FEEDER SIZING

[BillP]

HELLO I AM SIZING A FEEDER FOR AN APC UPS (40 KVA) SYMMETRA. BUT I NEED TO KNOW THE NEXT THING:
WHICH I UNDERSTAND THE UPS ELECTRICAL CONSUMPTION IS 40 KVA PLUS AN ADDITIONAL BECAUSE OF THE CHARGING BATTERIES PROCESS. WHAT IS THE AMOUNT OF THIS ADDITIONAL (BEST PRACTICE) ? 50% 30% ? = 40KVA + 40KVA?
WHAT OTHER FACTOR COULD INCREASE THE RATED UPS CAPACITY FOR THE SIZING OF THE UPS AND WHAT IS THE NUMBER?

THANK YOU

What model number Symmetra are you sizing for? The 40KW Symmetra PX's come in a few configurations which all require different feeder breakers. Is there a MBP PDU with this installation?

Thanks
