Can I install a subpanel myself, or do I need a licensed electrician?

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

How long does a subpanel installation take to complete?

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Will adding a subpanel reduce my electrical bills?

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

How do I know what size subpanel I need for my home?

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

What is the difference between a main panel and a subpanel?

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

Does installing a subpanel increase home value?

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.

"He arrived when expected. Personable and easy to talk with. He understood our concerns as our house is 101 years old. Two 50 year old kitchen ceiling lights were replaced with efficient app-controllable LED fixtures. A failed GFCI receptacle was also replaced. In our music room he replaced a 3-bulb incandescent ceiling fixture with a 52” 5-blade remote controlled ceiling fan with triple light kit. It is completely silent. All projects were completed in very good time. He was very respectful of surrounding surfaces. All work was done neatly and with care. My wife and I were very happy with his way of working. He wasted no time but still double-checked all that he did. He made sure we had all necessary manufacturer info regarding app programming and use. We would gladly hire him again for all electrical work. We couldn’t be more satisfied by his estimate and how efficiently he worked. A total professional!"
