What does the Colorado Electrical Contractor license require?

Electrical contractor registration (not a license): the owner or a full-time employee must be a Colorado master electrician, and a master can be the named master for only one contractor. Individual licenses: Master, Journeyman, Residential Wireman; plus apprentice registration.1

Exam

Master, Journeyman and Residential Wireman license exams are set and graded by the Board, which sets the passing score.1

Bond

No surety bond is required for contractor registration (CRS 12-115-110(5) asks only for the fee, workers' comp and unemployment compliance, and a master electrician).1
