I am looking at an old Lionel 250 Watt ZW transformer that needs a little work. While I am in there, I am looking at replacing the rollers, circuit breaker, whistle diode, AND THE WIRING. My question is this: Can I use the typical, coated, solid #12 AWG wiring to replace the old cloth-coated wiring in the transformer? It (#12 AWG) may be overkill, but it is what I have, and if it will work, then I am OK using it provided it is safe and appropriate to use. The current wiring is solid-core, cloth-coated wiring.
As an aside, can stranded be used in place of the solid core? I have #14 AWG stranded on hand, as well.
Thanks for the advice/help,
