I am installing a replacement Intermatic T104P201 Pool Timer and have two set of red and white wires. I have rewired exactly as I thought it was befire and all that happens is the circuit breaker trips. Can I assume per the answer below to a similar question that the white is the same as the blacks.

Any other reasons it may be tripping? Other options to explore?

Thx!

"This switch is a "double-pole, single throw" switch, meaning that it opens and closes both hot wires simultaneously. Connect the black wire from the breaker panel to terminal 1 (line) and the black wire from your pool pump to terminal 2 (load). Connect the red wire from your breaker panel to terminal 3 (line) and the red wire from your pool pump to terminal 4 (load). Having said this, I would double-check the ratings plate on your pump motor to be sure it is 240 volts. It should be fed from a common-trip circuit breaker that disconnects both sides of the line when it is turned off."

Without using a voltage tester to determine the purpose of the red and white wires,


Can I assume per the answer below to a similar question that the white is the same as the blacks.

Any conclusion will be an assumption, and guessing how to connect it.

Do you KNOW which wires are the feed from the panel, and if the voltage is 120 or 240 volts?

Sounds like you connected it properly, but without testing the wires, who knows.
