This bill directs the Department of Labor and Industries in Washington 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 safely 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 introduces a new section to chapter 19.28 RCW, outlining that the Department of Labor and Industries must establish rules that permit certified HVAC/refrigeration specialty electricians to install, repair, replace, and maintain electrical connections for mini-split systems. The rules will ensure that the work is performed according to manufacturer instructions and that the equipment is certified by an accredited testing laboratory. Additionally, the department may set reasonable limitations on various factors such as voltage and building occupancy to ensure public safety, while maintaining the authority to regulate electrical work and enforce compliance with existing electrical codes.
