Product FAQs
7 answersCan the JJL36250 be reverse-fed?
Yes, standard unit-mount PowerPacT J-Frame thermal-magnetic circuit breakers like the JJL36250 are suitable for reverse connection.
Is the trip unit on the JJL36250 adjustable?
While the thermal trip setting is fixed, the magnetic trip is adjustable. For this 250A unit, the magnetic settings feature a hold current of 1250A and a guaranteed trip current of 2500A.
What is the correct tightening torque for the standard lugs on this breaker?
The standard AL250JD lugs require approximately 225 lb-in (25 N.m) of torque. Always verify with the torque specifications printed on the device label and use a 5/16-inch hex bit to properly secure the conductors.
