Hey Joe,

Thanks for your response. The TX in question might have been 13.8 volts or something unloaded, I was just rounding it off to 12 for illustration purposes.

RODALCO, thanks too. It just seems like if the NEC tells us that, for example, 12 gauge wire is for 20 amp circuits, something should tell us the amp rating of an unmarked transformer, going by the wire thickness. How will a transformer fail anyway? I don't know, but would assume that it would be the wire burning in half and/or shorting out due to over-amping. JWhite? Any opinions or advice from the master?
