Electricity use has increased at a rate of about 5% per year for the past 30 years, and each new year puts additional demands on an old home’s wiring. Also, the lack of wall receptacles in an older home, due to the low level of use of the era, contributes to the problem. But sometimes an older home grows with additions over the years to 2,000 square feet or more, with air conditioning, electric clothes dryer, range, and dishwasher. The original panel is undersize in both electrical capacity and space inside the box to fit all the wiring.
