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.
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.
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
What size breaker do you need for a 3 Ton heat pump?
My 3 ton geo unit uses a 30 amp breaker. That is probably more than adequate because it also is for the vertical loop pumps in the ground. The back-up heat strips however, use a 60 amp breaker (on my system.) I'm not sure but I would say yours probably needs that too. Good luck!
Can too much current on a breaker cause it to blow up?
The breaker will trip to the off position because of the heat caused by more amps than it is rated for. Only lightening strikes do odd things. And a loose breaker connection can arch causing limited damage to breakers. <<>> Only under extreme circumstances, like a lightning strike to the mast head. Breakers have a current interrupting rating. For a small home distribution breaker rated at 15 amps, it has an maximum RMS symmetrical interruption of 10,000 amperes. The breaker will not blow up but it will stop the current flow up to 10,000 amps. Under normal operation the breaker will trip when it reaches its operational set point, meaning that when the load current goes beyond the breakers rating, which is found on the handle, it will disconnect the circuit load.
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
Is a breaker used to heat flammable liquids?
No, a beaker does not support a flame or heat reaction, it's made of glass.
Is a 60 amp breaker correct for a 10 kw 220 heat strip?
10 kW at 220v will use 45.45 Amps. I'd recommend a 60A circuit, with a 60A breaker, but the heater or electric furnace should have "maximum fuse amps" rated on its nameplate. Above all, neverconnect wiring to a breaker that is rated higher than the maximum current capacity of the wire. In the case of 60A, use #6 AWG wire.The HVAC Veteran
