i missed my mqasters exam on the first try in june, by 7 points. i had just spent two days with ray holder in that class. i passed last week. i studied my arse off every day i had free time at work to do so. ( i work in an inspection office). math, brother, it's all in the math. give yourself time to get brushed up on it all. series circuits, parallel circuits, load calcs, generators, transformer ocpd, send me a pm, i'll try to send you some info. i used a ray holder and tom henry and mike holt books to prep for this. i gave myself time to study, and didn't schedule till i could DO the math in the alloted time. you wont pass just answering code questions. i'd say 25 % of that test is calculations, and 25% of those are series and parallel circuits. whe i got up from the computer, it said "pass", they gave me the score outside on a sheet that showed strengths and weaknesses.
they throw some weird stuff at you, like this one,(not exact memory, but you'll get the idea) 8 construction trailers, 720 sg. ft. each, 18 receptacles each, 10- 1500 watt, 3 lamp flouresecent fixtures, with a .95 amp ballast, each trailer has 2 outside air conditioners that are rated at 6500 watts, and they each have a HID security lamp at each trailer that is rated at 3200 watts. 120/240 volt service. what minimum size 75 degree thhn service conductor is needed for the service that supplies all these trailers and and what is the maximum size ocpd permitted on this service.
the trick to any test is taking each question apart and fiqure out what the &*&* they are asking, and then go from there.
tab your book, highlight your index, make notes in your book in ink, they will let you in, i just did it
