Key Safety & Code Points
- Permit & inspection: Required for most spa/hot tub installs.
- GFCI protection: Properly sized GFCI breaker or listed spa pack.
- Disconnect: Within sight of the tub and at required clearance.
- Bonding/equipotential: Bond metal parts and follow manufacturer specs.
- Clearances: Maintain required distances from outlets, lights, and windows.
- Wiring method: Wet-location rated materials; correct conduit/cable routing.
Power & Placement
- Nameplate first: We size conductors and overcurrent protection to the tub’s rating.
- Location planning: Pathways, barriers, and lid lift space considered before wiring.
- Outdoor runs: Proper burial depth/marking where trenching applies.
FAQ
120V plug-in or 240V hardwire?
Many tubs can run either way. 240V typically heats faster and supports full-function operation while jets run; we match wiring to the manufacturer’s requirements.
How long does installation take?
Typical hardwired installs take about a day depending on distance to panel, routing, and trenching needs.
Can I use an existing circuit?
Only if it’s sized and dedicated per the tub’s nameplate. Most 240V tubs require a new dedicated circuit and GFCI protection.
Do you coordinate inspections?
Yes. We pull the permit when required and meet the inspector to close out the job.
