For part number 750-30-0004 Brushless Control is factory set current limit to 20 amps.
You should not have to change this setting.
You can set the current limit to a lower value by turning the current limit trimpot counter clockwise. This will lower the current.
The current limit is adjustable from 0-200%. When it is facing forward, it is set at 100% or 20 amps. Rotating the trimpot 90 degrees counter clockwise will set it to 10 amps.
Rotating it clockwise from that position 180 degrees, the control will be set at 30 amps current limit.
The overload current is 200% for up to 30 seconds before the control will automatically cut out.
