How do I convert amps to watts at 230V?

Multiply amps by 230: Watts = Amps × 230 × PF. For a kettle drawing 13 amps at 230V with PF 1.0: 13 × 230 = 2,990 watts. The UK standard ring main circuit uses a 32A breaker, handling up to 7,360 watts.

What is the maximum watts on a UK 13A socket?

A UK BS 1363 socket with a 13A fused plug can deliver 2,990 watts maximum (13 × 230). In practice, this limits individual appliances to about 3 kW. For higher loads like electric showers (7–10.5 kW), a dedicated circuit with higher-rated MCB is required.

Is European voltage 220V or 230V?

The EU harmonized to a nominal 230V ±10% in 2003 (EN 50160). Previously, most of continental Europe used 220V and the UK used 240V. The wide tolerance means actual voltage can range from 207V to 253V. Both old 220V and 240V equipment works safely within this range.

Do UK appliances use power factor?

Resistive UK appliances (kettles, toasters, immersion heaters) have PF ≈ 1.00. Motor-driven appliances (washing machines, refrigerators, air conditioners) have PF ranging from 0.75 to 0.95. For load planning on a consumer unit, accounting for PF gives more accurate watt calculations.

How many amps does a UK electric shower use?

A 9.5 kW electric shower at 230V draws 9,500 ÷ 230 = 41.3 amps. This requires a dedicated 45A MCB and 10mm² cable. Higher-powered showers (10.5 kW) draw about 45.7 amps. Always check the installation complies with BS 7671 wiring regulations.

What MCB size do I need for my watt load at 230V?

Divide your total watts by 230 to get amps, then select the next standard MCB size above. For example, 4,600W ÷ 230 = 20A, so a 20A Type B MCB would suit a resistive load. For motor loads, use a Type C MCB to handle startup inrush. Always have an electrician verify the circuit design.

Quick answer

Use this calculator to convert AC current into real watts with voltage and power factor.

Single-phase AC loads can be resistive or inductive. Resistive loads may be near PF 1.00, while motors, compressors, and HVAC equipment often need a lower power factor.

Watts = Amps x 230V x PF

Inputs to check before calculating

Use the correct nominal voltage for the circuit.
Enter measured current or nameplate running current.
Use realistic PF for motors, compressors, and transformer loads.
Compare the result with breaker and continuous-load limits.

Example: 10 amps at 230 volts

At 230 volts, 10 amps equals 2,300 watts before AC power-factor adjustments. Formula: 10 A x 230 V = 2,300 W.
