If i were to connect 200a of load on each leg to neutral (120v) i would be pulling 72,000 va. 270w x 160 fixtures = 43,200w. 208v * 200a * 1.732 sqrt (3) gives me about 72,000 va theoretical power output of the service.
270w x 160 fixtures = 43,200w. 28/03/2011 · this panel schedule calculates either 1 or 3 phase, there is an if function that calculates based on the phase type entry at the top of the spreadsheet (again 1 or 3). 43,200 w / ( 208v * 1.73 ) = 120a @ 208v 3 phase. If you have 30 of them, total load on the panel is 956.8·30 = 28704 va or 9568 va per phase. Multiply the sum from step 3 by 0.8.
Using above mentioned formula anyone can do three phase load.
By multiplying by 0.8, you are correcting for this safety feature. Multiply the sum from step 3 by 0.8. Your 200a panel should work fine. Single & three phase line kva calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection. If you have 30 of them, total load on the panel is 956.8·30 = 28704 va or 9568 va per phase. 01/03/2009 · as an example, consider a balanced three phase load consuming 36 kw at a power factor of 0.86 and line to line voltage of 400 v (v ll) : The phase balances reveal using va rather than amperes. Information required for electrical plan check inspecting tandem circuit breakers structure tech home inspections panel board load calculation mike holt s forum understanding the basics of delta transformer calculations ec m difference between three phase and single power voltage drop calculator 3 ac. For three phase system we use following 3 phase power calculation formula. 2.25a x 120v = 270w each.
