Drop control box1508 viewsThe drop control box is located so as to require the installers and techs to have to place their ladders next to power, and work within just a few inches of the power drop at the weather head. Also notice that the ground wire from the box runs to the old light fixture above, rather than to the mast of the power drop.
|
|
Not a neutral approach to grounding.1642 viewsHumm. A pipe clamp ground on...what is that...the power neutral. And, look, isn't that the ground wire resting on the hot lead of the power drop?!
|
|
How to clamp the power drop to the riser...1763 views...use coax. Actually, someone (sub? installer? tech? roofer? Santa?) has pulled up the slack of a drop by wrapping it around the service mast. Not the best of ideas, eh?
|
|
Down guy drop (Part 1 of 2)1782 viewsIn this unusual picture, an installer ran a drop cable from an overhead tap to an underground install by attaching the drop to the anchor guy and then burying the drop from the base of the anchor over to the house. Down guys are not cable supports.
|
|
This is a radiating experience....2576 viewsAs a new version of wireless. This splitter now provides a great radiating source for signal leakage as well as a twisted pair to service an additional outlet. The TV viewer was quite creative in this effort.
|
|
A little too close for comfort...1623 viewsAnother case of proximity to power. While trying to follow the other utilities, the installer has placed his P-hook and the drop attachment much to close to the power weatherhead. NEC states a minimum of 12 inches of clearance from ANY part of the drop at or prior to the attachment point.
|
|
Attachment to power mast1447 viewsA typical but improper attachment to the power mast above the roof. NEC prohibits the attachment of a drop to an above-roof mast that contains electrical conductors.
|
|
Use the power bracket.. NOT.1657 viewsCan't get much closer to power than to use their bracket as an attachment point for cable. Violates the NEC by being less than the minimum 12 inches from any part of the power drop at or prior to the attachment point.
|
|
Customer tampering2462 viewsApparently, a tv viewer in a lower unit of a duplex used this inventive way of connecting to the cable system. Twin lead is jammed into the coaxial connector of the cable system. Add this to the list of a million things you can do with duct tape. This is a good signal leakage radiator.
|
|
Down guy drop (Part 2 of 2)1556 viewsClose-up view of the cable drop at the base of an anchor guy where it is now buried over to a home. The installer apparently used the anchor guy as a means of getting from the overhead tap to the lawn.
|
|
Not an overhead drop, and not an undergroup drop, either.1679 viewsUnderground drops not buried to proper depth, or in this case, not even buried. Note where the cable crosses over the top of the garden edging.
|
|
It's supposed to be buried. That is why they call it an underground drop.1753 viewsAnother example of an underground drop without benefit of undergrounding.
|
|
It is such an obvious attachment point. Why shouldn't I use it??1714 viewsCable drop attached to the power mast above the roofline and in close proximity to the power conductors. NEC 820-10(b) requires a minimum of 12 inches of clearance from the wires, and NEC 820-10(c) prohibits the attachment to a riser that contains electrical conductors.
|
|
"The drop bury crew will be here tomorrow. I promise".....1870 viewsCable drops run on top of the ground rather than properly buried. These drops have existed like this for over 2 years, being moved out of the way to mow the lawn.
|
|
I didn't know you needed to secure the drops to the pole!!!1486 viewsOverhead to underground drops not secured to the telephone pole. NESC requires drops and cables to be adequetly secured to a pole.
|
|
More power, I need more power....1317 viewsThis drop attachment point places the drop as well as the cable installer much to close to dangerous power conductors. This placement violates NEC 820-10(b).
|
|
OK, that fixes the low drop problem....1426 viewsThis cable drop is tangled in the power drop, but, gee, it has very good clearance over the street.
|
|
Ungrounded Multiple Dwelling Unit Drops2001 viewsUngrounded MDU drops. In addition to being unsecured and the lid missing on this MDU connection box, the #6 ground wire has been completely disconnected and extends to the left of the box.
|
|
Drop conflict between cable and telephone1115 viewsCable drop runs under a main telephone cable. Interference to telephone facilities.
|
|
This could be a shocking experience....1203 viewsToo close to power. Lots of power. This drop is attached less than 12 inches from the main power feed to an apartment building.
|
|
A rat's nest of wiring problems1414 viewsMultiple cable drops attached to an apartment building. Workmanship issues here.
|
|
Under, over, through the power conductors1165 viewsThe installer ran multiple service lines up the wall, over the weather head of the power drop, and right through the middle of the power conductors. Violates the 12" separation rule of the NEC.
|
|
Fence wiring1148 viewsMDU wiring. Rather than secure wiring to the building, installers decided to just drape it along the fence and then run the drops to the building. Very poor workmanship issues (NEC 820-6).
|
|
Apartment wiring run amuck..1524 viewsApartment wiring. A great example of how to do it wrong. This wiring shows what happens when new wiring is simply put on top of old wiring and things are not cleaned up and put to code. We don't think the view out of the window is very pretty.
|
|
Wiring on the ground1462 viewsWiring on the ground. In this MDU, the wiring connections are left laying on the ground next to a rear entrance. This is a safety hazard and obvious workmanship issue.
|
|
MDU Security (Part 2 of 2)1504 viewsClose-up view of an MDU installation. NEC violations include non-compliant grounding and workmanship.
|
|
MDU Security (Part 1 of 2)1299 viewsPoor MDU wiring. Here's a good example of what happens when the cable operator outgrows it lockboxes (or perhaps doesn't stay current with system security patrols).
|
|
No one will see this. Why do a good job.1624 viewsIn this wiring closet on the side of a condominium, installers spent a minimum amount of time trimming and properly installing the ground blocks and ground. Not only was the work shoddy, the ground block is not designed to receive three ground wires. Multiple NEC violations here and poor workmanship.
|
|
No, It is not the drip irrigation system. Its multiple unburied drops.1075 viewsThis picture was taken in the parking lot of an apartment building with multiple drops from the street pedestal to the various apartment units. As you can see, very little effort went into burying the drops to a proper depth, much less any depth. Quite a trip hazard.
|
|
Lets Play Twister899 viewsCable drop is tangled in the telephone drop.
|
|
Cable drop situated too close to power952 viewsIn this picture, the anchor support for the power drop has pulled out of the roof and allowed the power conductors to come dangerously close to the cable drop. As evidenced by the pair of pliers on the roof and the blue tape on the conductors, it appears the owner was trying to make repairs without benefit of the power company.
|
|
Inductor loop and loose ground set screw1015 viewsThis is a picture of a meter bar style ground clamp on which the ground wire has been coiled forming an inductor. In addition, the set screw has not been tightened down on the wire, making it an ineffective ground.
|
|
How not to 'ground' to a meter conduit clamp1143 viewsGee, puting the ground wire under the screw holding the U-Clamp holding the conduit to the wall is certainly creative, even if not permitted by the NEC.
|
|
I do believe the cable drop is using the power attachment!1008 viewsViolates the NEC. Drop within 12" before the attachment; within 12" at the attachment; within 4" after the attachment; attached to the power mast above the roof.
|
|
Cable drop attached to a power mast above the roof...843 views...and below the roof, too! Violates the NEC.
|
|
Ground to, uh, well, uh...1114 viewsYes, that's a gutter downspout. 'nuf said. Well, actually I'll add that this isn't a NEC approved grounding point.
|
|
Drop melted away from messenger1183 viewsA significant power hit on the drop caused the plastic jacket to melt away from the supporting messenger cable. Note the drips of melted plastic below the coax.
|
|
Just a tad but too close to power, don't you think?1117 viewsMultiple violations of the National Electrical Code. First, the cable and power drops are less than 12" apart prior to the attachment. At the attachment they're less than 12" apart. The drop is attached to the power riser above the roof. There's more, but I'm out of room.
|
|
Hummm. Loose wires?1271 viewsAcross the street from the cable company's headend and offices.
|
|
How to store spare ground wire1435 viewsThe NEC requires that a ground wire be run as straight as practicable. Coiling the ground wire isn't that method, and adds impedance to the ground wire.
|
|
Ground clip blocks breaker box door closing1180 viewsHeck, you don't *really* need to close the breaker box, do you?
