Set this as low as possible without getting OC faults in normal use to maximally protect your equipment. If larger than ''Medium'' setting is needed, see [[Over current fault troubleshooting]] for solution to the problem. | Set this as low as possible without getting OC faults in normal use to maximally protect your equipment.
