Directing the department of labor and industries to adopt rules clarifying the scope of work for HVAC/refrigeration specialty electricians for ductless mini-split systems.

SB 6112 directs Washington's Department of Labor & Industries to adopt rules clarifying that HVAC/refrigeration specialty electricians may perform specific electrical connections for ductless mini-split HVAC systems. The bill allows these certified electricians to install, repair, or maintain wiring between indoor and outdoor units when following manufacturer instructions and using equipment certified by accredited labs. This change specifically covers the electrical work integral to the system (like circuits and wiring), not broader electrical tasks, and includes safety conditions like voltage limits. The rulemaking aims to reduce installation delays and costs while maintaining safety standards for residential and light commercial systems. The bill does not alter general electrical licensing or safety codes.
