Determining whether a service upgrade is necessary depends on several factors, including the age of your electrical system, the capacity of your current panel, and your increasing electrical demands. Some common signs that indicate a service upgrade may be needed include frequently tripping circuit breakers, inadequate power supply for appliances or equipment, flickering lights, or the addition of a home addition or renovation project. It is recommended to consult with a licensed electrician who can assess your electrical system, evaluate your power requirements, and advise if a service upgrade is necessary to ensure a safe and efficient electrical system for your property.
