Re: range calculations
Jim, just so you know, I'm not trying to give you a hard time.
Note 1 of table 220.19 says the maximum demand will be increased 5% for each additional kilowat of rating or major fraction thereof by which the rating of the individual ranges exceeds 12 KW. With this wording, the .4 being less than a major fraction could be dropped.
With this being the case, column C gives you the KW rating, not a percentage, so you would read across the quantity of 5 ranges line and see 20 KW as the answer.

Re: range calculations
ok, then roger what is considered a major fraction? If .4 kilowatts is not a major fraction what would be considered a major fraction 1/2 kilowatt .5. What's the cut off?i don't understand this. So what your saying is disregard the .4 all together. can someone clarify this for me please?regards jim

Re: range calculations
Jim, "major fraction" is more than .5 (1/2)in any math.
You will see in Chapter 9 note (7) that a specific fraction of .8 is specificaly writen for that application, but for this thread .5 is the cut off.
Maybe someone else will solidify this for you.
