circuit breakers provide overload and short circuit protection, combined with
Class A ground fault protection. Class A denotes a ground fault circuit interrupter that will
trip when a fault current to ground is 6 mA or more, for people protection. Do not connect
to more than 250 feet of load conductor for the total one-way run to prevent nuisance
tripping.
