Most people have no idea what to ask an electrician for. Start with what it is doing.
Each one is a page rather than a paragraph, because each one is a different conversation with a different worry underneath it.

The questions that do not fit on one page.
Real questions off the forums and the state's own guidance, including the generator ones, answered without a sales pitch.
Someone unlicensed did electrical work in my house. Can that be made legal?
It can, and this gets asked in South Jersey more than people admit. Getting legal means a licensed electrical contractor looking at what was actually done, which usually means opening up what was closed, then permitted work and a municipal inspection to close it out with a Certificate of Approval. Nobody here is going to make you feel stupid about it. The point of the call is the house, not the history.
The original question on RedditCan I do my own electrical work on my house in New Jersey?
On your own home, the state's licensing act has an exemption for work you do on a dwelling you live in yourself or that an immediate family member lives in. What that exemption is not is an exemption from permits and inspections, which apply no matter who does the work. It also does not stretch to a rental, a duplex or a multi family building, which is where most of the confusion comes from, and those need a licensed electrical contractor.
