An electric range typically uses around 40-50 amps when operating at its maximum capacity. This can vary based on the specific model and power requirements of the range.
A normal range for a home appliance device usually is wired with a forty amp capacity wire number eight, which is connected to a two-pole forty amp breaker.
To calculate amperage, use the formula: Amperage = Power (Watts) / Voltage. For a 16 kW electric range, assuming a standard household voltage of 240V in the US, the amperage would be approximately 67A.
Electric water heaters typically use between 15 to 20 amps of electrical current. The exact amperage can vary depending on the size and model of the water heater.
The amperage of an electric heater depends on its power rating in watts and the voltage it operates on. To determine the amperage, divide the wattage by the voltage (Amperes = Watts / Volts). For example, a 1500 watt electric heater running on 120 volts would use 12.5 amperes (1500 watts / 120 volts = 12.5 A).
The formula you are looking for is Amps = kW x 1000/1.73 x E x pf. Use .84 for a power factor value.
An electric piano typically uses around 120 volts, 15-30 watts, and 0.5-1 amp, depending on the model and usage. It's important to check the specific specifications of your electric piano to ensure compatibility with your electrical system.
