PX300 Transformer wiring Question..

[PoolWayne]

J,

What about the diagram do you not understand???

The 120 volts comes in on the left side of the diagram..
The black hot input wire gets connected to the black wire coming out of the same side of the transformer as the Blue and Yellow wires. Cap off the Blue and Yellow wires.
The copper wire goes to the ground lug
The White neutral wire go to the opposite of the transformer where the two black wires come out..

The two black wires go to the light.

To be honest, that is a dirt simple diagram.. If you don't understand it, then I suggest that you get a friend, or electrician, with some basic understanding of electricity to help you. Better safe than sorry...

Thanks,

Jim R.

This is confusing, as the diagram that you posted does not appear to match the instructions that are included with the unit on the sticker on the inside of the panel?

Or maybe I'm interpreting the label incorrectly, does it say "black to 120v" *and* "White to Neutral". I think so. Confusing.
I read it as "black to 120v/white" -> Neutral.

Correct.

Black hot 120V wire from CB connects to black, yellow or blue.

White neutral from CB or panel connects to transformer white.

Wayne,

With normal house wiring, Black is the hot lead, White is the neutral lead, and ground is ground..

In this case, you are connecting to a 120 volt transformer that is going to change the voltage to low voltage AC..

You connect the incoming Black wire, that has 120 VAC, to the Black, or Yellow, or Blue transformer wire, depending on what voltage you want out of the transformer..

If you want 12 VAC out of the transformer you connect the incoming 120 volts to the Black transformer wire
If you want 13 VAC out of the transformer you connect the incoming 120 volts to the Yellow transformer wire
If you want 14 VAC out of the transformer you connect the incoming 120 volts to the Blue transformer wire

The white input wire still goes to the white transformer wire

And the Ground still goes to the ground lug.

All the low voltage output wires are in the lower right section of the enclosure

All the high voltage input wires are in the lower left section of the enclosure

Please let us know if you have any questions.

Thanks,

Jim R.

@JamesW

I did not count the words in my response above, but clearly your picture is worth more than all my words...

Thanks,

hi guys can anyone can explain me how to wire the px300 transformer thanks

That diagram is great...but also worth pointing out a few gotchas:

1) The Intermatic transformers have the 120V inputs on the left side, and the low voltage outputs on the right (opposite of the diagram)

2) The output wires are larger gauge/thicker than the input wires (different than the diagram implies). This makes sense electrically, because the current is higher at 12V for a given wattage and wires are sized to the current...but can also be counterintuitive just glancing at it. A certain person with an electrical engineering degree wired one backwards a few years ago, and I...I mean a certain person...got to buy a new LED bulb after supplying 1200V to it
