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.
|
|
A double gas meter ground954 viewsGround to gas. Look between the meters. Green ground wire extends from cable wiring under the house craw hole to a ground clamp attached to the gas supply pipe in the middle. NOT an approved ground connection. .

|
|
An easy way to break the ground wire...655 views...just put it on the flip up lid of the breaker box. Then just wait for it to break.
|
|
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.
|
|
And now in living color....910 viewsYes, the building is this color (purple/pink?). Ground wire was not secured. Paint was not scraped prior to installation of the clamp over the spray stucco coating.
|

Another floodlight ground, MDU542 viewsMDU ground to a flood light fixture. The MDU rebuild crew decided that a floodlight over a carport on this MDU was a suitable place to run the ground wire. Note the copper ground strap wrapped around the painted electrical conduit.
|
|
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.
|
|

|
|
Are we chillin yet?569 viewsIn this photo, the ground wire has been connected to a screw on the base of a residential exterior air conditioning unit. Hardly a proper ground in the eyes of the National Electrical Code. Easy to do? Yes. Correct? NO. Lazy? You bet!
|
|
Breaker box panel screw687 viewsGround to the center lid screw on a circuit breaker panel. Not an approved ground connection as it interferes with the opening or maintenance of the breaker panel.
|
|
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.

|
|
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.
|

|
|
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. This type of installation is hazardous as the installer drilled directly into the wiring area of the circuit breaker portion of the panel. In addition, the ground wire was simply wrapped around the screw without benefit of a proper wire lug as required by the NEC.
|
|
Drilled meter panel564 viewsIn this photo, the ground wire is secured to the bottom of the meter panel with a self tapping sheet metal screw. The ground wire is wrapped around the screw rather than properly secured in an appropriate wire lug.
|
|
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.

|
Good neutral bond, but not legal. Dangerous too!!1278 viewsIn this case, the installer ran a ground wire into the main electrical panel and installed a wire clamp on the utility neutral conductor.
|
|
Ground connection to hinged panel door442 viewsIn this photo, the ground wire is connected to a screw on the hinged portion of the breaker panel door. This connection is not suitable because it requires the cable to flex when the door is opened. In addition, the hinge is not a solid ground connection due to the fact that it is moveable. Moreover, the wire is not secured by a suitable clamp at the screw.
|
|
Ground not run as straight as practicable721 viewsNotice how the ground wire is run as straight as possible, but not as straight as practical.
|
|

|
|
Grounded to the P-hook (Part 2)605 viewsIn this photo, you see a close-up of the ground conductor wrapped around the p-hook screwed into the side of the building. This is not a legal ground. It is, however, an example of poor workmanship and NEC non-compliance.

|
Improper piggyback ground to telephone protector586 viewsIn this photo, the cable installation was grounded by running the green ground wire from the cable ground block into the adjacent telephone box and grounding it to the telephone protector block. This is sharing a ground and tampering with telephone facilities. Not permitted under the NEC.
|
|
Inadequate size ground wire for MDU installation439 viewsThis multiple dwelling unit is wired using .500 hard line cable. The lockbox and connections are provided with only a #14 ground wire. The NEC calls for a ground conductor equal to the current capacity of the hardline shield, up to a #6 conductor.

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.
|
|
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.
|
|
