Preproposal statement of inquiry was filed as WSR 98-13-123.

Title of Rule: Chapter 296-46 WAC, Safety standards--Installing electrical wires and equipment--Administrative rules; and chapter 296-401A WAC, Certification of competency for journeyman electricians.

Purpose: Chapter 296-46 WAC, Safety standards--Installing electrical wires and equipment--Administrative rules, National Electrical Code (NEC) initiated proposed amendments to chapter 296-46 WAC, Safety standards--Installing electrical wires and equipment--Administrative rules, are made to be at least as effective as the 1999 NEC code. According to RCW 19.28.060, the department, in conjunction with the Electrical Board, is required to adopt reasonable rules based upon the latest revision of the NEC code. These NEC-initiated proposed amendments will not establish any additional compliance requirements.

WAC 296-46-090 Forward, the proposed amendments adopt the 1999 edition of the NEC codes and standards as the minimum standard for electrical installations in Washington.

Department-initiated proposed amendments to chapter 296-46 WAC, Safety standards--Installing electrical wires and equipment--Administrative rules, are being made to comply with RCW 19.28.060 which requires the department, in conjunction with the Electrical Board, to adopt "reasonable rules to ensure safety to life and property." These proposed amendments establish additional compliance requirements.

WAC 296-46-23040 Service conductors, the proposed amendment clarifies that multiple service laterals must terminate in listed service equipment, including listed metering or service accessory equipment.

WAC 296-46-370 Boxes and fittings, the proposed provision will allow conductors rated for wet locations to terminate in designated direct burial open-bottom junction boxes. The junction boxes shall be rated for not less than H-10 loading and have a metal cover to identify it as electrical.

WAC 296-46-495 Electrical work permits and fees, the proposed provision requires that an electrical inspection must be requested no later than the first business day after completion of the electrical installation or after any part of the installation has been energized, whichever occurs first.

WAC 296-46-50002 On-site sewage disposal systems, the proposed amendment clarifies that structure plumbing vents, approved by the local jurisdiction authority, shall constitute adequate venting of the septic system pumping chamber.

WAC 296-46-930 Electrical contractor license and administrator certificate designation, in order to be in compliance with RCW 19.28.120, this proposed provision creates a new limited energy electrical contractor license and administrator certificate for work performed on HVAC/refrigeration limited energy control circuits. Contractors who provide proof they were engaged full time in the business of performing HVAC/refrigeration limited energy installations will be allowed to designate a supervisory employee or member of the firm to take the administrator examination.

The following legislative-initiated proposed amendments to chapter 296-46 WAC, Safety standards--Installing electrical wires and equipment--Administrative rules, are being made to comply with 1998 amendments to RCW 26.23.120:

WAC 296-46-940(1) electrical contractor license, the proposed provision requires that an electrical contractor (sole proprietor or partnership only) must submit his or her Social Security number, date of birth and mailing address prior to issuance or renewal of an electrical contractor license.
