What size circuit does a hot tub need?

Most residential spas: 50A 240V. Larger spas with heaters, pumps, and lights: 60A. Small plug-and-play spas can run on a 20A 120V circuit.

How much does hot tub electrical installation cost?

Typical install: $900–$2,500 depending on distance from panel, trenching requirements, and disconnect box.

How far from the tub does the disconnect need to be?

Within sight of the tub, but at least 5 feet away and no more than 50 feet — per NEC 680.12.

Do I need a GFCI for my hot tub?

Yes, always. Required by code and by every spa manufacturer's warranty.

Can the circuit run overhead or does it need to be buried?

Both allowed. Buried is more common — 18" deep in conduit or 24" deep direct-burial.

How long does it take to install a hot tub circuit?

One day for most installs including trenching, disconnect, and inspection.

Does my panel have capacity for a hot tub?

We run a load calc during the estimate. Many homes need panel space or capacity added first — we quote both if needed.

Can you coordinate with my hot tub delivery?

Yes — we schedule electrical rough-in before delivery and final connection after tub placement.

Do I need a permit for hot tub electrical?

Yes in every DMV jurisdiction. We handle permit and inspection.

Can I install my own hot tub electrical to save money?

It's usually illegal for homeowners because of GFCI, bonding, and grounding requirements, and it voids most spa warranties. Not a DIY project.
