How Many Amps Will 1500 Watts Draw? A Sample Circuit Calculation Using the W ÷ V = A variation of Ohm’s law, you can calculate that 1,500 watts ÷ 120 volts = 12.5 amps.
What size breaker do I need for a 1500 watt heater? A 1500 watt heaters on a 120-volt circuit needs a breaker. A breaker with the next highest rating of 20 Amps is needed because a 15-amp breaker would be too small. The current draw of any other devices on the circuit should be included in the calculation.
Can a 15 amp circuit handle 1500 watts? A 15 amp breaker can handle 1500 watts or 12.5 amps of draw on the circuit continuously. This is assuming it is 120 volts. It is 80 percent of the capacity the breaker can handle. However if you take the same circuit and double the voltage to 240 volt you can also double the wattage to 3000 watts.
Does a 1500 watt heater need its own circuit? Space heaters can range from 400 to 1500 watts, but a good rule of thumb is that the maximum watts per outlet should never exceed 1500 watts. In other words, yes, your 1500-watt heater needs its own circuit.

How much electricity does a 1500 watt use?
1,500W heater will consume 1,500 watts of electricity. Simple. If you run it for 1 hour, it will consume 1.5 kWh of electricity.
How many amps does a 1500 W heater use?
According to google – A 1500 watt space heater (on high setting) will draw 12.5 Amps.
How much will a 1500 watt heater heat?
1500 watts will heat spaces up to about 150 square feet and can help you stay warm and toasty in a medium-sized room, office, kitchen, or modest-sized living room.
Will a 1500 watt heater trip a breaker?
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.
Can my outlet handle 1500 watts?
Know the amount of power you’re placing on an outlet or circuit. Some recommend each outlet or circuit should not exceed 1,500 watts. Major appliances (refrigerators, dryers, washers, stoves, air conditioners, etc.) should be plugged directly into their own wall outlet since they are heavy power users.
How many watts can you run on a 20 amp breaker?
Now, a 20 amp breaker generally can support 2,400 watts per single circuit.
Will 1800 watts trip a breaker?
Since this uses 1800 Watts, 120 Volts would yield 1800 / 120 = 15 Amps, which is the typical circuit breaker rating for most outlets (excluding ranges, refrigerators, and so on). Typically you can use more than 15 amps on a branch circuit for a period of time, depending on how much over the rated limit you are.
Can I run space heater on 15 amp breaker?
In total a 120 volt plug in space heater uses up to 12.5 amps of a 15 amp circuit. This is assuming it is a 1500 watt space heater. One can not have to space heaters plugged into the same circuit as it is too much of a power draw. Each space heater requires a dedicated circuit all by itself.
How many watts can a 30 amp breaker handle?
30-amp 240-volt circuit: 30 amps x 240 volts = 7,200 watts.
How much electricity does a 1500W heater use?
A 1500W space heater uses 1.5 kilowatts of electricity per hour, or 1.5 kWh.
How much does it cost to run a 1500 watt heater for 8 hours?
So I did the research, and even made a free calculator. On average, a 1,500W heater costs around $0.20 per hour to run on high. This adds up to a cost of $1.60 for 8 hours a day, and $48 per month. The running costs depend on your electric heater’s power, running time, heat settings, and your electricity price.
How big of a room can a 1500 watt heater heat?
As a rule of thumb, you’ll need roughly 10 watts of heating power for every square foot of floor area in the room. This means that a 1,500-watt heater can be the primary heat source for an area measuring up to 150 square feet.
Will a 1500 watt heater heat a garage?
Garage Size A good rule to follow for choosing an adequate garage heater is for every 10 watts of output, you can heat 1 square foot of space. For instance, a 150-square-foot garage or shop will be fully heated by a 1,500-watt electric garage heater. Also, keep in mind the amount of actual space you use.
How many square feet will a 1500 watt heater cover?
A 1,500 watt heater can heat up to 150 square feet. It’s the same as a 10-by-15 foot room, an 11-by-14 or one sized to 12-by-12 1/2 feet and a standard 8-foot ceiling.
How many heaters can you run on a 20 amp circuit?
So a 240-volt circuit running on a 20-amp, double-pole breaker, can have any combination of heaters up to 3,840 watts. For example, using just one thermostat, you can install: Two 1,500 watt heaters, or. Three 1,000 watt heaters, or.
Is 1500w too much?
As a rule of thumb, it’s safest to stick to a maximum load of 1,500 watts per outlet or circuit. The number of things you can plug into one outlet depends on the wattage of each device or appliance you want to plug in.
How many watts can a GFCI handle?
The maximum power (wattage) allowed a GFCI circuit can be found by multiplying the GFCI circuit breaker connected to the electrical circuit with its rated voltage. For example, if you use a 15 amp circuit breaker in a 120 volt circuit, your maximum power allowed will be 1800 watts.
How many watts does a fridge use?
The average home refrigerator uses 350-780 watts. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it. Different types of fridges have different power requirements.
How many amps does a TV use?
The average American TV is 50 inches and uses 0.95 amps at 120 volts. That works out to an average TV power consumption of 113 watts. In a given year, the average TV will use 142 kWh and cost a little over 17 dollars (assuming 5 hours of use per day).
