I Just received my Toroid from Apex today and I am confused by the wiring color coding. Can someone please help?

6 Primary (I believe as there are short wires)
- Black
- Blue
- White
- Gray
- Purple &
- Red

8 Secondary
- Yellow (solid & Stripe)
- Orange (solid & Stripe)
- Black (solid & Stripe)
- Red (solid & stripe)

From Grey's posting above, I already found out the Secondaries--
2x Yellow to bridge
2x Orange to ground
2x Red to ground
2x Black to bridge

BUT, how do I wire the primaries? Thank you for your help.

The 1010VA's only have 2 primary windings. What transformer did you buy? I don't see any white or red primary leads here.

If you indeed got the 1010VA from ToroidTech, you wire them for 110V/120V in parallel as Grey did, or 220V/230V/240V in serial as I did.

If you are confused, the thick wires are the secondaries and the thinner are the primarys.

Ok, Just checked the Toroid I got. The part number is TC50008, VA 1010P/P, Input 2x100-120VAC @ 50/60Hz. I do not see any brown wire but have 3 extra leads, black, white and red (pink?) Please help. Thank you.

My three transformers have all written TR50012 on them. If yours are different from mine, I cannot give the colours to you.

As you wrote, the transformer has 2x primarys. This means you should have four leads for the pri.windings. The four leads should be thinner then the secondary taps. If you only have 3 "thinner" leads, this could mean one of them is common for both pri.windings. You also mentioned 6 primary leads, so maby you have 2 "sets" of them. You realy should try a ohm-meter to find out your self.
