What size circuit breaker and wire should be used for two 1500 watt livestock water tank heater at 300 ft from power source?
You have a 3000 watt load at 300 ft from the power source. Assuming a 240 volt supply voltage, the current is 12.5 amps. The voltage drop should be 5% or 12 volts, so the total resistance should be 1 ohm or less.
With 600 ft of wire (2 wires) the allowable resistance per foot is 1/600 ohms, or 0.0047 ohms per metre. A 1 sq.mm. wire has a resistance of 0.0168 ohms/metres, so you need wire of 0.0168/0.0047 sq.mm., that is 3.57 sq.mm. Use wire with a cross section of 4 sq.mm. That is 11 AWG or 13 SWG. If these sizes are unavailable, use the next larger size (smaller gauge number).
What else can I help you with?
What should a 3 kW immersion heater circuit must be provided with?
A 3 kW immersion heater circuit should be provided with a dedicated 15 Amp circuit that is protected by a 15 Amp circuit breaker and wired with appropriately sized cables (typically 14 AWG for residential wiring in the US). Additionally, a Ground Fault Circuit Interrupter (GFCI) protection may be required for safety.
Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
Why does my 1500 watt heater consistently blow my 15 amp breaker fuse?
A 1500-watt heater draws approximately 12.5 amps, which is close to the 15-amp capacity of the breaker. If there are other appliances drawing power on the same circuit, it could easily trip the breaker. You may need to run the heater on a circuit with fewer devices drawing power to prevent overloading the breaker.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
Can you use a 20 amp breaker if the amp rating on a heater is 21 amp?
No, it is not safe to use a 20 amp breaker for a heater with a 21 amp rating. The breaker should be rated at least equal to or higher than the amp rating of the appliance to prevent overheating and potential fire hazards. It is recommended to use a 25 amp breaker for a 21 amp heater.
Where is the circuit breaker for a hot water heater?
The best way to determine which circuit breaker is for the water heater is with a voltage meter, It is suppose to be only one circuit breaker, but in a faulty application it could be two breakers
What information should be included on circuit breaker labels?
Circuit breaker labels should include the voltage rating, current rating, type of circuit, and the location of the circuit breaker.
Why is heater is not keeping house warm?
A heater may not be keeping a house warm because it is too small for the space. An older heater may not be performing as it should. If you are getting no heat from the heater, you may have blown a fuse and should check the circuit breaker box.
What should I do if the water heater light is not turning on?
If the water heater light is not turning on, first check if the power supply is connected and the circuit breaker is not tripped. If those are fine, the issue may be with the heater's components, and you should contact a professional for repair or replacement.
How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker
What should you do to the surge strip if the circuit breaker fails to reset?
You should replace the surge strip if the circuit breaker fails to reset.
What should a 3 kW immersion heater circuit must be provided with?
A 3 kW immersion heater circuit should be provided with a dedicated 15 Amp circuit that is protected by a 15 Amp circuit breaker and wired with appropriately sized cables (typically 14 AWG for residential wiring in the US). Additionally, a Ground Fault Circuit Interrupter (GFCI) protection may be required for safety.
What should I do if my circuit breaker popped?
If your circuit breaker has tripped, you should first try to identify the cause of the overload by unplugging devices or appliances connected to that circuit. Then, reset the circuit breaker by flipping the switch back to the "on" position. If the circuit breaker continues to trip, it may indicate a more serious electrical issue that requires professional assistance.
Must wires be connected to breaker box?
It should be connected to circuit breaker. Circuit breaker will automatically discontinue the flow of electricity if it detects faulty condition.
What do I do if there is no circuit breaker for outdoor light?
If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.
What size circuit breaker should be used for dishwasher and disposal?
A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.
A parallel circuit breaker should be connected in a parallel to the circuit it's protecting?
For a circuit breaker to protect anything, it must be wired in series with whatever it is protecting.
