Hi everyone I'm having a little trouble with my wire's voltage. I am using 26 awg wires for the 0.19 mm2 from Marklin and 24 awg for the larger one. Is this correct? Thewolf |

Yes, I think it shuld be sufficient. I used some 24 awg because it came in a longer spool and was available. Marklin says you only need 28 awg I think. Their wires supplied with the Cs3 look like 20 or 22 awg. becaue it has a larger digital booster, and they send all the data to the tracks. The C track wired terminal connectors look like 26. The wires from the MS2 track box, and former M track turnouts and signals look like 28 or 30. Thicker is no problem, and better for long runs. All of the screw terminals on M83, M84, etc. accomadate 24 awg.

I am not sure what you mean by "a little trouble with my wire's voltage." The weird Marklin transformer produces a combination ac/dc current and the real voltage is a combination of the two. You need a special multimeter that can read the combination to get the accurate voltage. At least that is what I sort of understand though it is all Greek to me. I just stopped worrying about voltage and amperage and just made sure I had continuity. That was hard enough at times.

This is incorrect. Please read the "Wiring Basics" chapter of the Large Manual, Märklin No. 03093. 18 awg (0.75 m^2) is recommended for both the main track and accessory buses. Feeds to the track from the main bus can be short lengths of lighter gauge wire. |

I think that in awg, the 0.19 mm2 does not exist, you have to fall back on awg 24 or 26 and awg 18 for the 0.75 mm2 Thewolf |

I use 0,75 mm square main connect and shortest way to connect the track from the main are 0,25 mm-0,34 mm square. This should be enough since we are writing about power feeder 60041 which do have 3 amps output. For bigger trains like scale 0 and 1 needs thicker wires because of the power feeder 60101 which does have 5 amps output. There is also two difference type of the wires...standard copper and tinned. Tinned wires are more expensive and are use in the industry for greater requirements. |

I wasn't meaning the wiring between the CS3 and track! I was only stating the comparisons. I have no problems with any M83's or turnouts with 24 awg. wire. These run fromtrack power to the decoders, which is only 1 metre at most. Wiring from the M83's to turnouts is very long. Events and throws fire right off unless delayed. I also used 24 awg from the contact tracks to the S-88 feedback.

My take on digital wiring: 24-22 gauge from decoder to switch, signal etc (short runs); 22-20 from decoder to CS (long runs) and 20-18 from CS to track power connects. (NB I have all M track and vintage accessories) |

Hi gang My voltage problem is solved. I'm like Einstein: the king of distraction and the older I get, the worse it gets. And as we say in Quebec: caliiiiisssssssssse !!! Behind the cs3, I connected the main path to the output of the programming path and the pogramming path to the output of the main path Merry Christmas to all Thewolf |
