I just went and took a master exam today. I am trying to remember some of the questions that I was unclear on, but I cannot remember them verbatim. A couple that stick out right now are as follows:
1) How much dedicated electrical space (I think that was the phrase) must exist above a 1200A rated service switch operating under 600V. Is this 6' ?
2) Power conversion as it relates to adjustable speed motors (or drives, can't remember the exact wording) is referring to/concerning 1) harmonics 2) amps 3) frequency 4) voltage. I think it is voltage or frequency, but I cannot narrow it down.
3) What is the rating of a pre-wired modular surface mounted raceway? 1) 600V 15A 2) 600V 20A 3) 300V 15A 4) 300V 20A
4) In what case does a receptacle in a closet not require AFCI protection? I don't remember all the possible answers but there were two about fire alarms and one about a security alarm panel
5) What is the maximum length of a unprotected (indoor) feeder tap? I chose 10'
I wish I could remember these more clearly, but my head is still whirling from the 103 questions in 5 hours. I got a 72, close but no cigar... :slaphead:
