The tool below opens with the power already set. Change the voltage, or tap another appliance from the list, and the current updates at once with the formula beside it.
5,500 ÷ 220.
5,500 ÷ 127.
5,500 ÷ 240.
5,500 ÷ 120.
7,500 ÷ 220.
5,500 ÷ (√3 × 400), per line.
At 220 V, 25 A (5,500 ÷ 220). At 127 V, 43.3 A (5,500 ÷ 127). A heater element is a pure resistance, so the power factor is 1. That figure is the appliance current: it does not say which breaker or wire to use, which is a job for a licensed electrician.
25 A, which is 5,500 ÷ 220. At 127 V it would be 43.3 A.
No. Energy depends on power and time: 5.5 kW for one hour is 5.5 kWh at either voltage. Only the current is lower at 220 V.
No. The current is only one input. The breaker and wire depend on the installation and must be set by a licensed professional.
Use the voltage that reaches the appliance: line-to-neutral (120 V) or across two lines (240 V). Line-to-line in a three-phase system, 120 V line-to-neutral becomes about 381.1 V.
Typical nameplate powers, only as a starting point. Every model differs: the label on your appliance rules. Edit the value freely.
I = 5,500 ÷ (220 × 1) = 25 A
Running for 1 hour it uses 5.5 kWh.

Current of each appliance at 120 V and 240 V with cosφ 1 (the field above). Motors and compressors often have cosφ below 1: change the field to see the effect.
Limit of this tool. It shows the current and powers implied by the load you enter. It does not size a breaker or a cable: that depends on installation method, length, circuit grouping and temperature, and belongs to a licensed electrician or engineer following your local code.
