Unless you want the power off or there is an overload condition that caused the breaker to trip.
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.
Yes. It should be a dedicated circuit from the distribution panel. There should also be an emergence shut off switch outside of the furnace area . This switch allows you to shut the furnace down from a remote area if a malfunction occurs at the 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.
You need a 60 amp breaker.
67,500 BTU electric 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.
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.
turn breaker off. unhook thermostat wire to furnace turn breaker on. worth a try; if it works you will have to turn off breaker to shut it down.
AWG #3 copper.
Unless you want the power off or there is an overload condition that caused the breaker to trip.
Depends on the manufacture of the water furnace. Look at the data sheet or data plate on the furnace of contact the manufacture.
Call an electrician; something in the furnace, possibly an electric motor, is using too much electricity.
The size of the furnace depends on the square footage of the house you are heating.
1200 foot propane furnace what size do i need
The electric furnace operates on 240 volts so a two pole breaker is needed.
Yes, a blown fuse can cause your furnace to not turn on. Check the breaker box and see if any of them have tripped.
