How many amps in each leg of a 15kW heater?
The total KW of the heater is 15 KW. My calculation for amps in each leg is 15KW*1000/ [208V*1.73] = 41.7 amps. On each leg there is a thermal limit switch with 25 amp rating. Since I1 = I2 = I3 = 41.7 amps in each leg, I need to split into two branches to divide the amps into two because of the 25 amp limit switch.
How many amps does a 10kW heater pull?
Besides, how many amps does a 10kw heater pull? 10,000 watts divided by 240 is 41.6 amps. This is a "continuous load" so the wires must have an ampacity of 125% of 41.6 amps, which is 52 amps. Similarly, how do I know what AMP my heater is?

How do I know what amp my heater is?
Divide the wattage by the voltage to determine the current drawn by the heater. This works because watts divided by voltage equals current. For example, if the wattage is 2,000 watts and the household voltage is a nominal 120 volts, divide 2,000 by 120 to determine the current.
DC kilowatts to amps calculation
The current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the voltage V in volts (V):
AC single phase kilowatts to amps calculation
The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the power factor PF times the RMS voltage V in volts (V):
AC three phase kilowatts to amps calculation
The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V):
How many amps does a tankless water heater use?

Q. Is 200 Amp Service Enough For Tankless Water Heater?
They need at least 120 amps to function properly, and the capacity of an older house is 200 amps. So, it is essential to upgrade the electrical system to support the hefty load demand, which could cost approximately $1500.
Q. Do Instant Water Heaters Need A Dedicated Breaker?
Yes, you will have to add 3 circuit breakers to the interior panel and pull three new circuits. Many residences don’t have 3 open spaces in the panel to make the heater installation possible.
Q. Do Electric Water Heaters Require 220 Volts?
Many electric units work on 220 to 250 volts. This voltage needs a double circuit breaker evaluated for the amp draw of the devices.
