Quick Answer
An electrical capacity assessment helps homeowners think through whether their electrical system should be professionally evaluated before adding major loads — EV chargers, HVAC equipment, electric ranges, hot tubs, pools, additions, finished basements, or modernization projects. This tool provides a general screening recommendation only. A licensed electrician or qualified electrical professional should always perform an in-person evaluation with the appropriate tools before any final recommendation.
NEC note: Electrical installations and evaluations are guided by applicable code requirements, including the National Electrical Code (NEC), which is widely used as a benchmark for safe electrical design, installation, and inspection. This online assessment does not perform an NEC load calculation.
Not sure is okay. Confidence adjusts if key information is unknown. Your result is only as accurate as the information entered.
