has anyone ever attempted the following - and can anyone share results on performance??
——————————
z-500 + z-500 vs z-1000
(4a;50w) x2 vs (6a;100w)
——————————
z-750 + z-750 vs PH135 or Z4K throttle
(4a;75w) x2 vs (7.5a;135w) or (8a;165w)
——————————
I feel like combining two z-1000 bricks (12a;200w) or two PH135s (15a;270w) or two PH180s (20a;360w) is just a crazy bad idea. Serious welding territory.
Anyone tried combining matched pairs of these smaller MTH bricks? Any good results?
Thanks

Paralleling the PH bricks is pretty common. Lionel actually sells a two to one sets of wires for doing just that to use with a TPC

Thanks, I am aware of that, but that’s not what I am asking about. I am wondering if anyone has done this with the smaller bricks MTH makes and if the breakers worked fast / if it was an overall success.
Despite the Lionel paralleling being common, I don’t like the idea of exceeding an 8-10amp threshold under any circumstances.
Well, the breakers on the MTH bricks are actually pretty slow thermal breakers. Also, I have personally observed that the excellent PH180 circuit breaker sometimes gets confused when they're paralleled.
If you connect two Z-1000 bricks in parallel, I suggest a quality breaker on the combined output.
I run Z1000's in parallel on all 4 channels of my TIU and use a single inline fuse for each pair. The only problem I had was that some are wired opposite inside making them out of phase with each other. The breakers would kick as soon as you connect the barrel jacks together. I eventually found 8 that were all the same. I did not want to mess with cutting the barrel jacks off to achieve getting them phased alike.

Couldn’t you have just flopped the - and + red/black barrel adapter wires from the brick to the TIU ports??
DDOTCDOT, I use the pre-made "Y" type cords.
