I attended a 8 hour CEU class just on health care years ago before I started working at a large hospital. Unfortunately the NJ based company that held them went out of business. Liked attending the 8 yearly great local IAEI meetings that always had very interesting two hours of CEU'S. Even though a few of them were not on any work that I would work on. I always turned down installing power on built in swimming pools due to life long liability issues even though I carried ample insurance but found the CEU'S for pools very interesting. Was fortunate to be at two IAEI classes that Mike Holt was the presenter. Both had triple the number of regular attendees.Unfortunately yes. There are a limited amount of approved courses. Mostly they are code update courses and changes in state departments have taken a toll on how often a new NEC edition gets approved. The state used to approve new editions almost concurrently with their publication. We're still on 2017 with no clear announcement for a new adoption, but they are working on it.
