If it's green it must be a ground, right?1712 viewsOne more example of grounding to gas, but with a twist... grounded to a non-conductive gas pipe. At least its on the low pressure side of the meter?! (just kidding).
|
|
Workmanship issues1704 viewsThis installation indicates workmanship issues as indicated by the loose wiring, but also improperly grounded to the light fixture adjacent.
|
|
A long, long pigtail ground1674 viewsAnother pigtail ground. This method of wire wrapping creates and electrical component called an inductor and reduces its performance as a ground wire.
|
|
Wrong Clamp - Wrong Time1660 viewsHere's an example of using the wrong type of ground clamp (not permitted outside) with the wrong size of wire (the #6 is too large for the clamp).
|
|
Common in mobile home communities1557 viewsThis installation utilizes an independent ground rod in violation of the NEC Section 820-40. Even if the ground rod were legal, this installation uses an improper clamp to make the connection.

This must be an interesting view.....1366 viewsMDU wiring run on the roof. At one time, the wiring was run up the side of the building in moulding, but the covers have come off and the wiring is now blocking the window. Wiring run on top of the roof is a violation of the NEC Section 820-10(d).
|
|
Multiple grounding connections on splitters1364 viewsIn this photo you will notice multiple ground wires attached to these splitters. One of the wires is simply wrapped around the top of the set screw. Also, the splitters are not mounted, nor is the ground wiring protected from flexing or damage. This is very typical of loose splitter situations.
|
|
Drop (Un)control box1353 viewsDrop Control Box?? From the picture it appears that a lock box has been removed and a new drop control box installed that contains a tap. It is not exactly controlling the drops. Workmanship issues and not grounded.
|
|
An inductive ground wire1333 viewsThis installation utilizes a pigtail ground to the electrical conduit next to it. The pigtail ground creates an inductor that reduces the effectiveness of the ground connection. Also, the particular conduit where the ground clamp is connected is not a permissable ground point.
|
|
It's a metal box, part of the power, Right???1287 viewsGrounded to an air conditioning cutoff switch. Ground wire not run properly or secured. Splitter not properly secured. Note the terminator on the input to the splitter. Another disconnect at the side of the house. Security issue.

|
|
Too close to power1251 viewsCable drop run too close to power. On this MDU with HUGE input electrical conductors, the installer chose to climb up into the wiring to secure the cable drop. NEC prphibits any connection within 12 inches of the power drop wires.
|
|
Another floodlight ground..1041 viewsFloodlight ground. Not the ground wire attached to the top light fixture with a standard copper ground strap. This is not an approved ground point.
|
|
MDU destruction1014 viewsA good example of what happens when someone breaks into a lock box and no one makes the effort to fix it. Held up by a couple of ty-wraps, this MDU box has seen end of life. Note the broken distribution cable at the bottom. PS...It's not grounded, either.
|
|
More workmanship issues967 viewsWorkmanship issues here. Loose wiring. Loose ground wiring. Devices not secured. On one hand they have used a drop control box for some of the wiring, but left the rest a tangled mess. Multiple NEC violations here. 820-40 and 820-6.

|
|
Cable drops across power conductors771 viewsMDU wiring. According to the building owner, this was "after" the upgrade, which was 'completed' in a single day. Wires run over the roof, even on top of the power drop conductors. Lock box has been broken into and wiring is a mess. Poor workmanship.
|
|
Wiring run too close to power759 viewsIn this photo you will observe the cable wire run directly under the main power conductors.

|
|
Grounded to Gas752 viewsGround wire attached to gas meter. Ground wire not protected. Violates NEC 820-40.
|
|
Just twist them all together. .749 viewsMultiple conductors on the same ground clamp. As indicated in the picture, multiple ground wires were twisted together and then clamped under a Fargo clamp. This connector is not rated for this kind of connection.

|
|
Drilled meter panel708 viewsIn this photo, the ground wire has been secured to the meter panel using a self drilling-self tapping sheet metal screw.

In addition, the ground wire was simply wrapped around the screw without benefit of a proper wire lug as required by the NEC.
|
|
Pigtail ground to the grounding electrode699 viewsIn this photo, the ground conductor has been coiled numerous times forming an electrical inductor. The NEC requires that the ground wire be run as straight as pratical and secured or protected to prevent damage.

|
|
Shared ground with power645 viewsIn this photo, rather than install a separate ground clamp as required by the NEC, the installer merely loosened the power ground and slipped his ground wire underneath the portion attached to the ground rod. This method is particuarly hazardous and not permitted under the NEC.
|
|
Two on a ground624 viewsIn this photo, the cable ground is being shared by multiple conductors. This type of clamp is rated for only one conductor and was already being used by the phone company .
|
|
