storage building

[unwell_1207]

i was asked to design a storage building. i have 28-68.5W fluorescent lamp, and need to provide 4-13A socket outlets 400V 3phase and 19-13A socket outlets 220V. The storage building has an area of 222sq.meter.Can someone help me in the load calculation and how to size my circuit breaker? and also can i ask what is ampere trip and ampere frame? Thanks in advance.

my calculation goes like this:

28 x 68.5 = 1918 w, 1918/230=8.34A

4x13A x 400v = 20 800 w; 4x13a=52A (Im not sure)

19x13A x 230V= 56 810w; 19x13A=247 (Im not sure)


total load= 79528W

total current= 307.34A

Am i correct?

based on your criteria I am guessing your installation does not fall under the NEC.

making an NEC load calculation for such an installation would therefore be meaningless.
