What about #1-- you certainly can splice an egc. I see #4 as a possibility but egads this is a bad question.
Thank you for all your replies, I looked in article 300 as suggested by you fine gentlemen, an found the answer to question number three.
Article 300.9 Raceways in Wet Locations Above Grade.
Answer B) Wet
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
250.6 eliminates B
250.148 (A) and (C) eliminates C and D
I might miss #1, but I would think the answer is "D" as that is not always a true statement. Conductors passing thru a box need not be connected.
