In the United States and according to the NEC, in commercial and industrial installations, you may have as many as 13 receptacles on a 20 amp circuit. There is no limit to the number of receptacles you can place on a circuit in a home.

∙ 6y agoAs you did not specify the voltage of the circuit, I will I will assume your heaters are 110 volt portable heaters not 220 volt baseboard heaters.
Each heater will draw 1500 watts / 110 volts = 13.64 amperes.
As this is more than half of the 20 ampere rating of the circuit, you can only run one of these heater.

∙ 12y agoEach 1000 watt unit will draw about 1000/240 = 4.2 amps. You want to be around 80% of 20 amps or about 16 amps. So you don't want to exceed 3 units.

How many amps will a 230 vac 3500 watts heater draw?
To calculate the amperage, you can use the formula: Amperage (A) = Watts (W) / Voltage (V). In this case, the heater draws 3500 watts and operates at 230 volts. So, the amperage will be approximately 15.22 amps.
What is the total energy used if an average person uses a tv computer refrigerator toaster light bulbs fan air conditioner space heater hair dryer Xbox Wii oven stove and a micowave?
TV 150 watts, computer 200 watts, laptop 40 watts, refrigerator 15 watts average, toaster 900 watts, light bulbs 15-150 watts, fan 20 watts, a/c 3000 watts, space heater 2000 watts, hair dryer 1000 watts, oven/stove 3000 watts, microwave 1000 watts. Total energy used is equal to the watts times the time. The total energy in units or kWh is the power in kilowatts times the time in hours.
How a electric heater works 2 references?
An electric heater is a resistor that dissipates electric power when a voltage is connected across it and a current flows through it. The amount of power in watts is equal to the voltage times the current in amps. Typical space heaters for use in the home are 1.5 kW to 3 kW to heat a single room.
How much power does a heater use?
Check the appliance's specifications on the strip, tag or plate that is usually fixed either on the back or somewhere on the frame. On there you will find its required operating voltage and wattage that it draws.If your home has 240 volt line voltage just divide the watts by the volts for the answer.Example: a 2400 watt water heater for a 240 volt line using the formula watts / volts = amps would give you 10 amps. For a 120 volt appliance it would be 20 amps.
How many watts does a small ceramic heater use?
A ceramic heater uses the same amount as a regular heater. Most heater use 1500 watts so in one hour a 1500 watt home heater will use 12.5 amp hours.
A 2000 watt heater connected to a 120 volt circuit will draw a current of?
Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps
How many watts does a space heater use?
Depends upon the size, but it will be listed on the space heater for whatever speed you set. Sometimes the nameplates are difficult to find and might be located on the bottom of the space heater.

What are the uses of wattmeter?
Wattmeter is an intrument which is used to measure the power consumption of an Electric circuit or an appliance which is connected to the supply in terms of Watts.
Where can I find circuit breakers?
Lowes and Home Depot carry circuit breakers as well as the wiring and box. Circuit Breakers come in several watts, so be sure you get what is appropriate for your living space.
If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous

1 household circuit connected to three electrical parallel outles are connected to 3 devices an 800watt electric kettle a 60watt trouble light and a 1000-watt toaster oven will it trip a 15amp fuse?
The total wattage of those 3 devices is 1860 Watts. Divide the Watts by the 120 Volts in the circuit and you get 15.5 Amps. That exceeds the 15 Amp fuse.
What size space heater is needed for a 10 by 12 foot room?
In order to find the correct size space heater, first you need to find the AREA of the room, which is 10 x 12 = 120 square feet. Then you multiply this by 3.41 BTU's = 4092 BTU's. A STANDARD SPACE HEATER will be appropriate (a standard space heater is appropriate for up to 5100 BTUs or 1500 watts). If there are a lot of windows or the ceilings are higher than normal (normal is from 8 ft to 10 ft tall ceilings), than you may need a larger space heater, but in this case, a standard sized space heater will do.
An electric heating element is connected to a 110v circuit of a 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
110v x 3.2 a=352 watts time 5= 17600.00 watts or 353 watts per hour
