Wrong Clamp - Wrong Time1630 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).
|
|
If it's green it must be a ground, right?1681 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).
|
|
Ground to an electric conduit1520 viewsGround to an air conditioner conduit. Ground wire not properly secured. Not an approved ground point.
|
|
Common in mobile home communities1528 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.
|
|
A long, long pigtail ground1642 viewsAnother pigtail ground. This method of wire wrapping creates and electrical component called an inductor and reduces its performance as a ground wire.
|
|
An inductive ground wire1306 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.
|
|
Workmanship issues1680 viewsThis installation indicates workmanship issues as indicated by the loose wiring, but also improperly grounded to the light fixture adjacent.
|
|
No security here...1349 viewsMDU wiring. Workmanship issues here as well as secutity and NEC. Lockbox lid is missing. Wiring is hanging out. Not grounded and too close to power.
|
|
Too close to power1233 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.
|
|
This must be an interesting view.....1346 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).
|
|
It's a metal box, part of the power, Right???1264 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.

|
Distribution cable ground933 viewsDistribution cable grounded by installing a copper ground strap around the shield and tightening the set screw, damaging the shield.
|
|
More workmanship issues953 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.
|
|
Coiled ground not secured897 viewsPigtail ground. This ground wire was coiled many times and as a result, it is not run as straight as possible and as an Inductor, inhibits the ground capability.
|
|
If is is metal, it must be a ground...901 viewsGround to air conditioner cabinet. The installer grounded the cable to a screw located on the back of the window air conditioner.
|
|
'Grounded' to gas locate wire!?!1256 viewsA novel ground connection. In this photo, look for the orange locator wire next to the gas regulator. Cable installer has spliced the building ground conductor to the gas company locate wire that runs with the plastic underground gas pipe.
|
|
A double gas meter ground942 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. .
|
|
More grounded to the gas meter817 viewsGround to Gas.
|
|
And now in living color....894 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.
|
|
Drop (Un)control box1333 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.
|
|
Top flange of disconnect box851 viewsGrounded to the top of a power disconnect box. Ground wire is simply wrapped around a loosened screw on the top flange of a power box.
|
|
Any screw will do798 viewsGround connection to a panel lock. This poor ground connection was made by passing the ground conductor through a hole in a security sleeve installed by the power company on a meter panel.
|
|
Secure it to the electric panel fastener774 viewsCloseup of a ground connection made using a lug to the panel screw holding the safety panel inside of a breaker panel. Note the exposed conductor rubbing against the bottom of the breaker box. Not an approved connection or connection point.
|
|
A wonderful ground to gas768 viewsGrounded to Gas. One of our favorites. NOT an approved NEC ground connection.
|
|
MDU destruction1002 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.
|
|
Breaker box panel screw677 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.
|
|
Right through the middle of power805 viewsCable hard line construction right through the middle of power lines. This .500 cable drop is installed literally in the middle of the power conductors on the MDU.
|
|
Good neutral bond, but not legal. Dangerous too!!1259 viewsIn this case, the installer ran a ground wire into the main electrical panel and installed a wire clamp on the utility neutral conductor.
|
|
Into the panel we go...781 viewsMultiple NEC violations. First the wire is routed over the lip of the power conductor access and then screwed to the panel. Not an approved ground connection.
|
|
Just twist them all together. .742 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.
|
|
To the meter panel screw again.694 viewsGrounded to the center screw on a power panel. This connection interferes with access to the meter panel.
|
|
Rusty ground connection661 viewsGround strap on a very rusty power weatherhead. The installer had to work his way through the power conductors to make this very poor connection to an extremely rusted power mast. No apparent effort to clean or prepare the grounding surface. Too close to power conductors.
|
|
A messy MDU716 viewsMDU wiring and security. On this building, the lock box has been abandoned and wiring left exposed on the outside of the building including filters and splitters. Very poor workmanship and security.
|
|
Another floodlight ground, MDU537 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.
|
|
Cable drops across power conductors767 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.
|
|
Up 'n Over!652 viewsMDU wiring run on top of the roof. The lockbox is unsecured and not grounded. Many workmanship issues here.
|
|
Weatherhead danger...815 viewsGround strap installed in the middle of power conductors. This is a dangerous situation for the installer.
|
|
CATV lock box grounded to a flood light595 viewsIn this enlightening situation, you see the ground wire attached to a clamp mounted on an electrical conduit feeding a flood light at the rear of an apartment building. This is not a permissable ground point.
|
|
Wiring run too close to power753 viewsIn this photo you will observe the cable wire run directly under the main power conductors. The NEC prohibits any run of wiring to come within 12 inches of the power cables prior to the weatherhead. In this case, the installer had to pass the cable between the conductors.
|
|
Multiple grounding connections on splitters1354 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.
|
|
Ground to Air Conditioner Cutoff switch585 viewsHere's a grounding bar installed on the remote cutoff switch for an exterior air conditioner unit. The NEC permits grounding ONLY to the meter panel itself, not a remote switch or metal enclosure.
|
|
An easy way to break the ground wire...646 views...just put it on the flip up lid of the breaker box. Then just wait for it to break.
|
|
Are we chillin yet?562 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!
|
|
Pigtail ground to the grounding electrode693 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.
|
|
Drilled meter panel558 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.
|
|
Drilled meter panel701 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.
|
|
meter clamp ground568 viewsIn this photo, multiple ground wires are pinched in the cable clamp on the bottom of the meter panel. Inserting the ground wire in the cable clamp is not an approved method.
|
|
Meter flange ground (Part 2)589 viewsClose-up photo of ground wire attached to a flange screw on top of the power meter panel.
|
|
Meter flange ground (Part 1)593 viewsIn this photo, the unsecured ground wire is grounded by loosening one of the top conduit flange screws and wrapping the ground wire around it. . See the close-up in the next photo.
|
|
Grounded to the P-hook (Part 2)600 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.
|
|
Grounded to the P-hook ( Part 1)484 viewsIn this unusual photo, the ground wire is seen rising vertically towards the p-hook. In the next photo, you can see the conductor wrapped around the P-hook with the intention of being a ground point. No-go!
|
|
Spliced ground connections686 viewsIn this photo, multiple grounds are spliced into another ground wire using a "Western Union" type of splice and black tape. Not an approved form of connection.
|
|
Multiple grounds on a clamp608 viewsThere are multiple ground wires on a ground strap designed to only secure one wire. In addition, the ground wires are not secured to the building to prevent damage or breakage.
|
|
Improper ground attachment604 viewsThe ground wire is pinched in the cable clamp of the power service to produce a panel connection. Nice try, but not to code.
|
|
Ground not run as straight as practicable710 viewsNotice how the ground wire is run as straight as possible, but not as straight as practical.
|
|
Crush a ground # 3615 viewsIn this photo, the ground wire is crushed under the lid of the power panel. The NEC prohibits this kind of wire routing becuase it does not protect the ground wire from physical damage.
|
|
Crush a ground V2.0502 viewsNotice the grounding conductor pinched between the wall surface and the cover lid. In addition, another conductor is passing through the screw hole in the plate in an unprotected manner.
|
|
Multiple conductors on a lug rated for one563 viewsHere's a grounding lug improperly mounted on the mast flange of a power panel. In addition to improper mounting of the lug, there are multiple conductors inserted into the lug.
