How Many Amps Is 6,002 Watts at 120V?

At 120V, 6,002 watts converts to 50.02 amps using the AC single-phase formula (Amps = Watts ÷ (V × PF)) at PF 1.0 for a resistive load. AC resistive at PF 1.0 and the DC baseline land on the same number at this voltage.

At 50.02A, the NEC 210.19(A) continuous-load sizing math (125% of the load, equivalently 80% of the breaker rating) points to a 70A breaker as the smallest standard size that covers this load continuously. A 60A breaker is the smallest standard size the raw current fits under, but it is non-continuous-only at this load.

Assumes an AC single-phase resistive load at PF 1.0. 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)

6,002 ÷ 120 = 50.02 A

AC Single Phase (PF = 0.85)

I_(A) = P_(W) ÷ (PF × V_(V))

6,002 ÷ (0.85 × 120) = 6,002 ÷ 102 = 58.84 A

Circuit Sizing

Breaker Sizing

NEC 240.6(A) standard ampere ratings for branch-circuit and feeder breakers start at 15, 20, 25, 30, 35, 40, 45, and 50A and continue at 60A and above for feeder and large-appliance circuits. At 50.02A, the smallest standard breaker the raw current fits under is 60A, but that breaker only covers 60A non-continuously; NEC 210.19(A) requires conductor and OCP sized at 125% of any continuous load (equivalently 80% of breaker rating), so for a continuous load the smallest compliant breaker is 70A. Final selection still depends on the equipment nameplate, whether the load is continuous, conductor ampacity, and local code.

Breaker Size	Max Continuous Load (80%)	Status for 50.02A
40A	32A	Too small
45A	36A	Too small
50A	40A	Too small
60A	48A	Non-continuous only
70A	56A	OK for continuous
80A	64A	OK for continuous
90A	72A	OK for continuous
100A	80A	OK for continuous

Energy Cost

Running 6,002W costs approximately $1.02 per hour at the US average rate of $0.17/kWh (rates last reviewed April 2026). That is $8.16 for 8 hours or about $244.88 per month. See detailed cost breakdown.

AC Conversion Detail

The DC baseline for 6,002W at 120V is 50.02A. On an AC circuit with a power factor of 0.85, the current rises to 58.84A because reactive current flows alongside the real-power current.

Circuit Type	Formula	Result
DC	6,002 ÷ 120	50.02 A
AC Single Phase (PF 0.85)	6,002 ÷ (120 × 0.85)	58.84 A

Power Factor Reference

Power factor is the main reason 6,002W draws more current on AC than DC. At PF 1.0 (pure resistive, like a heater), the load pulls 50.02A at 120V on the single-phase basis the rest of the page uses. At PF 0.80 (typical induction motor), the same 6,002W pulls 62.52A. That is an extra 12.5A just to overcome the reactive component. Use the typical values below as a starting point, not for precise engineering calculations.

Resistive (heaters, incandescent)	1	50.02 A
Fluorescent lamps	0.95	52.65 A
LED lighting	0.9	55.57 A
Synchronous motors	0.9	55.57 A

Induction motors (full load)	0.8	62.52 A
Computers (without PFC)	0.65	76.95 A

Frequently Asked Questions

How many amps is 6,002W at 120V? expand_more

6,002W at 120V draws 50.02 amps on AC single-phase at PF 1.0 (resistive). For comparison at the same voltage: 50.02A on DC, 58.84A on AC single-phase at PF 0.85. Actual current depends on the load's power factor.

How much does 6,002W cost to run per hour? expand_more

At the US residential average of $0.17/kWh (last reviewed April 2026), 6,002W costs $1.02 per hour and $8.16 for 8 hours. Rates vary by utility and time of day.

What power factor should I use for 6,002W 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 6,002W resistive heater draw fewer amps than a 6,002W motor at 120V? expand_more

Resistive loads like space heaters and toasters have a power factor of 1.0, so 6,002W at 120V on a single-phase AC basis draws 50.02A. An induction motor at the same wattage has a PF around 0.80, drawing 62.52A 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 6,002W? expand_more

AC circuits with reactive loads have a power factor below 1.0, so they draw extra current. At PF 0.85, 6,002W at 120V draws 58.84A instead of 50.02A (DC). That is about 18% more current for the same real power.
