You should consider upgrading your electrical panel when it is outdated, damaged, out of space or too small for the electricity your home uses. Adding major loads, such as an EV charger, heat pump or new kitchen, is also a common reason.
Not every home needs an upgrade. The right decision depends on the panel’s condition and the home’s current and planned electrical load.
Capacity and Electrical Load
Every panel and electrical service has a rated capacity, measured in amps. Older homes often have smaller services, which were designed for fewer appliances than many homes use today.
Signs that a home may be outgrowing its panel include breakers that trip often, lights that dim when large appliances start and a need to avoid running certain appliances at the same time.
A load calculation is the best way to know whether the panel can handle your needs. An electrician looks at the home’s size and its major appliances, heating and cooling equipment and any planned additions.
Condition and Age of the Panel
Panel condition matters as much as size. Heat damage, scorch marks, corrosion, rust and burning smells are signs that a panel may need repair or replacement.
Some older panels have parts that are no longer made. Certain older brands have been the subject of safety concerns, and fuse boxes are still found in some homes. An electrician can evaluate these panels and explain your options.
A panel with no open breaker spaces, or one filled with tandem breakers, can make it hard to add circuits safely.
Planned Projects and New Equipment
Many upgrades happen because of new plans. Adding an EV charger, a heat pump, central air conditioning, a hot tub or a home addition can increase demand on the system.
Kitchen and basement remodels often add circuits. Planning the panel at the same time can help avoid problems later.
In some cases, other options can work. Load management devices, rearranging circuits or choosing equipment with lower demand may avoid an upgrade. A load calculation helps compare these options.
What the Upgrade Process Involves
A panel upgrade in Denver generally requires a permit and inspection. If the electrical service size is increased, coordination with the utility, usually Xcel Energy, is also needed.
Power to the home is shut off for part of the work. An electrician can explain the steps and timing for your home.
Do not try to replace or modify a panel yourself. Panel work involves parts that can remain energized and should only be done by a qualified electrician.
