FAQs
Do I have to register as an electrical apprentice in Colorado?
Yes. State law requires it, and your employer has to file the registration within 30 days of your first day. You get a registration number that stays with you through every job change, and you have to carry the card while working.
Do I need a license to work as an electrician in Colorado?
You need a license to work unsupervised. Residential wireman, journeyman, and master are all licensed by the State Electrical Board. Apprentices are registered rather than licensed, and work under direct supervision.
How long does it take to become a journeyman electrician in Colorado?
At least four years. The state asks for 8,000 hours earned over no less than four years, plus 288 classroom hours. The four-year minimum holds even if you bank the hours faster.
How many of my hours have to be commercial or industrial?
The state is not consistent on this. The Board’s licensing page says 2,000 hours, while Colorado law asks for two years or 4,000 hours. Plan for the higher figure and confirm with the Board before you commit to a schedule.
Does Colorado accept an electrician license from another state?
Yes, for journeymen from the 14 National Electrical Reciprocal Alliance states: Alaska, Arkansas, Idaho, Iowa, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, and Wyoming. You need to have held it a year and earned it by exam. Master electricians use the endorsement route instead.
How often do Colorado electrician licenses renew?
Every three years, on September 30. Renewal requires 24 hours of continuing education from a Board-attested provider. If you were licensed by exam during the current period, you skip continuing education until after your first renewal.
Can I become a master electrician without being a journeyman first?
Not on experience alone. Colorado does not let you go from apprentice or residential wireman straight to master that way. A degree can open other routes in, but the ladder generally runs through journeyman.
Do I need a separate license to install solar in Colorado?
A 2025 state law requires photovoltaic installation companies to register with the State Electrical Board by December 31, 2026, and to employ at least one NABCEP-certified person. That registration sits with the company rather than with you as an individual.
