What qualifications do you need to be a low voltage contractor in Maryland?

I have my FSR ticket (Field Safety Representative) here in BC. I've had to take numerous courses, have over 1800 pre-wire hours of working under a licensed FSR before be able to challenge the test.

I can pull my own permits, I can run my own 110v branch circuits and even home runs when needed. I can even walk onto a job site, see something wrong being done, and shut down the job site. I'm limited to under 600 volts.

I can't wire a house for 110v. When I need an electrician, I bring one in. I haven't had many issues with electricians but maybe just lucky.

This reminds me of years ago in Ontario, they were trying to get a law passed so that you had to be a journeyman mechanic to install a car stereo. Didn't happen when most mechanics had no desire to install a stereo.
