A new 24-home "McMansion" subdivison is going up down the street from me. The homes start at $500,000.
The first one just went up (asking price $750,000) so I went in to check out the wiring. The cable runs are all very neat but upon closer inspection I found numerous violations.
-clamps broken off in multigang plastic boxes.
-18 cubic inch boxes with 3 12/2's in them.
-other over-filled 18 c.i. boxes (at least 10 of them)
-#14 used as "taps" for outlets on 20 amp circuits.
-Multiwire circuit neutrals not spliced (ie, outlet will splice the neutral once installed)
-Bath outlet tapped off dining room circuit.
-2 conductor cable used for travellers.
-orange wirenuts used to connect 3 or more #14's.
Other non-violations include no overhead lights in bedrooms (just a few switch controlled outlets) and everything else done to the bare minimum.
I compared the price on a case of 18 ci boxes to 22.5 and the difference is about $15 to $30 depending on the brand.
The sad part is the job passed inspection and they're insulating and sheetrocking now. The inspectors around here just don't care because crap like this passes all the time.
Oh well, I guess some things will never change.
