I passed my PE back in Fall 2016. I currently work in the power generation industry of NC. My job doesn't require me to be licensed or to stamp anything. For me, licensure is only required for eligibility of promotion to the upper levels of my position. I've been tossing around the idea of forming a PLLC and starting a side hustle to help supplement my families income. The problem is that I'm having a hard time thinking of what the actual service I would be providing would be. For example, a general contractor or an electrician can pretty much wire a house and outfit it with a circuit breaker panel to code without the need for an engineer to get involved. The same would go for other projects like pool houses, hot tubs, solar, etc. So I guess my question is, what are some real world applications that an Electrical Engineer would be called upon to provide their services? Thanks for any input!
