Hello all,
First time reader, first time poster and long time telephone contractor here in the State of CT so please forgive me in advance for any errors in this forum.
What is a time accurate recommendation for book(s), reference materials or what have you for the C5 low voltage exam In CT? Specifically for the ambiguous questions that are only answered correctly if you know some one who knows. Yes I know, read the NEC 70 and 72 and other code books but I am referring to outdated questions still on the test that you only would come across on a state exam.
example: Q18 What is the typical maximum CCTV Coax length?
My response: Ahhh well umm, what resolution are the cameras? 300 lines? 800 Lines? 1920 x1080? Are you using RG11, RG6 RFG59 coax? Composite, S Video, RF modulated video? Are the camera's and monitors a manufactures 'set' that use equalization to compensate and extend for analogue signal loss over coaxial wire? How much loss is acceptable? Color or black and white?
Obviously this question is as outdated as the 1994 test question: What is the most common type of telephone wire?
[] Star Quad was the correct answer in 1994 - you know the 4 conductor Gr Rd Blk Yel phone cable used in the 60's and 70's. Star Quad Cable is nothing I have ever seen installed when working at the DPCP in Hartford and the only reason I got that right was my marine buddy was told that was the answer by a building inspector.
Thank you in advance for your thoughts. This is for both an apprentice under me and I am going to take advantage of the grandfathered T1 to C5 'license upgrade'
Be Well
PS does any body else find it rather organized that you can purchase the NEC 2011 as a downloadable PDF, the electrical exam is open book but you can't use a kindle or laptop or tablet at the test center? Who carries paper any more!
