I'm in the process of rewiring my layout. I'm using a MRC pure power dual transformer with Legacy, TMCC and DCS command control. The layout is 16 ft long and 4 ft wide. I found a bus bar on Amazon that has 8 outputs  (of course I'd need two for multiple loops of track) would this work?  https://www.amazon.com/gp/aw/d...FPW259YSFR&psc=1

That would work, You have about 40' of track per loop. 4 power drops (one every 10') would be enough most likely so you could shop for a smaller terminal block if desired.

If you're running Legacy and DCS engines (expensive) I'd see about adding some railings of some sort around the layout so one of your trains doesn't take a header into the concrete floor.

Mark

Thank you. Yes, I should put a railing on the edge.

I use just terminal strips and make however many of them common with the shorting strips (just cut off as many as you want terminals connected together). And this way you can use heavier feed wires (the ones shown in your link are a bit light).

I'll just use those, they look to be better than the one I was looking at. Would 16 gauge wire work well or should I go with 14? 

I'd use 14 for any longish length of wire run. Maybe 16 or 18 for a foot length. By the way, much of the red/black "speaker" wire you find on line is copper clad aluminum. It has a lower amperage per foot rating by about one gauge step. Sometimes it's hard to tell what they are selling, but just use a generous gauge like 14, and it'll be fine.

I wouldn't chance it. Most of those have very thin wire connecting the terminals; certainly not big enough for track power. I have a couple, but only used for Fastrack switch power and some leds in houses. Get a regular terminal strip and use jumper bars to make it a bus bar.

Would they be good for accessory power? I'd use 22 gauge wire there at 14v. I'm going to use the one that Cjack showed me for my track power.

It depends on the accessory. For some it would be fine others, not so great, still others; a meltdown.

  If wiring gets hot, it's too small. If motors get hot, wires just warm, it might be too small. It may take a bit too as its a rising thermal build up that you watch for more than just a warmth. It may take 5 seconds or an hour...?

Most of my accessories are just lighted buildings nothing fancy. I only have one operating accessory a mth transfer dock. Which I will eventually convert to ERR. I also have a MTH passenger station that I will add smoke units to.

Would 10 gauge be overkill for my layout? @Ron045 or should I go with my original idea of 14 gauge.  

I guess it depends on if you are doing STAR wiring or a BUSS with feeders.  Alan Arnold told me about the BUSS method and recommended 12 gauge.  I went extra and did 10.

Ron

I was going to do buss with feeders. I'll go with the 10. 

That would be way over kill. Use 16 or 14 ga or wire that will fit into the connector crimp and run it less than 2 feet into a connector block. Then you can run 12 ga to the transformer. It’s important to use multiple feed wires along a particular loop than using a wire gauge that is difficult to handle or plug in under the track. Just make your smaller, easy to handle, wire under the track short to the connector block where you will go on to a heavier gauge.

Alright, I'll do that.

No. They have to say .110, .125 or 1/8 inch somewhere in the listing. That’s the width of the spade. I think the .110 are the closest to what Lionel uses. 

Do you have a terminal track with the wire that Lionel supplies with it. That’s the skinny spade you should use.

Yes, I do have a terminal track. Thanks. I'll get the first set you showed me. Thanks for the help.
