A little frustrating....should be easy

Is it the same locomotive that trips the breaker or is it caused by different locomotive ?

All 3 engines are on the same loop or oval ?   Each engine should draw about 2 amps or under. If you are running smoke figure a little under 4 for each one.

.1 amp doesn’t seem right. Is it one particular engine ?   Can you use any combination of 2 but just not add the 3rd engine into the equation.

Are you running them using the All Feature ?  Do they all start at the same time without issues just sitting there idling ?

I have 7 locomotives and it happens in all combinations. Thanks Glenn

I start them separately. I thought they should draw more than 0.0 to 0.1 amps. I even changed to my other Z4000. No difference. I’m at a loss. Glenn

PS. I’m not sure what the All Feature is. I put one on, run it, add the second, run it, add the third and the breaker pops. All on the same loop.

That rules out the locomotives so the next thing will be the Z4000.
