Calculate total watts on three phase
WebNov 5, 2008 · iwire said: I agree with Roger but suggest you think in terms of watts not amps. A 200 amp 120/240 service can provide 48,000 watts of power. 240 * 200 = 48,000. A 200 amp 208Y/120 service can provide 71,968 watts of power. 208 * 200 * 1.73 = 71,968. I would go a step further and not use the term "watts" at all, but rather use volt-amperes. WebNov 12, 2013 · Lets say I have a 208V 3-phase heater (delta connection), with a heating element on each leg L1, L2, L3. 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.
