Im confused as to what you were doing, or what you are trying to do.
Are you trying to run all 3 engines at the same time on the same 180 watt brick? If so, yeah that could trip the 10amp breaker in the brick.
Yes the VLBB draws a lot of power with all 3 smoke units on, but 2 180 watt bricks is more than enough for those 3 engines if your track is split into blocks.
