Hi. I'm making a 3 phase furnace with heating coils. Total power rating is 5 KW. I have to make one heating element for each phase. How do I split the KW rating? Will it be a straight 5/3? Also when calculating the resistance for each heater, should I calculate based on 220V(single phase voltage in India) or 440V (3 phase voltage)?

Are the elements connected in star or delta configuration?
So each heating coil will be subjected to 440V across 2 phases, yes?
Delta Connection (Δ): 3 Phase Power, Voltage & Current Values
What is Delta Connection (Δ)?Delta or Mesh Connection (Δ) System is also known as Three Phase Three Wire System (3-Phase 3 Wire) Voltage, Current & Power Values in 3-Phase Delta Connection. Line Voltages , Phase Voltages, Line Currents & Phase Currents & Power in Delta (Δ) Connection.

you must firstestablish whatvoltage teach coil requires.if it's 230V per coil, then 415V is :

In delta each coil would be 5000/3 = 1666watts.So res of coil would be v squared/watts = 440sq/1666=116ohms per coil.If you say the single phase v is 220,3 phase should be 380v not 440v,unless its a wierd system.

Use vehicle generation system to charge leisure batteries, replace with B2B charger retaining the existing wiring, or replace everything?You should be able to get a good size 110v battery charger off the shelf.
