Includes motor calculation steps, box fill, ranges, transformers, conduit fill, PIE, EIR, and more!

If your testing center allows short notes in the code book, write these formulas down. This way you don’t have to try to remember them during the test.

Check your test provider’s website to see if they allow short notes in the book.

For those who are not allowed to have written notes in the book, make yourself some flash cards and memorize these formulas.
