Single Phase wiring installation is the most common wiring in residential buildings. In Single Phase supply (230V in UK, EU and 120V & 240V in the US & Canada), there are two (one is Line (aka Phase, Hot or Live) and the other one is Neutral) incoming cables from the utility poles to the kWh energy meter and then directly. If the cable type is single-core, this parameter means sets of cables. That is, x number of sets (of two) for single-phase. And x number of sets (of three) for three-phase. Earth cable parameters. Earth core type: Only copper is currently supported. Earth conductor size: Select a cable size or select Auto. Auto will automatically select a cable. You have 375 feet of #6 wire buried between the service entrance and the wellhead. A new 3HP 230V single phase pump will be installed to replace a smaller pump. The new pump will be set at 200 feet below the wellhead. What wire gauge is suitable

Single phase motor horsepower shall be from 1/6 hp to 10 hp and 115 volts to 230 volts. 6. Three phase horsepower shall be from 1/2 hp to 500 hp. 7. Three phase 115 volt motors shall be 1/2 hp to 2 hp. 8. Three phase Motors from 3 hp to 200 hp shall be 200 volts to 575 volts. 9. Three phase Motors from 250 hp to 500 hp shall be 460 volts or 575. Table 430.248 lists a 1 HP single phase motor operating at 230 volts as 8 amps. 430.52 (A). The motor branch circuit short-circuit and ground-fault protective device shall comply with 430.52 (B), 430.52 (C) or 430.52 (D) as applicable. 430.52 (C) (1) A full load current for a 5hp single phase AC motor on 230v is 28 amps. So 10ga. wire with a 30 amp breaker will be fine. 5hp....that must be a monster compressor. My 1hp running on 230 runs real efficiently I can't figure what size breaker to use for my install. Here's what I've got-- it's a 3.7 hp single phase 230v with fully load amp 17.2a and it's continuous. I went to 310.15(b)(16) THHN for my wire size (125% x FLA=21.625) so therefore I can get away with a copper 12awg but I got 10's in the conduit already

Is the motor actually drawing 6.6 A from each hot wire (for a total of 13.2 A), or is it drawing 3.3 A from each hot wire? If it's 6.6 A from each hot wire, it seems the classic current x voltage = power equation is misleading for 240 V single-phase circuits. Update: to clarify, this question applies to 120 V and 240 V current in the US A full load current for a 5hp single phase AC motor on 230v is 28 amps. So 10ga. wire with a 30 amp breaker will be fine Select the type conductor wire material, the circuit voltage and the phase of the circuit. Enter the total amperage on the circuit; also enter one half of the total length of the circuit. A sample of 120 volts, single phase, copper wire, 144 feet (one half of a 288 foot circuit) with 10 amps load on it yields a number 10 awg wire size. Our. 2. 30 amp circuit takes 10ga wire [unless very long runs, which you don't have]. 10ga wire at 220V 25A will drop voltage less than 2% in 90 feet, so your 45 feet will be no problem. At 30A load 2% loss comes at 75 feet. BruceT. Edited 8/22/2007 11:13 pm ET by BruceT99
