Most spas have a 50amp 2 pole main circuit breaker. A 60amp breaker is required by some spa manufacturers. Although some manufacturers state their spas can use 8 guage wiring for a 50amp circuit, we recommend 6 gauge wiring on the 50 amp circuit.
If your spa is located in a residential area, you may want to consider installing a circuit breaker in the basement or crawl space.

The temperature affects the copper conductor’s Conductivity. However, if the conductor is heated to more than 200° F (93° C), the copper will begin to lose its ability to conduct electricity. This is why copper wire is not recommended for use in high-temperature applications. Copper conducts electricity better at higher temperatures than at lower temperatures.
The reason for this is that copper is more conductive at high temperatures because it has a higher melting point. As a result, copper conducts more electricity when it is hot, and less electricity as it cools down. Copper is also more resistant to corrosion than other metals, which makes it a good choice for applications that require long service life.
