Oh, and by the way: In Colorado
Resedential Wireman: 2 years - 4000 documented hours as a REGISTERED apprentice. Anything undocumented does not count.
This allows you to take a 4 hour 90 question test that 80% fail the first time around (???) If you pass, this allows you to supervise residential jobs only, and make up to $25 / hr. Most get around $21
Journeyman Wireman: 4 years - 8000 documented hours as a REGISTERED apprentice. Must have at least 4000 hours as commercial experience.
This allows you to take a 4 hour 90 question test that over 1/2 fail the first time around. (Still don't know why...) Once you pass that, this allows you to work unsupervised on any jobsite. Wages: $21-$25 / hr. Good ones make $28 / hr.
Master Electrician: 1 year of documented supervision after you have completed your Journeyman's license. Again... 4 hour 90 question test. Very similar to Journeyman's... more calculations... Wages... about the same as J-man.
Electrical Contractor: Master's license + Insurance + Business License. This allows you to talk to the local RBDs.
Register in most RBDs cost $0 (Colorado Springs) to $200 (Denver). By the way, Denver has 4 RBDs...
Side note: Arapahoe Road used to be dividing line: If you had 2 jobs, one on each side, you would need 2 inspectors, and 2 RBD registrations.
Now you can pull a permit...
Lets get to work while the day is young...
In Colorado Springs, there are ~500,000 people (surrounding areas too) and over 154 registered ECs. No telling how many non registered Journeymen doing side work.
