1.) Branch-circuit equipment grounding conductors that are not spliced or joined together with in a box.
2.) A grounding electrode conductor that is attached to the grounded conductor or equipment grounding terminal bar of a remote panelboard.
3.) The non-use of expansion fittings on conduits emerging from the earth that are attached to fixed equipment and are installed in locations that are subject to ground movement.
4.) The non-use of expansion fittings in Rigid Non-Metallic (PVC) conduits that are subject to thermal expansion and contraction.
5.) The improper securing of expansion fittings in runs of Rigid Non-Metallic (PVC) Conduit.
6.) The improper supporting of Rigid Non-Metallic (PVC) raceways.
7.) The Improper installation of cord connected electric-discharge light fixtures.
8.) The improper supporting and securing of branch-circuit wiring methods, located above suspended ceilings, that supply light fixtures or equipment.
9.) The non-bonding of metal raceways containing grounding electrode conductors. This problem is more common in dwelling unit installations than with commercial or industrial installations.
10.) The non-bonding of service raceways and equipment.
11.) The improper conductor fill of conduit bodies.
12.) The lack of "in use" type covers on outdoor receptacles.
13.) The non-use of a locking type disconnect for submersible well pump motors.
14.) The improper bonding and grounding of transformers.
15.) The lack of verification of the available short circuit current at the supply terminals of service equipment.
16.) The improper supply for emergency unit equipment.
17.) The mixing of emergency (Article 700) system wiring with legally required (Article 701) and optional (Article 702) system wiring.
18.) The improper installation of ground rods.
19.) The improper connection of septic pumps.
20.) The supporting of cable or other raceways from raceways.
21.) Use of electrical equipment without following the manufacturers installation instructions.

Excavtors do much septic installs here, i've 'had it out' with many over the pedestal deal.
I won't dig, if they won't wire......

19.) The improper connection of septic pumps.

There are several different problems that can stem from septic pump installations. First, Section 430-102 (a) requires the installation of a disconnecting means in sight from a motor controller location that disconnects the controller. In the case of the typical residential septic pump installation the controller would be the float switch in the pump tank. Section 430-102 (b) requires a disconnecting means in sight from a motor location to disconnect the motor. Unlike the well pump scenario above the motor and controller are located in the same location so the exception to 430-102 (b) which allows you to eliminate the motor disconnect if the controller disconnect is capable of being locked in the open position won't do any good in this case.
Article 100 defines "in sight from" to be visible and within 50'. So there should be a disconnecting means that is visible and located no more than 50' from the pump tank. In most cases the pump and controller (float switch) are inserted into a receptacle located near the tank so the attachment cap for the controller and pump cord can serve as the disconnecting means. Note in the sentence above that the disconnect must be visible.

Most often the homeowner does not want to see a pedestal with a receptacle and cords so the attachment caps are cut off and the cords are wired directly (hard wired) into a junction box that is located in the tank. If the pump and controller have been hard wired many times there is no disconnect at all located within site from the motor or controller.

In many cases the receptacle has been installed inside the pump tank. Before making this kind of installation consideration should be given the issues of accessibility and corrosion. Also depending on the size of the system there may be sufficient enough hazardous vapors in the pump chamber to classify the location. The classified locations are more common in commercial and industrial applications.
