Do you need a license to do electrical work in Wisconsin?
Yes. In Wisconsin, installing, repairing or maintaining electrical wiring requires a state electrician license or registration, and a business doing that work needs a state electrical contractor license. Licenses are issued by the Department of Safety and Professional Services, and anyone who is not a master electrician must work under a master electrician who is at all times responsible for the work. A residential property owner working on premises the owner owns and occupies as a residence is exempt unless a local ordinance requires a license. This is Wis. Stat. §§ 101.862, 101.01.
