electric meter move advice
Things vary according to location but around here, you contact the local power company and request a temporary pole and disconnection of your current service.
Once that is done, you can complete your demolition and remodeling but the power company is going to expect to find a finished meter box that they can run the service drop lines to and then install and seal a meter for your new installation.  Then they will remove the temporary pole.
You are not authorized to mess with the always energized service drop wires on the company's side of the meter.
