Reply to "3-position reverse polarity switch for DC power lines to track?"

Adriatic,

Thanks for that fantastic diagram.

My "starting out" transformer is a Lionel 4150, in excellent shape. 50 Watts, 7.5 amps, secondary voltage of 8-15 volts. (Paid $12 for it.)

Four questions:

1. Is a 4.5 amp fuse considered "standard" for running DC trains? Or, do I need to do more research about amps?

2. What gauge of solid wire are you using in the picture?

3. What do you guys mount your rectifier and polarity switches on? I'm kinda nervous about mounting them on a plate of sheet metal, for fear of shock and shorts. On the other hand, is it "considered safe" to mount them on a piece of plywood, or does this create a fire danger?

4. Is this little transformer going to be able to run two DC engines, 027 size? Or just one?

Thanks for any answers.
