'Ground' to an HVAC return line?!741 viewsThis is a classic! Ground wire not stripped. Clamp loose. Clamp attached to a refrigeration return line (not a grounded point).
|
|
If is is metal, it must be a ground...919 viewsGround to air conditioner cabinet. The installer grounded the cable to a screw located on the back of the window air conditioner.
|
|
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).
|
|
'Grounded' to gas locate wire!?!1275 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 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. .
|
|
More grounded to the gas meter828 viewsGround to Gas.
|
|
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.
|
|
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.
|
|
Top flange of disconnect box860 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 do810 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 fastener785 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 gas778 viewsGrounded to Gas. One of our favorites. NOT an approved NEC ground 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.
|
|
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.
|
|
Right through the middle of power816 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!!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.
|
|
Into the panel we go...790 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. .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.
|
|
To the meter panel screw again.698 viewsGrounded to the center screw on a power panel. This connection interferes with access to the meter panel.
|
|
Rusty ground connection666 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 MDU723 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, MDU543 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 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.
|
|
Up 'n Over!656 viewsMDU wiring run on top of the roof. The lockbox is unsecured and not grounded. Many workmanship issues here.
|
|
Weatherhead danger...821 viewsGround strap installed in the middle of power conductors. This is a dangerous situation for the installer.
|
|
CATV lock box grounded to a flood light607 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 power759 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 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.
|
|
Ground to Air Conditioner Cutoff switch592 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.
|
|
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).
|
|
No security here...1372 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 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.
|
|
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).
|
|
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.
|
|
A long way from the power panel...1476 viewsGrounded to a miscellaneous electrical conduit. Devices not properly mounted. Ground wire not secured. On this dwelling, the electrical meter panel is on the other end of the house about 60 feet away.
|
|
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?570 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 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.
|
|
Improper ground clamp501 viewsIn this photo, the installer has used a standard automotive radiator hose clamp as a ground clamp. This is not an rated or approved clamp for this purpose.
|
|
Ground to telephone473 viewsIn this photo, the installer has run a ground wire from the ground block to the adjacent telephone can and grounded it internally to the protector block. Not an approved method of grounding. In addition, the ground wire is not properly secured to prevent damage.
|
|
Improper ground connection395 viewsIn this picture, the installer has grounded the cable ground block by running a short wire to the screw that secures the electrical panel shut on the utility side. Not an approved method of grounding as it interferes with the panel operation.
|
|
Improper ground to an unapproved ground source456 viewsIn this photo, the installer has grounded his block by attaching a wire under a screw holding the cover on an LB box on a electrical conduit. Not an approved grounding method.
|

|
|
"Grounded" to a metal handrail (Part 1 of 2)568 viewsIn this close-up photo of a metal hand rail on a set of steps, you can see the ground attachment made to the top of the railing. This railing is not a ground attachment in any sense of the rules and a green tag does not make it so.
|
|
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 to power mast drop bracket419 viewsIn this photo, the installer loosened a nut on the back of the power drop attachment bracket and wrapped his ground wire around it. This is a violation of 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.
|
|
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.
|
|
Improper connection to an electrical meter panel396 viewsIn this photo, the ground wire has been installed by loosening one of the screws securing the riser conduit to the meter base and wrapping a wire around it. This is not an approved method of grounding. It does not utilize a proper wire lug.
|
|
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.
|
|
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 .
|
|
Grounded too close to the power weather head414 viewsIn this photo, the installer has attached a ground clamp in the immediate vicinity of the power weather head, and less than the required 12 inches distance from any of the power conductors.
|
|
Unauthorized use of the utility ground clamp608 viewsAlas, the installer has installed his ground wire under the screw provided for and used by the house grounding conductor. This action is not permitted by the NEC. Each service provider must furnish his own ground connection.
|
|
Plain and simple Not Grounded775 viewsHere, the installer wasted a perfectly good ground block by failing to install the required ground conductor. The job isn't finished until the ground is run (to Code).
|
|
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.
