To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
The breaker size for a 10 KVA electric heater would depend on the voltage it operates at. For example, for a 240V heater, you would need a 41.67 Amp breaker (10,000 VA / 240V = 41.67 A). It is important to consult with a licensed electrician to ensure the correct breaker size and electrical setup for your specific heater.
A 1500 watt bathroom exhaust fan heater should be connected to a 15 amp breaker to ensure proper protection against overloads. This is calculated by dividing the wattage (1500 watts) by the voltage (typically 120 volts for residential circuits) to determine the amperage (12.5 amps in this case, which you would round up to the nearest standard breaker size).
To run a 500 watt 240 volt heater, you would need a 2.08 amp breaker. This can be calculated by dividing the wattage by the voltage (500W / 240V = 2.08A). You would typically round up to the nearest standard breaker size, which in this case would be a 3 amp breaker.
A 15000 watt 240 volt heater would require a 62.5 amp circuit breaker. To accommodate this exact load, you would typically use the next standard breaker size above 62.5 amps, which is a 70 amp breaker to ensure safety and proper operation of the heater.
For a 2500 watt water heater operating at 120 volts, you would need a 20 amp breaker. This ensures the breaker can handle the load without tripping.
