A: Temperature can be monitored on any bolted connection within your power system. The probe is connected to any normal ring or spade lug connector with a 6 gauge barrel diameter. We include 1/2” ring lugs with the unit and we have 1/4" and 3/8” available. The screw/bolt is passed through a washer first and the lug second when installing on equipment. Once properly tightened as normal, the probe can be fixed to the ring lug. This is done by inserting it through the throat and tightening the set screw. DO NOT CRIMP THE CONNECTION.
