Section 7 Area Lights 7.1 General Tillamook PUD provides area lighting and public street lighting for customers located within Tillamook PUD s service territory. Currently, the lights provided are dark-sky compliant fixtures in standard output LED and high output LED sizes. Lighting provided by developers must meet Tillamook PUD specifications and policies. To request area lighting, contact 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. TILLAMOOK PUD ELECTRIC SERVICE REQUIREMENTS 7-1

Section 9 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 Tillamook PUD personnel and to avoid potential damage to customer property when portable generators are used, all electricallyoperated 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 attempt 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 9-1

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.
