Wiring new B852 Century motor 115v.

[Thinkly]

I am putting a new motor on my Pentair Challenger pump. The pump will be wired 120 volts. My question is, where to put the hot and where to put the neutral?

The motor has a dial which I turned to select 115 volts, so I know that is OK. However the connections just say L1 and L2. The diagram just shows "line" coming off of L1 and "line" coming off of L2.

Wow that diagram and pretty worthless. I found some other pictures that show that the incoming wires go to the same terminals, but the wires in the motor are changed, maybe that dial is changing things internally?

I think I would put your neutral on L2 and the hot on L1 based on a different Century drawing I found.

Jason got it. as he said, not the best diagram. Black on L1 and white on L2. The switch sets the voltage internally.

That's what the guy at Swimming Pool Supplies, Pool Safety Cover, Swimming Pool Covers, Swimming Pool Pumps, Pool Pump Parts - INYOPools.com
told me to do as well. Strange that the diagram doesn't specify. Makes me wonder if it matters?

Black to L1, neutral to L2.

Just as a side point, I work in an industry building fans. Many single phase motors don't matter which terminal you connect line and neutral. Lots of 1 phase motors have additional motor leads that you adjust to cause clockwise or counterclockwise shaft rotation and 115/230V.

Yours looks to be quite simple. Set dial to 115V, black to L1, white to L2.

It should work either way. If it mattered, the diagram would specify.
