Roger on that. It's hard to see in the photo, but bottom center is the end of a green wire with a yellow terminal on it. That will be connected to the female ground via another wire. Is there any reason why I shouldn't ground the housing of the transformer, or is that totally unnecessary?

Vinnie, I think that a much safer female for the secondary side would be one as illustrated below. You don't need to ground the transformer but put the whole thing in a box or behind a panel with the female connector protruding on a 16 Gauge extension cord cable that has all three wires in a rubber sheath.

  Roger on that. That has been the plan all along. Just trying to get the hookup order correct before putting it in an enclosure. Thanks.

"The drawing assumes there is some metal box housing the transformer. For safety that metal box should be grounded."
Vinnie you need to pay attention. Also that Rube Goldburg you have needs to be cleaned up.

  Uncle Mike, you need to read my posts before you reply to them. I said I was planning on putting it in a case when I had the wiring right. If I build a wooden case grounding the transformer might be a good idea, that's why I asked. As for the Rube Goldberg part, don't be so quick to jump to conclusions. That is the way I found it at the hamfest. I never said I was planning on leaving it that way.

    You are right, always right, do lovely work and everything you do is spot on correct.
    Myself I would be ashamed to post a picture of that kind of work no matter what stage but I'm not the expert you are.

      What part of "this is the way I found it at the hamfest" did you not understand? I haven't DONE any work yet.
