What this subtopic covers
Ground-fault circuit interrupter protection provided in all required locations.
How to drill it
- Find the chapter of the International Residential Code that carries this subject and read it once for structure, not retention: what lives here, what gets sent elsewhere, which tables exist.
- Write your own plain-language phrases for what this subtopic covers, then note the code's terms beside them. Mismatches between the two columns are exactly where exam questions cost you time.
- Run timed lookups: pick a requirement named in the descriptor above, start a stopwatch, find the governing text in your book, stop. Log the seconds. Past two minutes is a miss even when the answer is right.
- Weight your reps to the number above. Roughly 2 to 3 questions means this subtopic deserves repeated timed reps inside its area session.
