Hello All,
If the POCO available fault current is 65kAIC at POCO's 800A rated pullbox (208/120V, 3ph 4w) then what is the available fault current at the customer swbd which is 800A, 208/120V, 1ph 3w? POCO provide 3 phase service but the customer only uses 1 phase. The distance from the pullbox to the swbd is about 5ft.
A formula would be appreciated.
Thank you.
