N-68x isolation transformer wiring for s-38c

[N9axl]

Can someone please explain the wiring of this? For 115 VAC it says tie blk/red/blck Yel/blk-grn/blk apply to blk-yel/blk

I can't figure out which one of these is hot and which is neutral. same on the other side- both output leads are red.

I think I'm supposed to put these leads together but I'm confused.

With any power xfmr or isolation xfmr there is no one lead or terminal that is neutral.  You can connect either lead to neutral, other to the hot leg.  Same is true for the secondary.

You color description of the lead wires is not clear.  "tie blk/red/bick  (what is bick??)  What isolation xfmr do you have??  Make and model??

Maybe post a pic of the xfmr or a pic of the text you're reading from.

Thanks Pete, I looked for the xfmr type, thought I read it but didn't again see it.  Duh, it's in the title (N-68X)

Ok FB, he should be able to hook it up, but I'll post the correct wire connections.

For 115vac on the primary connect together leads   Blk and Red/Blk  then connect together leads  Yel/Blk and Grn/Blk

Connect one leg of the AC line to the  Blk and Red/Blk pair   the other leg of the AC line to the Yel/Blk and Grn/Blk pair.

Doesn't matter which pair is the neutral or hot leg.  Same is true for the secondary.

Thanks. That worked. Primary wired to the power cord, secondary wired to the on switch and the rectifier. It works well and I have infinite resistance between the power plug and the chassis which is the point.


 This means the primary side is hot all the time, but I will put an inline switch in the cord for that. Don't know if it matters, but anyway.

Now onto replacing all the caps and done.
