it usually depends on which state you are from as to the requirements for becoming a licensed electrican. like here in south carolina you can do elec. work up to $2500 without any type of licenses....go figure..i personally worked in the industrial field for nearly 27 years before going to the construction sector. i could repair mulit-million dollar equipt. but couldn't drive a staple. it's a whole different ballgame but i learned it the hard way. like sparky mentioned the apprenticeship is by far the best way to learn. if you don't want to go that route then maybe take a few courses at a tech school on the construction end..it's like feast or famine, but you are your own boss. so you will work that much harder. good luck! ken m.
