In my quest to attain the ICC Residential Combination Inspector, today I sat for and passed the B1 & E1 exams. If anyone is interested let me know and we can discuss it on this thread. Hopefully in about 2-more weeks I will have completed the full series.
Had no trouble with the B1 test finished it with a 1/2-hour to spare. The E1 test was much harder then I expected (should have studied) if it wasn’t for may background and being able to answer about a 1/3 of the questions without looking them up I wouldn’t have had time to do the 20 or so really tough questions.
For instance, they gave you Volt-Amps & Voltage you had to size the circuit base on the Ampacity Table. They gave you Type, Number of Conductors in a Raceway & Ambient Temperature in Degrees F, you had to size the circuit breaker. I do not believe that someone without a good broad-based knowledge of both electric theory & code will be able to pass this test.
