The length of the wire between the DC/AC power supply (P514) to the Booster/Command Station input is not critical. Just use heavy gauge wires like 14AWG or better. Nothing special otherwise needs to b

A twisted cable is defined as pair of wires twisted together with each other AND carrying the same signal/power/current going out and back. Twisting random wires together that have nothing to do with

This topic seems to have derailed into a layout question as opposed to YOUR decoder question. Almost ALL decoders made past and present support both DC and DCC mode of operation. The question is not i

This will not work under all conditions. Any Engine or any car with multiple wheel electrical pickup will still short the two rails together as long as the TRUCK, not just a wheel spans over the gap (

So that is a 2.6ft x 5.8ft or simply about a 3 x 6 layout. This sounds to small for what you want to do as described below. Do you mean a 32 feet x 70 feet by chance? So that works out to be two train

What scale are you running? How many people (Engineers) will be running trains? This is not the same as how many trains you run. How many running engines per train? The room suggest one could use a NC

No. It should not matter. Frog juicers work by detecting short circuits at the track level. It happens when a metal flanged wheel bridges between rail connected to the frog and rail the feeds the frog

Yes. Buss wire = 2 wires, one for each rail. You will need to install insulated rail joiners (gaps) in both rail to electrically separate the two power districts from each other. If you have a loop of

End of each. Placing them close to the booster defeats the purpose of the snubber. The goal is to install them at the far end furthest tack bus wire wise away from the booster. What is the difference

Professional Soldering Iron used for professional electronics work will have a Earth Ground connection. The Tip will be earth grounded for ESD reasons. The voltage will be zero at the tip. You will no

No one is following the DCC standards in US. No one has changed the design of their boosters since they were designed and release well before the standard came out a long time later. Best Regards, Mar

Simple Answer: They are not designed to be mixed. There was no DCC standard covering booster compatibility when the standards were developed. Although there is a standard today, it is to little to lat

Inrush current has no numerical value because there are a lot of variables.. But in all cases, it will exceed the current draw of just about any booster made. The question is how long does it draw thi

On larger layout without a load, you will see the track voltage go up the further you get away from the DCC system or booster powering the track. The is voltage ringing (spike) on the DCC waveform cre

There is no theory about how an autoreverser works. If there is no technical analysis supporting how offset gaps are solving any problem, then wye would one want to go out of their way spending extra

Not sure what you mean best setup for UP big boy. DCC systems only send commands to the locomotive’s decoder. What determines the feature set of a locomotive is the DCC decoder installed in the locomo

Yes using a large enough gauge wire will satisfy fault protection. Doing a coin short circuit test will verify if a given section of track is wire sufficiently to allow fault protection. But the very
