I just finished wiring my lights, 5 LED Fat Boy spots, and 1G4 Infinity 60 into the slim line 100 watt transformer. I used 2 of the Pro Macro Junction burial boxes as well. This led to 2 main wires coming into the transformer. when I plug everything in though the built in fuse in the one switch pops. I have no idea why. they only way i could get it to work was when I plugged in a single fat boy spot. Any help would be appreciated.
Hey Pryor, You are certainly within the recommended operating range load wise so, it sounds as though the transformer is tripping due to a connection point. It is essentially tripping to protect itself and the fixtures as it is designed to do. The source may be a loose wire connection, damaged cable, or a fixture. The best way to tell would be to double check all of your wire connections and cable, if those all check out, then I would recommend testing each of the fixtures directly at the transformer (like you did with the one fat boy). This process of elimination should lead you right to the culprit!
