Alaska statutes are clear. Installation done per the NEC require a Certificate of Fitness (journeyman's license)
Putting in a new 120V receptacle requires a COF.
To replace a 2200 hp, 4000 V motor, OSHA requires "qualified" - short, paraphrased definition, "Trained on the equipment and task."
Truly, there are not many COF holder house ropers I want terminating a 4160V motor. That is not dising house ropers, it is just not what they are trained on.
(edit to add)
Alaska does not require a COF to wire one's own house.
And, I understand, Anchorage requires a plumber license (mechanical administrator?) to install a water heater - even in one's own house. Not sure on this, The only place I visit in Anchorage is the airport.
