What size breaker is needed for a 20 kva heat strip?
To determine the appropriate breaker size for a 20 kVA heat strip, you need to calculate the current. For a 240V system, the current is approximately 83.3 amps (20,000 VA / 240V). It’s standard practice to use a breaker rated at 125% of the continuous load, so a 100-amp breaker would be suitable for this application, providing a safety margin. Always consult local electrical codes and a qualified electrician for compliance and safety.
Is a 60 amp breaker enough to for a 10kw heat strip?
Answer for USA, Canada and countries running a 60 Hertz supply service.On heating elements of higher wattage 240 volts is usually the working voltage. 10000/240 = 41.6 amps. A #8 copper wire with an insulation factor of 90 degrees C is rated at 45 amps. Code states that the conductor can only be loaded to 80% so 45 x .8 = 36 amps. A #6 copper wire with an insulation factor of 90 degrees C is rated at 65 amps. 65 x .8 = 52 amps. No. Power = Voltage X Current.....so a 10,000 watt heat strip will draw 10,000 watts / 120 volts = 83 ampsNot so fast.Actually, it depends on the manufacturers guidelines. My 10KW heat strip, in my hvac system, is rated ( by the manufacturer ) at 41.7 amps.8 AWG wire is rated at 40 amps. 6 AWG wire at 50 amps.I used 6 AWG wire and a 50 amp breaker. I passed the electrical inspection.
How do you use a strip heater?
A strip heater is typically used to heat surfaces for applications like plastic bending or sealing. To use a strip heater, you would place the object to be heated on top of the strip heater and turn it on. The heat generated by the strip heater will soften the material, allowing it to be formed or sealed as needed.
What would cause a 15 amp circuit breaker to throw after 5 hours?
Operating a breaker on a continuous current, close to the breaker's tripping point can cause this condition. Because the breaker is a thermal device the heat builds up over a time period. Check the breakers on either side of the faulting breaker. If these breakers are also warm from use they take away the heat sink effect and do not let the faulting breaker cool down. Check the current of the load to see how close you are operating to the breakers trip point. Over time the trip setting of the breaker can become lower to a point where it will not reset. Changing the breaker out should rectify this non resetting condition.
Can circuit breakers help to prevent building fires?
Breakers limit the current on the conductor to a safe level, too many appliances plugged in. You trip a breaker, hopefully you then transfer load to another circuit. Breakers use two different methods to accomplish this, one uses a bimetallic strip and the current passes directly through, too high a current causes the strip to deflect. It acts on a mechanism much like the sear in a guns trigger, the deflection pulls the trigger causing a spring to open the contacts and turn off the circuit. Another type is thermal magnetic, current passing through the breaker causes a magnetic field to act on a coil tripping the breaker. When breakers are wired and work properly they prevent fires!Bending metal opens a switch
How many btu's is in 15kw heat strips?
51210 Btu's in 15kw heat strip. 3.414 * 15000= 51210

How can you tell if a unit is a heat pump or a heat strip unit?
A heat pump pulls the air back through and recylces it to make heat. A heat strip is just air being pushed across the heat strip to make the air warm.
What size of wire do you need for 5 kw heat strip?
120 15 amp service ? 210 7 amp service ?
What is the use of a strip heater?
Say you have water travelling through tubes, and you wish to heat that water as it goes... Attaching a strip heater around that tube would enable you to regulate the temperature of the water passing through.
What is air cicuit breaker?
Assuming you meant a not air. A circuit breaker is a device that prevents a circuit from overloading. When the current in a circuit reaches a predefined limit, the breaker trips and opens the circuit, stopping an overload. Commonly this is done using a strip of metal with one type of metal on one side and a different one on the other. The two metals have different coefficients of thermal expansion. When the current level is reached, the strip overheats. Because one metal expands more with heat the strip bends(high coefficient of thermal expansion on the convex side). This bending opens the circuit and prevents overload.
Is it possible to heat a strip of rubber?
It is possible to heat anything.
What is cheaper to operate a heat strip unit or a heat pump?
the heat pump is cheaper but the pump does not work as well when its below 40 out side thats when you want to run heat strip
How to wire a 5 wire thermostat properly without a diagram?
depends on whether thermo used on gas or elec. unit, heat pump, strip heat, etc. red wire is hot wire. White wire goes to heat. yellow wire goes to outdoor unit contactor. green wire goes to indoor fan. blue or brown wire goes to reversing valve on outdoor unit.
Air conditioner blows circuit breaker when heating?
If you have a heat pump and the breaker blows in heat cycle then you probably also have auxiliary electric heat which is drawing too much current because of a faulty heater element.
You bought a rheem heat pump what gauge wire should you use for a 80amp breaker?
My heat pump was professionally wired when built in 2004. Wire is No. 4 AWG with 80 amp breaker
What causes a circuit breaker to trip?
A circuit breaker trips when there is an overload of electrical current flowing through the circuit, causing it to heat up and trip the breaker to prevent damage or fire.
