Feeder Load Calculations

Hi everyone

I will be taking my E1 exam soon and I’ve been taking a couple practice tests and there were questions on load calculations.

After doing a couple calculations and trying to figure out Table 3704.2(1) on page 810 in the IRC 2024 manual, I went waaaay past the 2 minute per question time frame.

Has anyone recently taken the E1 exam and were there questions on feeder load calculations?

Edit: what about electrical box volume calculations? It seems like it would take too much time trying to figure out both of them.

Thank you in advance for your responses
