the length
of the insulator (but never less than 10 feet) in all directions
from the surface of the line or equipment.”
1.21.2
General Requirements
Do not enter or perform any function or activity (such as
handling, erecting, operating, transporting, and storing tools,
equipment, materials, and moving a building or structure)
within the restricted space surrounding an overhead highvoltage line or equipment unless proper notification is provided
to Tillamook PUD and the line and/or equipment is deenergized and visibly grounded by Tillamook PUD.
If a violation occurs, Tillamook PUD will request a stop work
order from the Tillamook County Community Development
Department. Work will not be allowed to resume until an
agreement is reached for construction to resume safely.

Area Lights
7.1
General
Tillamook PUD provides area lighting and public street lighting for
customers located within the Tillamook PUD service territory.
Lights provided are high-pressure sodium-type in the 100- and 200-watt
sizes. Wide-angle, high-pressure sodium lights are available in 200- and
400-watt sizes. Lighting provided by developers must meet Tillamook
PUD specifications and policies.
To request area lighting, contact the Tillamook PUD Engineering
Department. Once the necessary information is received, a Tillamook
PUD Engineering Field Representative will visit the proposed location to
determine if existing facilities are adequate or if additional facilities will be
required to serve the light (poles, conductor, or transformers).
If additional facilities are required to serve the light installation, costs will
be at the customer’s expense as specified in Tillamook PUD Policy
Bulletin 4-2.
Tillamook PUD requires the customer sign a one-year contract obligating
payment of a monthly service fee. The customer shall allow Tillamook
PUD free access to the customer’s property to inspect and maintain the
equipment or to remove the installation upon termination of service.
The customer shall exercise care to prevent damage to lighting fixtures.
Every effort shall be made to minimize the impact of light pollution on
neighboring properties.
The customer shall not place customer-owned area lighting on Tillamook
PUD-owned poles. The customer has the option of providing and
installing an area lighting system, provided service to these electrical
facilities is connected behind an approved disconnect.
The monthly billing of customer-owned area lighting will be a flat rate
schedule based on the connected load. Ownership and maintenance of the
complete lighting system behind the approved disconnect will remain the
responsibility of the owner.

Generation—
Permanent and Temporary
9.1
Generator Safety
When any of the types of generation systems defined below are used, they
must be isolated from Tillamook PUD facilities to prevent serious danger
to Tillamook PUD personnel and damage to customer property. To assure
the safety of TPUD personnel and to avoid potential damage to customer
property when portable generators are used, all electrically-operated
devices shall be connected directly to the portable generator or approved
transfer switch.
Never overload the generator. Always operate the generator in
accordance with the manufacturer’s recommendations.
Never try to power the house wiring by plugging the generator into
a wall outlet, a practice known as “backfeeding.” This is an
extremely dangerous practice that presents an electrocution risk to
utility workers and neighbors served by the same utility
transformer. Backfeeding also presents a serious risk of damaging
the generator, owner’s property, and neighboring properties. It
also bypasses some of the built-in household protection devices.
Never operate the generator inside your home. Good ventilation is
important. Generators produce carbon monoxide, a colorless, odorless,
toxic gas that can result in serious injuries, or even death, if levels become
too high.
9.2
Portable Generators
The simplest way to use a portable generator is to plug appliances directly
into the generator. A heavy-duty, outdoor-rated extension cord can be
used but it should be rated (in watts or amps) at least equal to the sum of
the connected appliance loads.
9.3
Fixed Generators
The only approved method to connect a generator to building wiring is by
having a qualified electrician install a transfer switch. The transfer switch
is installed between the generator and the electrical panel. It allows
power to be fed from only one source at a time.
TILLAMOOK PUD ELECTRIC SERVICE REQUIREMENTS
MARCH 2008

This switch must be installed in accordance with the National Electrical
Code (NEC), which is published by the National Fire Protection
Association, and all applicable state and local electrical codes.
An electrical permit must be obtained from the Tillamook County
Department of Community Development and the installation must be
inspected and approved by the Oregon State Electrical Inspector prior to
operation.
