I am studying for a journeyman test and am having a hard time finding these questions and will appreciate any help with these including the article number and reasoning behind this questioning.
1) Requirements for equipment-grounding conductors include all of the following, except:
A)They must be without splices
B)They must not carry objectionable current
C)They must be mechanically connected if spliced
D)They must all connect when entering the same box
(I beleive this to be an oldie but goodie. I have searched all of Art. 250 for the answer. I think this was at one time word per word in the code and at some point was omitted)
2) Where liqidtight metal conduit is installed outdoors, above grade, the interior of this raceway is considered to be in a _____ location.
A)dry
B)wet
C)damp
D)raintight
(According to the definitions, I beleive it is dry but not sure)
3) Given: A single-family dwelling has a main breaker rated at 200 amperes. The calculated load is 100 amperes.
What is the minimum size AWG THWN copper conductor permitted for the service entrance conductors to this dwelling?
A)4
B)1/O
C)2/O
D)3/O
Thanks in advanced for your help on these.
