Wiring connections on a new 120v pool motor
I am putting a new pool motor on my pool pump. The motor has a dial to select between 115 and 220 volts. I have selected 115 because that is the suppy voltage.
My question is: Where to put the hot and where to put the neutral. The diagram just shows "line" coming off of L1 and L2.

I've gotten conflicting advice from different people. Some say polarity matters and some say it doesn't. I just talked to the company I bought it from and the guy said neutral needs to go on L2. When I asked him how he knew that, he said because he's wired a lot of them. Then he coughed twice and hung up on me.

By NEMA standard, low voltage (less than 600V) motors are actually rated at 115V, 230V or 460V with a +/- 10% acceptable tolerance. This accounts for the anticipated 5% branch circuit voltage drop from the nominal 120V, 240V or 480V supply voltages plus a normal variation in voltage coming from the grid.
