I would say it's a bad idea depending on the job. Replacing an old plug for a new one with USB, sure why not DIYit. Messing around with the breaker panel to add an electric car charger or an HVAC connection, my recommendation would be to hire a professional. The main issue with AC electricity it's how easy is to learn the basics, and get overconfident because you got something working fast (sadly here I can talk about myself). But not knowing things like the NEC Code makes a difference, and that's when you want a technician or get into the rabbit hole of learning this deeply. Simple details as ignoring the color code, not using the right AWG for the job, can easily cause a fire, or a hidden dangerous electric shock for future maintenance, making the installation a ticking bomb. Again, the right to repair should not be confused with "anyone can do repairs", but having the choice of hiring a 3rd party professional to do the job (or do it yourself if you have the training) outside of the original vendor.
