Assumes an AC three-phase L-L circuit at PF 0.85. Typing a commercial L-L voltage (208/400/480V) re-routes the result to three-phase; 277V stays on single-phase because it's the L-N lighting leg of a 480Y/277V wye; 12/24V re-routes to DC.

Formulas

DC: Watts to Amps

I_(A) = P_(W) ÷ V_(V)

700,699 ÷ 575 = 1,218.61 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

700,699 ÷ (0.85 × 575) = 700,699 ÷ 488.75 = 1,433.66 A

AC Three Phase (PF = 0.85)

I_(A) = P_(W) ÷ (√3 × PF × V_L-L), where V_L-L is the line-to-line voltage

700,699 ÷ (1.732 × 0.85 × 575) = 700,699 ÷ 846.52 = 827.72 A

Circuit Sizing

Energy Cost

Running 700,699W costs approximately $119.12 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $952.95 for 8 hours or about $28,588.52 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 700,699W at 575V is 1,218.61A. On an AC circuit with a power factor of 0.85, the current rises to 1,433.66A because reactive current flows alongside the real-power current. On a three-phase circuit at 575V the same 700,699W of total real power is carried by three line conductors at 827.72A each (total real power = √3 × 575V × 827.72A × 0.85). Each line sees the lower per-line current, but the total power is not divided across the phases, it is the sum of the three line currents operating in phase balance.

Power Factor Reference

Power factor is the main reason 700,699W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 703.56A at 575V on the three-phase L-L basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 700,699W pulls 879.45A. That is an extra 175.89A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Frequently Asked Questions

How many amps is 700,699W at 575V? expand_more

700,699W at 575V draws 827.72 amps on AC three-phase L-L at PF 0.85. For comparison at the same voltage: 1,218.61A on DC, 1,433.66A on AC single-phase at PF 0.85, 827.72A on AC three-phase at PF 0.85. Actual current depends on the load's power factor.

What power factor should I use for 700,699W calculations? expand_more

For resistive loads (heaters, incandescent bulbs, electric kettles) use PF 1.0. For motors, use 0.80. For mixed office/residential use 0.85. For computers and LED arrays the effective PF can be 0.65 or lower. Power factor only applies to AC.

Why does a 700,699W resistive heater draw fewer amps than a 700,699W motor at 575V? expand_more

Resistive loads like space heaters and toasters have a power factor of 1.0, so 700,699W at 575V on a three-phase L-L (per line) basis draws 703.56A. An induction motor at the same wattage has a PF around 0.80, drawing 879.45A on the same basis. The extra current is reactive, it does no real work but still has to flow through the conductors and breaker.

Why does AC draw more amps than DC for 700,699W? expand_more

AC circuits with reactive loads have a power factor below 1.0, so they draw extra current. At PF 0.85, 700,699W at 575V draws 1,433.66A instead of 1,218.61A (DC). That is about 18% more current for the same real power.

What is the 80% continuous load rule for 700,699W? expand_more

NEC 210.19(A) sizes the conductor and overcurrent device at not less than 125% of any continuous load (a load that runs three hours or more), equivalently 80% of the breaker rating. At 827.72A (the current the branch conductors actually carry on AC three-phase L-L at PF 0.85), the minimum breaker that satisfies this is 1035A under typical assumptions. Brief non-continuous use can run closer to the full breaker rating, but space heaters, EV chargers, and long-running appliances should be sized for the continuous case.
