Hot Tub Wiring Replacement – Estero, FL

PROJECT DESCRIPTION: HOT TUB WIRING REPLACEMENT – ESTERO, FL

Coharbor Electric recently completed a hot tub wiring replacement for a homeowner in Estero, FL. The customer had an existing hot tub circuit that was originally wired with #8 conductors. Since the spa required a 50-amp load, the smaller wire size was not adequate or safe for long-term use. To ensure code compliance and protect the system from overheating, our team upgraded the entire run with properly rated wiring.

WHAT WE DID:

• Removed the existing #8 wire that had been running from the electrical panel to the hot tub disconnects.
• Installed (4) #6 THHN wires, fully rated for 50-amp capacity.
• Properly terminated all connections at the main panel and disconnects.
• Wired the hot tub directly into the circuit, eliminating the outdated plug-style setup.
• Tested amperage, grounding, and continuity to confirm a safe installation.
• Cleaned up the workspace and confirmed proper hot tub function after the upgrade.

THE RESULT:

The spa is now powered by a safe, hardwired 50-amp circuit with conductors sized correctly for the load. The direct connection not only improves reliability but also eliminates risks associated with undersized wiring or plug-style connections. The homeowner can now enjoy their hot tub knowing it is wired safely and up to NEC standards.

FREQUENTLY ASKED QUESTIONS

Why was the wiring changed?
The hot tub required a 50-amp circuit. The existing #8 wire was undersized and could have caused overheating. We replaced it with #6 THHN conductors to handle the load safely.

Do hot tubs always need to be hardwired?
Most modern hot tubs require a dedicated hardwired circuit. Plug-in connections are less common and not ideal for high-load systems.

How long did this project take?
The replacement took only a few hours, including removal, installation, and testing.

Do you service other outdoor electrical systems?
Yes—we handle pool and spa circuits, dock and boat lift wiring, and other outdoor electrical projects in Estero and surrounding areas.
