Added Powermaster and common wire got hot!

What size is the wire???

HOT equals trouble, excessive current draw. My powermasters are sitting in the box under my layout.

I run with a TPC-400 and 2 180 power bricks with the twisted powerr cords for no problems for TMCC, no LEGACY yet, too many problems for my taste.

Remember these are just my opinions.

Also, seems to me I remember my dealer friend (who reads these posts) telling me some of the powermasters were wired wrong from the factory, I know some of the 180 bricks were. You should check.

Is this the ONLY transformer connected to the track? Sounds like you have another transformer connection to the track, the PowerMaster output should be the ONLY thing feeding that track segment with power.

Gunrunnerjohn has it right transformer to powermaster and powermaster output to the track. I have my entire layout (in the early building stage) off one powermaster and it never gets hot even when running a train. I have 120 ft of operational track at present and I'm feeding all four of my blocks through it.

I am assuming when you say common wire you are talking about the wire from the PM to the track?

If so, what gauge wire is it? Same as your hot?

The PM adapter cord should have the fuse line on your A/B/C/D terminal and the non-fuse line on a U terminal. Then plug it in the PM.

Then I would check the two wires from the PM to the track. Good solid connectors on the wire, with a good connection to the PM and the track.

Then as others have stated ensure no other transformer is feeding the PM block. If so and that voltage is higher than the PM voltage, the PM becomes a load vice a power source. G

We tried it again, basically starting from scratch last night and all seems to be working. I can't explain it...maybe something was corrected when we re-did things. Who knows? I told my brother to keep an extra close eye on things - just in case!

Thanks for all the tips and help!
