(b) The classification or type of facility to be inspected and the exact scope and location of the electrical work to be performed are clearly shown on the electrical work permit;
(c) The address where the inspection is to be made is clearly identifiable from the street, road or highway that serves the premises; and
(d) Driving directions and/or a legible map must be provided for the inspectors' use.
(2) Final inspection approval will not be made until all inspection fees are paid in full.
(3) An electrical work permit is valid for only one specific site address.
(4) A valid electrical work permit must be posted on the job site at a readily accessible and conspicuous location prior to beginning electrical work and at all times until the electrical inspection process is completed.
(5) Except for emergency repairs to existing electrical systems, electrical work permits must be obtained and posted at the job site prior to beginning the installation or alteration. An electrical work permit for emergency repairs to existing electrical systems must be obtained and posted at the job site no later than the next business day after the work is begun.
(6) Electrical work permits will expire one year after the date of purchase unless electrical work is actively and consistently in progress and inspections requested. Refunds are not available for expired electrical work permits or for electrical work permits where the electrical installation has begun, or an electrical inspection or electrical inspection request has been made.
(7) Fees must be paid in accordance with the inspection fee schedule, WAC 296-46A-910.
(8) Each person, firm, partnership, corporation, or other entity must furnish a valid electrical work permit for the installation, alteration, or other electrical work performed or to be performed by that entity. Each electrical work permit application must be signed by the electrical contractor's administrator (or designee) or the person, or authorized representative of the firm, partnership, corporation, or other entity that is performing the electrical installation or alteration. Permits purchased electronically do not require a handwritten signature. An entity designated to sign electrical permits must provide written authorization of the purchaser's designation when requested by the department.
(9) When allowed by the chief electrical inspector, annual permits for the inspection of telecommunications installations may be purchased by a building owner or licensed electrical/telecommunications contractor. Telecommunications work may be done under this annual permit by the building owner, the owner's regular employees, or a licensed electrical/telecommunications contractor. The permit holder is responsible for correcting all installation deficiencies. The permit holder must make available to the electrical inspector records of all the telecommunications work performed and the valid electrical or telecommunications contractor license numbers for all contractors working under the permit.
(10) Permits to be obtained by customers. Whenever a serving electrical utility performs work for a customer under one of the exemptions in WAC 296-46A-935 and the work is subject to inspection, the customer is responsible for obtaining all required permits.
(11) As required by chapter 19.28 RCW or this chapter, an electrical work permit is required for the installation, alteration, or maintenance of electrical systems except for: Plug-in appliances, travel trailers, or like-in-kind replacement of a: Circuit breaker, fuse, lamp, snap switch, receptacle outlet, heating element, lighting fixture ballast with an exact same ballast, contactor, relay, timer, starter, similar control component, or motor.
(12) An electrical work permit is required for all installations of telecommunications systems on the customer side of the network demarcation point for projects greater than ten telecommunications outlets. All backbone installations regardless of size and all telecommunications cable or equipment installations involving penetrations of fire barriers or passing through hazardous locations require permits and inspections. For the purposes of determining the inspection threshold for telecommunications projects greater than ten outlets, the following will apply:
(a) An outlet is the combination of jacks and mounting hardware for those jacks, along with the associated cable and telecommunications closet terminations, that serves one workstation. In counting outlets to determine the inspection threshold, one outlet must not be associated with more than six standard four-pair cables or more than one twenty-five-pair cable. Therefore, installations of greater than sixty four-pair cables or ten twenty-five-pair cables require permits and inspections. (It is not the intent of the statute to allow large masses of cables to be run to workstations or spaces serving telecommunications equipment without inspection. Proper cable support and proper loading of building structural elements are safety concerns. When considering total associated cables, the telecommunications availability at one workstation may count as more than one outlet.)
(b) The installation of greater than ten outlets and the associated cables along any horizontal pathway from a telecommunications closet to work areas during any continuous ninety-day period requires a permit and inspection.
(c) All telecommunications installations within the residential dwelling units of single-family, duplex, and multifamily dwellings do not require permits or inspections. In residential multifamily dwellings, permits and inspections are required for all backbone installations, all fire barrier penetrations, and installations of greater than ten outlets in common areas.
(d) No permits or inspections are required for installation or replacement of cord and plug connected telecommunications equipment or for patch cord and jumper cross-connected equipment.
(e) Definitions of telecommunications technical terms will come from chapter 19.28 RCW or the currently adopted rules, EIA/TIA standards, and NEC.
(13) Requests for inspections must be made no later than three business days after completion of the electrical/telecommunications installation or one business day after any part of the installation has been energized, whichever occurs first. Inspections for annual electrical maintenance permits and annual telecommunications permits may be done on a regular schedule arranged by the permit holder with the department.
