# FAQ: How Many Amps Does A 1000 Watt Heater Draw?

## How many amps does a 1500 watt heater draw?

A 1500 watt space heater (on high setting) will draw 12.5 Amps. When a few lights or a television are on the same circuit, the 15 Amp limit is quickly reached and the breaker will trip.

## What size breaker do I need for a 1500 watt heater?

A 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps. Include the current draw of any other devices on the circuit when calculating the breaker size.

## How many electric heaters can I run on a 20 amp breaker?

A 20-amp breaker can support any combination of heaters up to a total of 3,840 watts. For example, using a single thermostat, the breaker could support two 1500-watt heaters or three 1000-watt heaters.

## How many watts can I run on a 20 amp circuit?

A 20-amp breaker can support up to 2,400 watts on a single circuit. The safe maximum for a 20-amp circuit is 1,920 watts, but circuits should not be loaded to more than 80 percent of their maximum capacity.

## How many amps is 2400 watts at 240 volts?

2400 Watts / 10 Amps = 240 Volts.

## How many watts is 30 amps?

The formula is 30 amps X 120 volts = 3,600 watts.

## How many watts is 15 amps?

The circuit and circuit breaker that you tripped have a capacity of 15 amps, or 1,800 watts (15 amps x 120 volts = 1,800 watts).

## Does a 1500 watt heater use much power?

Most electric heaters use 1,500 watts, but some are slightly less or slightly more. Since 1,000 watts equals 1 kilowatt, that means your heater uses 1.5 kilowatts of power. However, your electric bill is measured in kilowatt hours, which is the amount of energy used while running a 1-kilowatt appliance for one hour.

## How many receptacles can be on a 20-amp circuit?

Although the National Electric Code (NEC) doesn’t directly rule on limiting outlet installments on your circuit, it is crucial to learn its power draw restrictions. In general, you should have a maximum of 10 outlets on a 20A circuit.

## How many amps does a oil filled heater pull?

A 1500 watt space heater (on high setting) will draw 12.5 Amps. When a few lights or a television are on the same circuit, the 15 Amp limit is quickly reached and the breaker will trip. Oil heaters by far are more cost effective and safe.

## Why does my electric heater keep tripping the breaker?

Common Reasons Why a Heater Might Trip the Breaker The most likely reason is that the heater is drawing too much current and overheating that circuit. This can be dangerous, so the breaker shuts off to protect you. A second reason is that you might have too many other appliances on the circuit.
