This kind of falls in the “if you have to ask” territory.

While it’s technically pretty simple (you’re just moving it, not setting it up initially), code has specific rules, and this is the knowledge you’re paying for with an electrician. Since code can vary, knowing the code for your area may be important.

May be worth a call to the electrician about the code and homeowners doing such work. He may not mind talking about it. Just be honest with him.
