Administrator test Voltage to use

[tony3phase]

Would anyone happen to know if load calculations for motors on Washington state administrator exam are based on nominal voltages 120/240 480 or are they based on 115/230 460 as listed in tables in code book. just doing a practice question with a 3/4 hp pool pump and 5 hp AC unit it means the difference between a 110a service and a 125a service and I have noticed it being done both ways in practice questions.
And yes using Mike Holt exam prep book
Thanks any help would be greatly appreciated

The code states:
220.5 Calculations.
(A) Voltages. Unless other voltages are specified, for purposes
of calculating branch-circuit and feeder loads, nominal
system voltages of 120, 120/240, 208Y/120, 240, 347,
480Y/277, 480, 600Y/347, and 600 volts shall be used.
I don't see any other requirement in 430.

I would use 480V on the administrator just to make sure.

Yes took test today and they call out voltage on questions and they are using nominal. On majority of questions I could not get exact number as far as volt amp or total amperage, I think it is a matter of interpretation, like weather sign power 1200va is considered continues or not and so on.
I just want to say thank you Mike Holt and staff your book Electrical exam preparation is the best money I have spent in this whole proses.

Look out Washington there is another Administrator in the house.
