Re: WI Master exam
One aspect of the Wisconsin exam that you should be especially prepared for is providing the correct code reference/s for your answer. Some answers may only require one code reference while others may require two or three code references. For instance, a question might ask to size the main bonding jumper and the answer might require citing 250.66 and 250.28 also because 250.28 (D) states, "The main bonding jumper shall not be smaller than the sizes shown in Table 250.66."
The point is that citing all the required references is very important on the Wisconsin exam, so you need to be able to relate the different code references.
I hope this will help you in your preparation and good luck on your exam.
