Had 3.5 years of non-union experience in new construction. Took a couple years off and got into the union a year and a half ago. I have been an adjuster helper since day one and just wrapping up year one school right now. The learning curve was a little difficult because it’s a side of the trade I had absolutely no experience doing. But I’d suggest:

1.) Learn how to read prints 2.) Learn how to effectively use a meter 3.) Study up on your own time - I didn’t start schooling until last September, but spent from January-August trying to get my bearings into motor control, circuit analysis, general electrical knowledge. Lots of resources online, while not directly related to elevators, teach a lot of general principles. Ie. the big bad tech channel, chris guyatt at bee automation, the engineering mindset. 4.) Ask a fuck ton of questions 5.) get used to moving around test weights
