My space heater keeps blowing the breaker.

Basic- 15 amp circuuit should not hold more than 1440.00watts, or 12 amps ( 1440watts / 120v= 12 amp). you should load the circuit for lighting or continual use more than 75%. the same for 20 amp circuits. (1800 watts/120v=15amps). Check the back of the space heater. It should the watts listed.

If it worked before the space heater may well now have a ground fault or shorted circuit due to overheating.Its also common for the connecting leads on the space heater to overheat and break off and touch the outter casing.
You need to check this with an insulation resistance tester (megger) to be sure and check the resistance of the heater with an ohm meter.If it worked before an Electrician will verify these tests for you.

check the NEC (national electrical code)
If I remember right the general rule of thumb is that you should have no less than a 20 amp breaker for every six outlets. You could have a weak breaker or your space heater is bad. also make sure you do not have that circuit running to many high current items............

High amperage devices should have their own circuit. A properly wired house should have one circuit dedicated to each high amperage electrical device. Also, never ever plug your computer into the same circuit as a space heater, television, or any other high amperage device or device that uses a electro-magnet as part if its electronics, as it would damage your computer over time.

Watts = Amps times Volts.
A 1000 watt heater will draw about 8.3 amps at 120 volts.

Your electrical energy meter straight away measures KWhrs. the unique motor variety has 2 coils: one produces a magnetic container proportional to the present, one proportional to the voltage. they're arranged in this form of style that they act like an induction motor on an aluminium disk, and the torque on the disk is proportional to the made from voltage and modern. The disk turns a machanical dial which merely counts the revolutions. there's a magnet close to the disk that's adjusted to brake the rotation that's used to calibrate the meter. with the aid of fact the rotation stress on the disk is proportional to the prompt made from the the voltage and modern, merely actual potential will pass the disk, reactive potential (potential flows one way then the different) creates an popular of 0 torque, so it doesnt sign in on the counter. extra recent meters have digital circuitry which straight away senses the prompt modern and voltage and calculates the actual potential. uncomplicated residential potential, you're merely charged for actual potential, reactive potential isn't seen. large commercial and business clientele are charged for actual potential too, yet could desire to be required to maintain a undeniable potential element, or they could sell reactive potential lower back to the appliance from time to time (wind farms are used for this particularly in many circumstances), reckoning on their contract!

Well dont' forget that in AC that P=VI will not work. You have to multiply this times the power factor.
