Well, I took the online prep exam Mike Holt offers, here's how I did:
After taking this test, I think I need to spend all the time I can reading 430 front to back and back to front, and make it my best friend. This article truly confuses me to no end. I could probably skate through and pass with a 70%, but I'd rather be comfortable before I get there and do it right.
If anybody wishes to discuss motor philosophy, this is an invitation to do so.
Thanks,
There were a few questions I got that I just flat had never heard of before, or did not comprehend the answers provided:Module 1. ? Practical Electrical Theory PART 1
Questions 1 - 25 of 100 ? You scored 21 of 25 ( 84% )
Questions 26 - 50 of 100 ? You scored 20 of 25 ( 80% )
Questions 51 - 75 of 100 ? You scored 19 of 25 ( 76% )
Questions 76 - 100 of 100 ? You scored 20 of 25 ( 80% )
Module 2. ? National Electrical Code PART 2
Questions 1- 25 of 100 ? You scored 23 of 25 ( 92% )
Questions 26 - 50 of 100 ? You scored 24 of 25 ( 96% )
Questions 51 - 75 of 100 ? You scored 25 of 25 ( 100% )
Questions 76 - 100 of 100 ? You scored 23 of 25 ( 92% )
Module 3. ? Journeyman Calculations PART 3
Questions 1 - 25 of 65 ? You scored 19 of 25 ( 76% )
Questions 26 - 50 of 65 ? You scored 18 of 25 ( 72% )
Questions 51 - 65 of 65 ? You scored 12 of 15 ( 80% )
Call me crazy, but once these loads are balanced, won't I see roughly 25 amps on each phase, or am I overthinking this? I guessed "D".The following information applies to Questions 45-49: Laundry circuit of 1,500 VA; two small-appliance circuits are 3,000 VA; 1/2 hp, 115V motor. Balance these loads on a 115/230V single-phase system, then answer the following question.
The total current of both Line 1 and Line 2 equals _____ amperes.
a. 30-35
b. 36-40
c. 41-45
d. 46-50
This one, and similar ones using the term "efficiency factor", completely threw me. I had no idea how to go about answering this question. So, how do you find this answer?Motors with a nameplate temperature rise rating not over 40?C must have the overload protection device sized at no more than _____% of motor nameplate current rating.
a. 100
b. 115
c. 125
d. 135
