Service Upgrades provide the home or business with the potential to consume higher amounts of current and wattage. This is likely to be the case, when there is an addition of appliances, rooms, kitchens, shops, garages, and living space. Service upgrades have jumped from 60 ampere services to 200 amp services. Petersburg, Richmond, and Colonial Heights Virginia, are known for having historical homes in existance, and because of that-almost all residential homes have needed a service upgrade in the last 50 years.
