I have two fears: Can a 46 year old body handle the Electrical 1st year's apprentice's duties: digging ditches, digging post holes, etc? Will a 46 year old apprentice get laughed off the job site?
Thanks for any insights.
A lot of it will just depend on luck. All electrical work is not the same and all crews are not the same. I was once the oldest guy working on a crew at age 35. I didn't really feel at home working with a bunch of young journeymen. A year later I was working with a different crew and had a 55 year old helper.
You can either end up broiling in the sun or freezing to death on a different job. You may never dig the first hole or that may be all you do.
If you end up training with a company that can find work more suited to your experience you may not have much trouble at all. There are shops that do nothing but communications and data wiring they don't even touch the power side. Another thing to look at is control work and industrial maintenance. The work isn't as hard as rough construction and requires a little more intelligence and training than rough construction.
If I were you I wouldn't be so quick to throw away the the experience and training that you allready have but use what you know to find something comparable in the electrical field. There are plenty of electrical jobs that are not all grunt work but still let you work with your hands. A software engineer shouldn't have any trouble learing to program a PLC. Use what you have, there are lots of strong backs and weak minds outs there so don't try to compete against them. All electrical work doesn't require the use of a shovel.
