hbporter Posted December 7, 2019 Share Posted December 7, 2019 When running 2 Lionel GP-9's on the same track(double headed) with a MRC 6200 transformer, the breaker trips after about 5 mins? Do I need a larger transformer? Any advice would be appreciated. Quote Link to comment Share on other sites More sharing options...
Chuck Posted December 7, 2019 Share Posted December 7, 2019 Yeah those don't have much power. From what I found online specs are 0 - 18.5V DC @ 35VA which is only like 1.89 amps....barely enough for 1 GP-9. Here's a review I found on Amazon... "This power supply is great for any modeler in HO, but it has limitations in "G" scale. It simply doesn't have enough power to run anything larger than a single motor locomotive. If you try and run a double header, or a locomotive with twin motors, the unit gives it a try, but after about ten minutes the circuit breaker trips and you're out of action for about fifteen while everything cools down."
