What size breaker do I need for a 3 HP motor?
What size breaker do I need for a 3 HP motor? A 20 amp breaker is all you’d ever need for a 220v 3HP motor. It wouldn’t hurt anything to run 30amp circuits if you so choose, but it’s overkill.
How many watts is a 1 hp motor?
The 1 HP motor consumes 746 Watts regardless of how many hours it is running. Watt and HP are not units of energy. It will consume in 1 hour.
How many amps does a 2 HP pool pump draw?
When delivering 1/2hp to the pump, it draws 5.0 Amps. If that motor operates at its service factor of 0.8, it will draw 6.0 Amps. Most installations have motors near the maximum load.

What size wire should I use for a 30 amp breaker?
RULES OF THUMB. Many techs will repeat these rules of thumb and rely on them in all circumstances: “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”Sep 18, 2017.
Is it cheaper to run 3 phase?
Benefits and uses of a three-phase power supply Three-phase power is a four-wire AC power circuit, three power wires and a neutral wire. Although three-phase systems are more expensive to design and install initially their maintenance costs are much cheaper than a single-phase system.
What is the 3 phase power formula?
3-Phase Calculations For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000. Again, assuming unity PF and solving this equation for “I,” you get: I = 1,000kW ÷ 1.732V.
How many volts is a 3 phase?
