Well not being a liscensed electrician I wil comment on qualified person,Joe the pic you show unless someone knows who did the work and told you there is no sure way to know if person is qualifed or not just because a person is trained does not mean he willl always do work correctly.
Being a maint supervisor in several different plants there have been times that I have escorted lisc.elec. out of the plant and told them not to return because of basic sloppy work
On one occassion we hired a company to do a large remodel,every man a journey lisc. no way were my guys allowed to help do work ,well after finding ground wires not hooked up or under cover screw connections in EMT loose bushings cut and then stuck on pipe in boxes ,it made me wonder why with this sloppiness were they so concerned about my guys being unlisc.
Gentlemen please do not be so quick to say that a person that does sloppy work is unqualified it may be that he is qualified to do work but does not care what it looks like . I do agree that a lot of work is done by some one that is not qualified but not all,another thing is there may not be a choice if a man has kids home hungry and he needs his job he will do a lot of things that are not right
