This bill directs the Department of Labor and Industries to adopt rules that clarify the scope of work for HVAC/refrigeration specialty electricians specifically regarding ductless mini-split heating, ventilation, and air conditioning systems. The legislation recognizes the growing demand for these systems due to their efficiency and the influence of state energy codes. It emphasizes that electricians with the HVAC/refrigeration specialty certification are qualified to perform electrical connections between the outdoor and indoor units of mini-split systems, provided these connections adhere to manufacturer specifications and safety standards.

The bill establishes a new section in chapter 19.28 RCW, detailing the responsibilities of the Department of Labor and Industries in defining the scope of work for certified HVAC/refrigeration specialty electricians. It allows these electricians to install, repair, replace, and maintain electrical connections between mini-split system components, as long as the work complies with specific conditions, including adherence to manufacturer instructions and the use of certified equipment. Additionally, the department is granted the authority to set reasonable limitations on various factors related to the electrical work, while ensuring that the rules do not restrict the electricians from performing the authorized tasks.
