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.
There are two different functions that run HSI to a furnaces. The two functions are Etymology and pacing.
The two phases of the Cell Cycle are:InterphaseMitosis
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
Full Moon and New Moon phases.
True.
furnaces in industries...
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.
Yes, using DPDT relays between the thermostat and the two furnaces.

A single-phase supply needs two wires to allow the current to circulate.
Law with Two Phases was created in 1984.
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
two phases of are waxing crescent and waxing gibbous
The phase voltage is usually constant and determined by the supply voltage.
Because the capacitor only needs to "excite" one of the two phases of the 230 volt supply in order to start the motor.
Catabolism and Anabolism are the two phases or Metabolism.
