Can your panel handle what you're adding?
An EV charger, a heat pump and a hot tub are each fine on their own. Together they're a different story. Answer a few questions and see roughly how much of your electrical service is already in use.
Panel Capacity Check
A simplified NEC 220.82 load calculation. Free, instant, no email needed.
This is an estimate, not a quote or a permit document. It applies the optional calculation method in NEC 220.82 using typical appliance values, and doesn't account for your actual equipment ratings, breaker spaces, conductor sizing or your city's requirements. A permit-ready load calculation needs an on-site visit by a licensed electrician. JP Electrical Solutions Inc., CSLB #1092719.
Under 70%
You have real headroom. Adding a circuit is usually straightforward, as long as your panel has breaker spaces free.
70 to 90%
Workable, but tight. Worth pricing an upgrade, or a load management device, before you add anything else.
Over 90%
You're at or past what the service is rated for. An upgrade or load management is almost certainly needed.
