What size breaker do you use for a furnace?
It depends on the rating of the furnace. There should be a plate or sticker somewhere on the furnace that shows the rating. If you are just powering a blower motor the rating will be lower than if you have an electric heating element.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
Can you split hot water tank electric to stove?
No. Each circuit has to have its own dedicated circuit. The breaker and wire size differ between the two appliances.
What size of wire and breaker do you need for a 20kw electric furnace?
In order to properly size the wire per National Electric Code (NEC) standards you will need to know the amperage and the distance of the device (heater) from the source (circuit breaker panel). In order to know the amperage one would need to know the voltage since amperage changes inversely with voltage.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
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.
Installing a 120volt appliance what breaker is needed at the electric box?
Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.
Why do you need a 125 amp breaker for a 83 amp furnace?
If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.
What size amp circuit breaker should be used for a home entertainment system?
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
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 is the standard to select circuit breaker?
Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
Can I you use existing 8 3 wire hooked to a 30amp breaker was hooked to old electric heater to wire a heater that requires 10 2 wire its a 5000watt 240volt heater?
Yes the wire size is larger for that size breaker but will not effect the 30 amp breaker protection of that circuit.
