50A GFCI-protected spa circuits with code-required disconnects — permitted and inspected.
A hot tub or spa circuit is a dedicated 240V run from your electrical panel out to the spa pad, with GFCI protection, a disconnect within sight of the tub, and bonding where the code calls for it. Fifty amps is the common size for a portable spa, but the number that matters is on the equipment nameplate. We read the plate and the manufacturer's instructions before we size a breaker or pull a wire.
The disconnect is the part homeowners are usually surprised by. Code requires a way to cut power to the spa that is readily reachable, within sight of the tub, and set back from the water by the required distance — so nobody has to reach across the water or walk back into the house to shut it off. On most jobs that is a weatherproof outdoor enclosure holding the GFCI breaker and serving as the disconnect in one box. It is not optional, and an inspector will look for it.
Bonding is the other piece. Metal near the spa that a wet person could touch gets tied together so everything sits at the same electrical potential. Self-contained portable spas that are listed for it already carry some of that inside the cabinet. Which parts still need bonding on your install depends on the unit and on the deck or pad it sits on, so we confirm it against the listing rather than guessing.
Two Santa Cruz County realities shape most of these jobs. First, panel capacity: a spa is a large 240V load, and plenty of county homes are still on a 100A service already carrying a range and a dryer. Run the Panel Load Calculator or have a tech check it in person — sometimes the honest answer is that the spa circuit waits behind a 200A service upgrade. Second, weather: a spa circuit lives outdoors year-round, and within a few blocks of the water the enclosures, fasteners, and fittings have to be chosen for salt air or they will not last.
A tech reads the spa nameplate, checks your panel for capacity and an open slot, and walks the route from the panel to the pad. You get a written scope and a real quote. If the service cannot carry the spa, you hear that here rather than after the trench is open.
We pull the electrical permit with the right authority — the County building department for most unincorporated addresses, the city only in Santa Cruz, Capitola, Scotts Valley, and Watsonville — and book the install around your delivery date.
Breaker into the panel, conduit or trench along the route, weatherproof disconnect set near the pad, terminations at the spa, and bonding completed. Power is off only while we are working inside the panel.
The inspector signs off the circuit, then we show you the disconnect, test the GFCI with you standing there, label the breaker, and hand over the permit number and sign-off with the invoice.
There is no flat price for a spa circuit, because almost none of the cost is the breaker. It is the run: how far the spa sits from the panel, and what the wire has to cross to get there — an open side yard, a trench under a paved path, a crawl space, or the underside of a deck. Two houses on the same street can land far apart on that alone. The second variable is your panel. If there is no room or no capacity, the honest quote includes that work, and the Panel Load Calculator will usually tell you which of those two conversations you are about to have. We look at all of it on site and give you the number in writing. Quotes are free either way.
“Sunrise Electrial in Santa Cruz came to my home in a timely manor, and reasonable cost to replace a sparking switch plate. This is a relatvely young company, with a very pleasant and knowledgeable owner. He explained everything he did. Please consider Sunrise Electric for your electrical needs.”
“Sunrise electric and especially Ian was amazing. They had already came out with less than 1 days notice and replace our panel, but then outlets and lights were not working. Called them to inquire and they quickly sent Ian to our home. Within 30 minutes he repaired the issue. Excellent customer service and knowledge about the issue. Timely and super nice too. Ian put me at ease immediately and left me with all working electrical!!! I am extremely happy with Sunrise Electric. 🌅. Cecelia N”
“They did an excellent job in changing a circuit for me and also fixing some light switches. The person that came out was very knowledgeable worked quickly was very professional and polite. They let you know when they're on their way. They confirm the Appointment And it was a great experience I would use them again and I highly recommend”
Pulled from what we actually hear on quotes and on-site. If yours isn't here, ask us — we'll answer in plain English.
We'd rather you get the right outcome than the Sunrise outcome. Some of this points away from us on purpose.
Look for a CSLB-licensed C-10 contractor near you and verify the number at cslb.ca.gov. Ask for liability and workers-comp proof, and ask whether the quote includes the permit, the disconnect, and the bonding — those are the three line items worth confirming in writing.
