More Code catastrophes
As usual, never consider the following commentary associated with these photos as a formal interpretation of the National Electrical Code (NEC). Without criticizing anyone or any product, the following scenarios present us with serious safety questions.
All references are based on the 2005 NEC.
I found this shoddy installation in a shopping center parking lot in Wichita, Kan. Notice how the installer tapped the conductors at the light pole to serve equipment that was located under a handhole cover, which is housed in this battered corrugated metal enclosure.
As you can see in the close-up photo, this electrical metallic tubing (EMT) isn't doing a good job of protecting the conductors running through it. Considering the open raceway and exposed wires, this scenario is an accident waiting to happen — especially after dark.
As per 358.12, EMT cannot be used where, during installation or afterward, it will be subject to severe physical damage.
LACK OF PROTECTION
This installation was discovered during a kitchen remodel rough inspection in an apartment building. As per 300.4(B)(1), “In both exposed and concealed locations where nonmetallic-sheathed cables pass through either factory or field punched, cut, or drilled slots or holes in metal members, the cable shall be protected by listed bushings or listed grommets covering all metal edges that are securely fastened in the opening prior to installation of the cable.”
Clearly, the so-called bushing in the right side of this photo does not meet this requirement.
