I have to get CEUs to maintain my PE. There seems to have developed a business of holding expensive seminars to spend time to collect hours for your CEUs.
The objective is the hours and the seminar doesn't always relate to teaching you anything you didn't already know. The focus is on paying some guy a lot of money to make PowerPoint presentations for $400 to $600 per day (which is usually about 6 hours).
Since I am mostly retired but want to maintain my license, and don't have an employer to pay for CEU seminars, I shop around. I find the university correspondence courses are pretty economical and quite good. I got my last three from the University of Wisconsin.
For electricians, you might want to look at community colleges or vocational schools. If you are employed at a substantial company, maybe they will cover costs. You might have time to negotiate that with your employer if there are a lot of you.
Another possibility would be to get your employer to conduct training in the company for several people. They could keep records of that training and certify that people have earned the hours and CEUs.
If your employer will pay the tuition for a college course, you can often get all the CEUs you need for a renewal cycle from a single course.
