How much current is flowing through an oven that uses 1200 watts on a 120 volt circuit?

Microwave ovens consume power at a rate of 650–1200 watts, which corresponds to a current of 5.4–10 amps at 120 volts AC. To convert power to current, use the equation …

How much electricity does a heater use?

Most space heaters use on average 1,500 Watts of electricity and cost about 15¢ an hour to operate. While that may not sound like much, it can add up quickly if heaters are left on for several hours a day.

How much electricity does an electric heater use?

Your electric heater wattage tells how much electricity is needed to power it. Most electric heaters use 1,500 watts, but some are slightly less or slightly more. Let’s go ahead and assume you’ve got a 1,500-watt heater. Since 1,000 watts equals 1 kilowatt, that means your heater uses 1.5 kilowatts of power.

What is the difference between a 120 volt and 240 volt heater?

A 1500 Watt heater will cost the same to run whether it is 120 or 240 Volt. 240 Volt heating circuits are more common because it reduces the Amp draw on your breaker/fuse panel, as the chart shows, you can place more heaters on a 20 Amp 240 Volt circuit (maximum of 3840 Watts) versus a 120 Volt circuit (maximum of 1920 Watts).

What is the power consumption of a 720 watt heater?

The power consumption of the two sample heaters analysed ranged from 720 watts to 890 watts. The 720 watt unit provides 3.6 units of heat per unit of electricity consumed, and the 890 watt (0.89 kW) unit provides 2.9. Energy cost of the 720 Watt unit: $0.0864 per hour.

How many amps can a heating circuit have?

The above circuit sizing is based on 75C wire and for reference only. Always consult local codes for proper sizing. According to the National Electric Code heating circuits are considered a continuous load and therefore must be derated by 25\%. (For example: a 20 Amp heating circuit cannot have more than 16 Amps of load connected.)
