Occupations: electricians; ratio of electrician apprentices to journey or master licensees on a jobsite; modify, and require joint responsibility for supervision between electrical contractors and master electricians. Amends secs. 701, 711, 715 & 717 of 2016 PA 407 (MCL 339.5701 et seq.).

SB 72 modifies Michigan's electrical licensing rules to clarify supervision responsibilities. It requires electrical contractors to have a master electrician actively overseeing all electrical work, and both the contractor and master electrician share joint responsibility for ensuring compliance with electrical codes. If a master electrician leaves, contractors must hire a replacement within 30 days and notify the licensing department. This directly affects electrical contractors and master electricians who manage jobsites, ensuring consistent on-site supervision of electrical installations. The bill does not change licensing requirements for apprentices or journeyman electricians.
