Even if the power supply was grounded through the house power outlet, you still need a direct ground from the ONT to the home's power ground wire.
With your logic, if a cable modem or TV connected to cable is plugged into a grounded power outlet, then the cable wouldn't need a ground block. | |

 |  | | Reading the attachment in the complaint it seems the issues they cite are with workers being killed by electricity while installing FiOS or FiOS related equipment.
I'm not sure how revisiting each job will help. It's an issue with internal safety practices and enforcement. | |

I don't know how many stories I've heard from around different industries from people who get a jolt and end realizing that they forgot to ground, power down, ad nauseum.
The only thing that re-visiting each install does is cover Verizon's ass in the event that it becomes an issue where subs are getting zapped. -- --- Eleven years of carrying The Clue Bat... | |

(1) They don't practice drilling through electrical conduit during "installer classes". (2) They expect their installers to be practiced enough to not drill through electrical conduit.

 GeekGirl1Premium join:2007-01-28 Morrisville, PA kudos:2 3 edits | Doesn't everyone check the install? I've got my ONT installed in my basement. Verizon ran the ONT ground wire to an ungrounded workbox near the install. After they left, I re-ran the wire to the same cold water pipe that's used for my service entrance ground.
There are a threads ad-nauseum in the Verizon FiOS TV and Verizon FiOS Fiber Optics forums about grounding. My postings about this install are in the mix, all is OK.
Bottom line is that it's Verizon standard procedure to ground the ONT. Of course the fiber is plastic, but you have to realize that you are connecting to other services such as coax cable and phone lines that require proper grounding- hence the need to ground the ONT. | |

 |  | | When my cable was installed several years ago, the installer pulled the insulated green ground wire through a vent into my crawlspace and wrapped 1 loop of the insulated wire around a rock laying on the dirt floor. I guess electricity knows it has to exit at the rock and look for the dirt to finish it's trip to the ground. | |
|
 | | Blame it on Productivity Grounding the ONT properly is the techs responsibility. Verizon management hammered the techs to get the jobs done faster. I am sure that skipping the ground wire is done all the time in order to speed up installations. | |
|
 |  | | Re: Blame it on Productivity And how do you figure this when the VZ techs even on this board state that they're given such a large install window they can and do take their time?
It's called those "skilled" techs are just lazy! And claim they can't be replaced? HA! This is a good way to get replaced.
VZ needs to go back to these installs and find out who actually finished them. Get out the pack of pink slips then tell those techs to f*c* off because they're done! and let VZ hire a non-union installer who chances are would check the install AFTER its fully completed a 2nd time. | |

 |  |  |  |  | | Re: Blame it on Productivity Read the complaints. This has nothing to do with actual grounding issues at the ONT. There's no proof the Verizon workers bonded and grounded the ONTs wrong. | |
|
 | | Bonding In telco installation "always time to do it right the 2nd time " is a standard theme but bonding the sheath is important because lack of bond can hurt you. If you were up a pole a grabbed an non-bonded line the induced charge from overhead power lines can knock your dick in the dirt-I've been there with old "dead" open wire out in the burbs.

 | | Permits and Inspectors? I guess no permits need to pulled for installation of these devices. Building inspector or master electrician is supposed to inspect and sign off before power is turned on. If this is not done then the agency that is not requiring final inspection takes responsibility for injuries in court of law. | |
|
 |  | | Re: Permits and Inspectors? Before installing any additions to anything an enginner and inspector soppose to approve the build some states have different electric codes. | |
|
 |  |  | | Re: Permits and Inspectors? I agree with prelim work by engineer etc. My point is that you are supposed to have an installation inspected and "approved" before turning on the power. Has the federal or state governments removed this requirement for this type of equipment?
For the record I am an electrical engineer with a PE in my home state. | |
|
 |  |  |  | | Re: Permits and Inspectors? The ONT only draws 12V,38W max FROM the customers wiring. The FiOS network is totally passive, no current at all. If anything, the ONT needs protecting from the customers faulty wiring. | |

 elbm join:2000-08-03 Reisterstown, MD | ONTs do not require grounding The specs from the manufacture do not require the ont be grounded. It is a Verizon M&P that requires grounding. The ont is powered by dc from a transformer and the optical drop is non-metallic. There is no real reason to ground the ont other than an over zealous M&P. | |
|
 |  GeekGirl1Premium join:2007-01-28 Morrisville, PA kudos:2 1 edit | Re: ONTs do not require grounding Sorry, no. Just search the forums and you'll get a lot of reasons to do it. Like here: »What needs to be grounded at install?. You have to connect the ONT to other services like coax cable, ethernet, and phone lines which need the ground. | |
|
 |  |  elbm join:2000-08-03 Reisterstown, MD | Re: ONTs do not require grounding I did not say that there are not reasons to ground the ont but it is not required by the manufacture for the ont to perform properly. | |

 NOZIREV join:2008-07-10 New Bedford, MA | You peeps are making it sound like you have to ground the ONT. That is a lot harder than what really needs to be done. All you have to do is bond the ONT to something that is already grounded (ie copper braid from electrical service, cold water copper pipes, copper ground rod, oh and dont forget the gas pipes . anywho it takes very little time to do a bond and i agree with the geekgirl1 on this issue. | |

 JSYPremium join:2000-04-05 Elmhurst, NY | The real point... is not so much as whether grounding is required, but whether or not the installers were following instructions. If they didn't not properly ground because Verizon told them to do it that way, then fine - Verizon has to fix that issue and retrain the installers. However, if the installers didn't install it properly by way of not following Verizon's instruction, then all I can say is - look, it's already happening. They're getting lazy and careless as the TWC, Dish, etc. people. LOL! | |

 | | Grounding vs Bonding Grounding is to provide voltage reference and remove "noise".
Bonding is to make enclosure same potential as rest of area so someone does not get shocked or killed touching the enclosure.
Bond wire and ground wire are not the same except at source of power which is most likely a transformer secondary. The ground wire and bond/ground grid should only connect at one point.
What does this mean? The cabinet, if it has active electrical devices should have two non power wires, one for establishing ground and one for safety bonding. For higher voltage installation you normally have more than one bond connection. | |

 | | Tellabs ONT I can not speak for anyone else but my Tellabs 1611 ONT has a 12VDC (14.82) feed from the VDC/battery charger that receives a 48VDC feed from the AC/DC converter. The AC side of the converter is supplied via a standard 120VAC grounded service. The ground lug on the ONT might just be just a signal/safety ground. Since the ONT is DC powered it does not require a ground to function but the return side of the VDC is usually tied to ground for reference and the ONT does produce a RF signal, that service usually requires a reference ground. Also there are status signals that go between the ONT and VDC/charger. These may also require a reference, not saying they are RS-232 but may be similar. Just my opinion, would be nice to see the schematic for the ONT. | |
|
 |  | | Re: Tellabs ONT I figure the ground lugs are there, so ground.
Additionally, there are some remote tests that require a reference to ground. For instance, there is a remote test that electrically removes the telephone house wire from the ONT circuitry then tests it for AC/DC voltage and resistive faults. | |

 | | ground length Ground specs as I know them---fios installer west coast---is 10 gauge wire not to be more than 20 feet in length, no 90 degree bends, first choice is existing telco bond, edison neutral. If there is no bond available, then the install is not supposed to go forward till one is provided.

 | | Grounding I live in Florida along the I4 corridor which is lighting capital of US and possibly the world. I spoke with a Verizon tech I know he advised the grounding is to protect the ONT and electronics. I you have an inside ONT they dont even have ground it to the MGN. The only times they have ground the ont to the mgn is if its located outside or if there is over 6ft of exposed coax/phone wiring outside the house. The inside ont have 3prong plug and that is all that is needed. All grounding is just to protect the equip. HTis leads to believe that whas going on in NYC is just an act to delay FIOS penetration. | |

 |  |  jfoj join:2005-05-06 Mclean, VA | Re: fios grounding I could care less about protecting the ONT and Verizon electronics (except if it is my service and I do not want a potential outage or service call), but the ONT should be properly grounded/bonded to eliminate ground loops and to protect users from stray currents.
With TV's, telephones and network gear all connected to the ONT (which is typically located outside next to the power drop to the house) you would want the ONT grounded/bonded to reduce problems from lightning to the homeowner or contractor performing work in the house drilling or cutting through AC lines and shorting them to cable/phone/data lines and lighting up the entire signal distribution plant with AC Voltage.
If the hardware is properly grounded/bonded, then most likely sparks will fly, breakers will trip and someone will know there has been AC coupled to the signal wires. Worse case if if the hardware is not properly grounded/bonded, you can have signal wires with potentially hazardous Voltage for an unsuspecting person. Sometimes the problems do not appear until a signal cable is actually disconnected, removing a unknown ground/bonding path, that the problem become evident.
Hey, just ground/bond everything properly for everyone's safety.
