Gentlemen, Here is a problem that seem to happen and keeps happening more and more . Sorry for repeating my self. I have a 400amp 480/277v distribution panel serving each office floor. each floor has approx. 54,000sf. The tenant moves in and takes up 37,000 sq. ft. and at 7 watt per sq. ft. he is entitle to 265amps. However because he as a small data center with redunant UPS and CRAC units they require in the 400A panel (2) 150A, (2) 50
A, (1)175A for XFMR ,100A for Lighting and 40A for TVSs all 3pole.
Now this is the issue. There is still 17,000 sq. ft for the next tenant remaining. The 400A panel is total out with all the breakers install. 9 month after the tenant has moved in, the next tenant is looking for 225A. Where do we get it from. Checking the load meter for the existing tenant his highest peak for the year including Summer loads was no higher than 3 Watt per sq. ft. Do I tap into the same 400A panel . Tha existing tenant has not even come close to using his power potential
This is happening in many facility where consulting engineers require all this power only to see them actually use a fraction of the load and costing the owner more ether in bring in a new riser or modifying the existing serve.
