I have an old Wadsworth panel (circa 1964) in our house. I recently got a quote from an electrician to upgrade the panel to Square D circuit breakers. He proposed to leave the old Wadsworth box in place, including the wiring entering the box, removing the existing circuit breakers and bus bars as well as the main fuses, and installing the Square D bus bars, main circuit breakers and new circuit breakers. This would result in less labor to remove the old box and rerunning the wires in the new box. Total cost would be about $600 (parts and labor) to approximately 30 breakers in a 200 Amp service. Does this sound like a reasonable approach?
Thank you.
