Can you run two 1500 watt heaters on the same 125V- 15A 60Hz power strip?

Answer 1

15 amps x 110 volts = 1650 watts

20 amps x 110 volts = 2200 watts

30 amps x 110 volts = 3300 watts

15 amps x 120 volts = 1800 watts

20 amps x 120 volts = 2400 watts

30 amps x 120 volts = 3600 watts

You can only run a single 1500 watt heater on either 15 or 20 amp line regardless of if it is 120 or 110 volts.

you may run two 1500 watt heaters on a 30 amp 110 or 120 volt line though

Just use another circuit (not just another outlet as many outlets are common to a single circuit) one circuit for each 1500 watt heater.

warning, do NOT use anything that uses the same amount of watts that your circuit can handle, for example, if you have a 120 volt outlet on a 15 amp circuit the max for that outlet is 1800, thus you need to stay WELL UNDER that amount. If you use exactly 1800 watts and the breaker doesn't trip then the resistance of the wires and connections can heat up causing a fire. The further from the breaker box = more resistance

volts times amps = watts

watts divided by volts = amps

watts divided by amps = volts

its a simple math equation. You can check your breaker box for the amps for each circuit, most recent homes are 120 volts (note that double breakers are double the current, if your household voltage is 120 then double breakers are 240 volts)

a rule of thumb... appliances require a set amount of volts, you must make sure you plug it into the right voltage, the appliance itself will take care of how many amps it draws, thus how many watts it uses. Most appliances will list the voltage required and the amps that it draws somewhere near the power cord.

Answer 2

110 volt heater on 220 volts

The load is a resistive load and as such it is governed by Ohm's law. Current is directly proportional to the voltage and inversely proportional to the resistance. As the voltage goes up so does the current. An example, I = W/E, 1000 watt heater at 110 volts = 9 amps. R = E/I = 110/9 = 12 ohms of resistance in the 1000 watt heater. Now take the 1000 watt heater and using the same formula and at 220 volts. I = E/R, Amps = Volts / Resistance. 220/12 = 18 amps. As you can see ohm's law holds true, the current is directly proportional to the voltage. To answer the question, NO, a 110 volt heater will not run on a 220 volt circuit. It will draw double the current it is designed for and the thermal safety trip will shut the unit off. Bypassing the thermal trip will elevate the temperature of the heater to a combustible state and this can cause a fire if the surrounding material is of a combustible material. Connecting to a 15 amp breaker will trip the breaker.

Answer 3

A 1500 watt heater operating on 120 volts has an amperage of A = W/V. Amps = Watts/Volts = 1500/120 = 12.5 amps. As you can see if you plug two heaters into the power strip the trip on the power bar will trip or if no trip on the power bar then the breaker feeding the power bar will trip.

Answer 4

It depends on the voltage of the supply and the correct required voltage for the heater, which should be the same. But 1500 watts is not a very heavy load so a heavy duty power cord should be all right. At 120 volts the cord should be able to supply 12.5 amps.

Answer 5

You can draw up to 3,300 watts from a 220V 15 Amp circuit. So the 1,800 watts you are drawing is fine.

Answer 6

You would be using a maximum of 12.5 amps. Your should not hook anything else to that line.

Answer 7

Each heater should draw a little over 4 Amps. As long as you have nothing else on circuit you should be okay. Typically you want to be at about 80% or rated load.

Answer 8

Yes you can, as long as you don't use the full power, and always keep it in low.
