Electrical Licensing and Board Rules
Who regulates whom
Colorado electrical work is governed by state statute and the rules of the State Electrical Board. Know the difference between licensing (who may perform work) and registration (an electrical contractor's business registration with the board). A master electrician may hold the qualifying license for a contractor; a journeyman may work only under a master's supervision; an apprentice must be enrolled and supervised. Residential-only licenses carry scope limits that questions love to test.
The traps
- Scope creep: assuming a journeyman can pull permits or contract directly with the public. Generally the contractor (through its master) holds that role.
- Supervision ratios and apprentice registration are rule-based, not code-based. If a question cites ratios, treat it as a board-rule item.
- Reciprocity and exam eligibility hinge on documented hours and verified experience, not self-reporting.
- Discipline: violations can bring fines, suspension, or revocation; unlicensed contracting is itself a violation, even if the work is code-compliant.
Rule of thumb
Ask: Who is legally allowed to do this, and who is legally responsible for it? Licensing answers the first; contractor registration and the qualifying master answer the second.
Worked example
A homeowner asks a journeyman to wire a detached garage as a side job and sign the permit. The journeyman is competent and the installation would pass inspection, but the journeyman is not the registered contractor's qualifying master, so accepting the contract and signing the permit exceeds the license scope. The correct answer is to decline the contract role and work only through a properly registered contractor.
