OK. You need to calculate. Is there a question? We are not going to do the calculation for you. Have you tried to do the calculation, and have you run into questions or problems? Tell us what you have done, and then perhaps we can help.

690sf * 3va = 2070va
2070va/120v=17amp or (2) 15a cir
small appl=(2) 1500=3000
-------
5070va
3000@100%=3000

2070 @35%= 325
------
3325va/(208v)(1.732)=total load ? 10amp per unit * 16 = 160amp

What's the question?

 

[petersonra]

690sf * 3va = 2070va
2070va/120v=17amp or (2) 15a cir
small appl=(2) 1500=3000
-------
5070va
3000@100%=3000

2070 @35%= 325
------
3325va/(208v)(1.732)=total load ? 10amp per unit * 16 = 160amp

does this pass the smell test?

I would suggest you read up on how to do a calculation. Then post a specific question or two.
Thanks
