On a 230v motor install my wiring diagram shows Line 1 as the top post and Line 2 as the bottom post. What color wires are typically associated with which or is there a way to tell what wire should be my line 1 vs line 2? This is a pentair whisperflo.

basically either or as long as you follow the diagram on the side of motor it does not matter when hooking it up to the timer.

I have seen black-black, white-black, red-black & all have been different.

On a 230 line typically you will have two current carrying wires and a ground. The "hot" wires are normally black or red. Like MrClean said, doesn't matter which hot wire goes to line 1 or line 2. The ground wire should be green and connect to the ground screw.

Ok I was confused because I didn't look at my clock diagram first. There it clearly labels the L1 and L2 posts. Thanks!

I replaced my pentair booster pump over the weekend. The shaft is turning counterclockwise, when facing the pump intake. According to pentair this is backward, what did I do wrong?

I think I have the same 2HP pump and was wondering where the neutral wire is supposed to go?

After thinking about it some more, can someone please confirm that I'm supposed to use 14-2 wire enclosed in metal conduit, run both the black and white wires to my HOT leads from the timer relay and then the bare ground goes to green. Then there really is no neutral in this diagram?

According to the electrical requirements diagram, I can use 14 AWG for 230V on 2HP less than 50'.

Hi,

What voltage is your time clock? Normally you would have 2 hot wires coming to the clock (black or red) and then you run 2 hot wires and ground to the pump motor.

I like to use sealtite flex conduit to run from the clock to the pump motor.

Thanks for your feedback Denali.

I'm using a "Fiberstars WPC-2" Wireless Pool Control Unit with a timer that can be wired for either 110V or 220V with a max load of [email protected] continuous load.

I'm extremely disappointed with the so called "Technical Support" for Pentair. They refused to discuss anything about the wiring to the pump and wouldn't even confirm that there is no neutral wire to be installed on the pump.

I'll definitely buy the pvc flex line since that sounds like it's a lot easier to work with and use some 14-2 romex that I have left over from wiring my shed.

Thanks Again!

Okay now I seem to have confused myself some more. I was originally thinking that I've got a single speed pump, but after looking at the wiring diagram on the side of the housing, it's making me think that it's a dual speed pump:

I say this only because it lists a LOW VOLTAGE and a HIGH VOLTAGE, but if it's a dual speed pump, then the wiring diagram for the WPC-2 shows 4 inputs to the pump and there is only room for 3 inputs.... :crazy:
