The Core Formula: Kilowatts to Amps

The formula varies slightly depending on the current type:

#1. DC Systems:

I(A)= P(W)​/V(V)

Example: A 1.5kW (1,500W) DC motor running on 12V draws:

12/1500​= 125A

#2. AC Single-Phase:

I(A)= P(W)/V(VPF

PF = Power Factor (typically 0.8–0.95)

#3. AC Three-Phase:

I(A)=P(W)​/√3​×V(VPF

Common Mistakes When Converting kW to Amps

Avoid these errors to ensure accurate results:

  • Ignoring Power Factor (AC Systems): Assuming PF = 1 can lead to undervalued current by 20–30%.
  • Mixing Voltage Types: Using line-to-line (L-L) voltage for single-phase systems or vice versa.
  • Unit Confusion: Forgetting to convert kW to watts (1 kW = 1,000W) or milliwatts (1 mW = 0.001W).
  • Three-Phase Formula Errors: Using √3​ for line-to-neutral (L-N) voltage instead of line-to-line (L-L).

Practical Example: Home Appliances

Imagine installing a 2kW water heater in a 230V AC single-phase system with a power factor of 0.9:

  • Convert kW to watts: 2kW=2,000W2kW=2,000W
  • Apply the formula:

I= 2000/230×0.9= 2000/207 ≈ 9.66A

  • Result: Use a 10A circuit breaker for safe operation.
