I think the answer to a question about fixture counts and dFu values references the wrong code. “Per IBC Table 709.1” might need to be revised to “Per IPC table Table 709.1”.
Welcome to the Black Spectacles Community @kylelyamada1000 and thanks for checking out Real-World Practice! Great catch and yes, those should have said ‘IPC’ in reference to the International Plumbing Code. I have fixed those answer explanations. Sorry for the confusion!

@dbollen Thanks for writing in! It appears that there was a small typo in the answer explanation for the Question 6 equation, which is probably what was causing confusion. I’ve fixed it, so please take a look at the answer explanation again. So sorry about that!
Essentially, you are taking the electrical equation Watts = Volts x Amperes x Power Factor and converting it to an equation that solves for the minimum circuit size (amps): Amperes = (Watts) / (Volts x Power Factor). Then, you plug in the values you’ve been given and determined.
Let me know if you have any further questions!
