I run SS and have feeders about every 20-30 feet, BUT I have all SS SJ clamps, AND all my wires are home run, AND all are 10 gauge. This is not overkill, I run trains with lots of locomotives and can use close to my 10 amp capacity.
I don’t believe Steve has overkill.
You need to look at all the variables… if you run just one loco, and DC track power, you will have minimal voltage drop, since you aren’t drawing a lot of amps. Also, when your speed drops because of your few feeders, it’s no big deal, you just turn the throttle up. So you CAN have just a couple of feeders.
On the other hand, if you run a system with constant track power, you notice more readily voltage drops, and drop in speed. Then run about 5 locos at a time on a railroad with 2 feeders, you will change your tune.
The point is that you need to know a bit more before you proclaim you are right and the other guy is wrong.
So, for some people Steve’s wiring is wrong/overkill. If I came over, it would be great!
Different strokes for different situations!
