I bought a 12v transformer from Radio Shack for my Powder Coater
project. It has two wires for the 120v input but three wires on the
output side of the transformer.

I show 6.3v on each of the "hot" wires on the output side. Do I just
twist the two wires together to get my 12V? Is this done to get more
AMPS out of a thinner wire winding?

I just know y'all have the answers I'm looking for.

Thanks


If it has three wires on the output side, one (typically the one that
is a different color) is a center-tap. You ignore that (put tape or a
wire nut on it) and use the other two for your 12V. If you connect any
of those three wires directly to any another the transformer will show
its extreme displeasure by getting very hot, smoking etc.
