Questions about this item

How do I decide between the 3 HP single-speed and 2-speed versions of the 56-frame pump?

The listed model is the 2-speed Executive 56-frame pump; the second speed lets you run filtration at lower flow and switch to high speed for jets.

What does the 160 GPM flow rate mean once the pump is plumbed into my spa?

160 gallons per minute is the open-flow maximum; actual flow will be lower after plumbing, fittings and head loss in your specific installation.

What does the 230 V rating cap in practice for wiring and breaker sizing?

The motor runs on 230 V single-phase power; follow local code for conductor size and breaker rating based on the motor nameplate amperage.
