How do I limit the power that my spa draws from pumps and blowers?

If the available power (amps) for a spa circuit is limited, the installer must consider how much current (amps) each jet pump and/or blower will use and where required must adjust the 1.LLM (load limit) setting to restrict the number of loads that operate at the one time, to keep the total power draw of the spa within the circuit breaker limits.
