This is because furnaces are an enormous electrical load! The electric furnace for my 3 bedroom apartment is on a 60A 240V breaker. That means that for a medium sized apartment the furnace can use up to 14.4kW. Wow! Because the power draw is so high, the heater element runs at 240V instead of 120V. To draw that much power off 120V, the circuit would have to be rated to 120A. That is an enormous circuit, and is possibly enough to blow a main breaker if enough other appliances are on. By doubling the voltage a load you can halve the amount of current it draws. This allows for lighter wire, smaller control hardware, and is "healthier" for the house's electrical system.
What else can I help you with?
What two function do some HSI' perform and a furnaces?
There are two different functions that run HSI to a furnaces. The two functions are Etymology and pacing.
What are the main 2 phases of the cell cycle?
The two phases of the Cell Cycle are:InterphaseMitosis
What are the phases of respiration?
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
When are two phases at equilibrium?
Two phases are at equilibrium when the rate of their interconversion is equal in both directions. This means that the amount of substance transitioning from one phase to another is the same in both directions, resulting in a stable balance between the phases.
How 240 VAC achieved in a 120 VAC environment North America home?
By connecting two separate 120 VAC legs into one. If they are and if it comes to your home from a local utility they will be, it will add to 240. Whenever combining AC or Sine waves into one for the purpose of adding they must be in phase.
What are the uses of two phase supply?
furnaces in industries...
Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
Can you wire two furnaces to one thermostat?
Yes, using DPDT relays between the thermostat and the two furnaces.
What two function do some HSI' perform and a furnaces?
There are two different functions that run HSI to a furnaces. The two functions are Etymology and pacing.
Is a 220 volt single phase in the US two single phases of the same sine wave?
A single-phase supply needs two wires to allow the current to circulate.
When was Law with Two Phases created?
Law with Two Phases was created in 1984.
How do you connect a 230volt 60Hz air conditioning unit with one phase wire to a 240 volt 60Hz two phase south American supply?
Treat the USA 2 Phases as 1, its called split phase, instead of Line and Neutral, you ahve two phases but they deliver 240v, this will not hurt a 230v machine as the chances are that you are NOT getting 240v supply at the delivery point anyway. As long as the machine si 60Hz and supply 60Hz, you will not have a problem
Why does a 230volt motor have a 110 volt capacitor?
Because the capacitor only needs to "excite" one of the two phases of the 230 volt supply in order to start the motor.
What is the phase voltage inside a motor if one phase is lost and what is the voltage between the other two phases?
The phase voltage is usually constant and determined by the supply voltage.
What are two names of the two phases of the heartbeat?
The two phases of the heartbeat are systole (contraction phase) and diastole (relaxation phase).
Metabolism can be categorized in what phases?

What phases can metabolism be categorized?
Catabolism and Anabolism are the two phases or Metabolism.
