Hi I recently took the journeymans for Mn and had a question I was wondering if I did it right. Can you guys help?
Question was: You have a 2 story building and its 28*40. How many 15 amp circuit can you put on the building?
answers where: 2, 3, 4, 5, 6
1st)What I did was 28 * 40 * 2( because two stories)=2240 sq ft.
2nd) 2240sq ft * 3va (came off tables in 220) = 6720 va
3rd) 6720va / 240v = 28 amps
4th) 28 amps / 15amps = 1.8 circuits so meaning two 15 amps circuits.
What Im having the issue is, On the third step, Do I divide that by 240v the higher voltage or 120v? Can someone help me if I did this right or not!
