What Size Breaker For Hot Tub?

Why Breaker Size Is Important?
You must listen that a 50 amp breaker is suitable for almost every hot tub.
As most of the house owners use 50 amp circuit breakers this becomes a rumor. But the fact is all the hot tubs don’t need a 50 amp breaker.
You will be surprised to know if you use a 50 amps breaker where the hot tub needs 40 amps breaker can create disaster.

The starting amps that are required for a hot tub are not the same as the required breaker size.
Suppose your hot tub specifications mention that the starting power is 40 amps.
It does not mean the breaker needs to be 40 amps. Check what the manufacturer recommends for the circuit breaker.
In most cases, the brand suggests using a 50 amp circuit breaker.
Suppose the starting amp is 48-50 then the recommended size will be 60 amps.
This difference is common for hot tubs because manufacturers consider other features of the hot tub.
