Service Calcs Industrial

[brother]

Looking at the calculations for industrial example in the code book. Example D3(a) where do they get the '25%' from on largest motor and the 25% of 56,600 VA ?? I see where it has to 125% but just 25%??

Any number plus 25% of that number is the exact same thing as 125% of that number. For example:

500 + 25% of 500 = 625

500 x 125% = 625

What may bite you in the behind sometimes is that 500 is 80% of 625, not 75%. 1/125% = 80%

Another one is that 25% of 625 is 156.25, NOT the 125 that you added to the 500 when you multiplied by 125%.
