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.

Can a 100 breaker box handle a 15 kw furnace?
The equation for amperage is I = W/E, Amps = Watts/Volts. The amperage for the furnace would be, Amps = 15000/240 = 62.5 amps. So to answer the question, yes a 100 amp breaker with a #4 copper conductor will be sufficient to operate a 15 kW furnace. A 70 amp breaker will work but it is cutting the edge a bit too fine as you don't need the furnace to trip off during the winter months (northern hemisphere) if you are away from your home for an extended period of time.
What is the difference between a 100 amp breaker box and a 125 breaker box?
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
What wire size do you need for a 125 amp panel with a 100 amp main breaker?
A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
If you have a 125 amp breaker box on the pole with a 125 amp breaker going to your house and you get a hot tub that needs a 60 amp GFI breaker would that overload the box?
It depends on what else you are running in the house. Add up your amperage to see if it is more than the 125amp rating. Which should be below 105 amps constant to keep from overheating the main breaker. If you are not running a big central ac system or a electric oven and water heater you should have no problem running the hot tub.
What size breaker do you need for a 40 gallon electric water heater?
Usually 30 amp
Does a water furnace use a 40 amp breaker?
Depends on the manufacture of the water furnace. Look at the data sheet or data plate on the furnace of contact the manufacture.

Can you hook up 200 amp dervice to a 125 amp service panel?
No. If device draws 200 amps breaker will trip.

The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
What Size breaker for 6 gauge wire?
You need a 60 amp breaker.

A #3 copper conductor with an insulation factor of 90 degrees C is rated at 115 amps. Even though the panel is rated at a higher amperage it is the main breaker that governs the wire size.
Need to move 2 breakers to a sharing breaker to add a 50 amp breaker need info on how to do this?
by doing your mum
What is type of breaker for 41 amp's?
50 amp breaker.
Can you put a 20amp water pump and a 30 amp water heater on a 50amp breaker?
No, they each need their own breaker of the right amp. Neither of them would cause the breaker to trip if there was a problem.
Is 15 amp breaker enough for a gas furnace?
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.
