What wire gauge size for 1.85HP Hayward pump

[Drb1]

I have a Hayward SP3210X15XE 1.85HP pump and need to know what gauge wire I should use. I am making a whip for it running @ 230. I think I read that 230 can have smaller wire size than 115.
So is 14/2 good for 230v? Also just in case I ran as 115v should I then use 12/2?

Thanks for any and all help.

The manual says 14 is OK for 230, 12 for 115. Ground must be 12ga or larger, regardless. You are always better off with all 12ga wire.

Depends on the amperage of your GFCI CB you are using.

12 gauge wire for a 20 Amp CB

14 gauge wire for a 15 amp CB

Wire can be larger (lower gauge number) for a CB and never smaller.

I would always recommend using 12 gauge so you can change a breaker from 15 to 20 amps if necessary.

Thanks;
Box has [2] 20amp and [1] 50amp. The 20's must be [1] for each pump and the 50 is for the heat pump.

I have enough 10ga4-wire for a whip but I don't want to use it cause it is so thick and hard to work with

Picture?

With the 20 amp breakers minimum wire size is 12 gauge.

50 amp breaker wire size is 6 gauge copper.

This is what I used on the pump I am now replacing. It was very difficult to wire because of the size.

With stranded wire it is best to use crimp-on female spade connectors. Get some for that size wire and you'll be good.

Please check the mfg spec & installation sheets for your pump. They should have a chart. Length of the run has to be accounted for along with voltage and amperage. Excessive voltage drop will cause problems you do not need.

Just noting that you do not have GFCI CBs for the pumps that current NEC requires.

I assume that all three of the CB's need to be GFCI? I guess the money I saved on doing the pump myself will now have to spent on GFCI.

Heat pump does not require a GFCI CB. Gas heaters do.

Check the Heat Pump installation Manual.

Thanks everyone for the help. Pump is installed and working perfectly.
