Understanding how to wire a circuit properly is not nearly as complicated as learning to drive a car (as well as learning the vehicle code that you're agreeing to abide by). And statistically driving is FAR more dangerous than working on household electrical circuits.Electricity can get pretty complicated, i would rather pay someone to do it right then spend my time trying to learn something that i know absolutely nothing about and potentially mess up the electricity to my house or even kill me
And yet... we give away driver's licenses without expecting much of anything. And then we basically never retest for a lifetime.
It truly amazes me what we're scared of vs. the real risks we take for granted in our everyday lives.
