But, if you are an electrician who does all residential, in PVC or NMB mostly, and can understand the code book, plus have passed the basic tests, but yet are not knowledgeable in motor theory, trailer parks, modular homes, marinas, or high voltage and do not work in those areas either, should you be required to learn those before being licensed as a residential electrician?
Yeah its two years +/- of on the job training Plus night school two night a week (IBEW or IEC) and not an easy test. But you don't need the training commercial guys need like how size motor control feeders, work in hazardous locations, hospitals, airports etc (other than agricultural buildings i suppose) , or stuff like that.
In Oregon you can come here and take the Residential JW test and (CA and WA) are similar with legally verified 8000 hours OJT working for a licensed electrician from out of state or country. In state apprentices need 4000 hours plus the state approved apprenticeship of two years.
Then you can get a job making 25 - 45 per hour crawling in attics and under all the stick built 1940's houses pulling new romex. CA to the south and WA to the north have very similar systems. After you get a few years as a residential ( I forget what it is ) you can take the JW test.
