It is a dual primary transformer. I labeled the pins 1-4 . Pins 1&3 are one primary winding and pins 2 & 4 are the other.
First confirm that there is a DC resistance between 1&3 and 2&4 and that there is no connection between the even and odd numbered pins.
For 115V operation connect 1&2 and connect 3&4
For 230V operation apply voltage to 1&4 and jumper 2&3
Thanks so much!! So 1 and 4 both get the hot side and 2 and 3 both get neutral, correct?
Out of curiosity, is that center marking a standard sign for neutral? I haven't seen that before?
I didn't ever say to do that.... I guess the next thing I should say is get an ammeter, variac and a fuse since the hookup you described mayl draw a lot of current and cause some sort of failure.
You haven't stated what voltage you are trying to wire it for so I will say it again.
first confirm continuity of the wires and that 1&3 are a pair and 2&4 the other.
For 115V operation connect 1&2 for hot and connect 3&4 for neutral
for 230V operation 1 is 0V 3 gets connected to 2 and insulated and 4 is 230V/
The marking in the center isn't a symbol. It's just showing how the wires from terminals 2-3 connect to their respective windings.
Buy Chinese. Bury freedom.
