| What needs to be grounded at install?
and WHERE is the best place to ground it? Should it really be ran back to the ground rod outside or is connecting it on the ground cable next to the panel good enough?
The ONT is grounded but the 8-way splitter is not. The installer just forgot about the splitter, and I'm wondering if I should ground it. While I'm doing it, should I run it outside to the ground rod grounding cable.
I did have problems with my AV system a while back due to grounding issues (still have them btw)and wonder which way to go now to avoid further problems that may occur with this system. |

East Northport, NY | The splitters do not have to be grounded.Only the ONT needs to be grounded and that is a good ground. There will be no advantage or change in the picture if you go thru the trouble of grounding the splitter. VZ techs never ground the splitters. |

| OK, but there IS a ground screw on the splitter and the installer did say he would ground it, but just got busy with other stuff throughout the house and forgot.
Having said that, I don't mind if it's not grounded, if it works properly of course. The only reason the question came up, is I did have a grounding problem in the past AND I have a noise on my phone which I thought MAY be from grounding. I doubted this was the problem, but I figured I'd ask anyway.
thanks for the help. |

West Chester, PA | Mine's not grounded either. Althoug it is sitting on the ground of my crawl space, but somehow I don't think that counts  |

The noise on your phone could be caused by the ground on the ont. If you plug a phone straight in to the ont and the noise is still there this is probably the issue. |

East Northport, NY | Or he could just have a problem with the inside phone wire in the house.
Very rarely is a noise problem caused by the grounsd at the ONT --or lack of ground. |

| Actually the ONT is not grounded, it is bonded to the existing electrical service ground.
If you have several VCRs on your coax circuit, grounding and bonding the splitters will help with foreign voltage (AC) coming from the VCRs. The FV tends to cause some picture problems and generally not noise on the phones.
Phone noise is another can of worms. What kind of noise? Static? Hum? Cordless phone? All phones? Nearly every case of noise I have been to can be attributed to something wrong with the inside wiring.
So what is the problem? (Specifically) |

| I disagree. the ONT is connected to the PSU/Batterypack which is grounded (as you put it, bonded to the existing electrical service ground)... well whatever you call it, its grounded In general, devices that are grounded are the ones that have a strong chance of a human getting shocked.. notice devices in all plastic casing and that are electrically isolated never have ground plugs.... That being said.. splitters should be grounded at some point, and it has less to do with human shocks, but more to protect the devices connected to the coax... who wants to chance frying a S3 Tivo....
As for how often you should ground something, it is not neccesary to ground electrical devices multiple times (it does not hurt, but in most cases it won't do any harm either). One of the reasons to do it, is power always takes the shortest path to ground (the path of least resistance).... in a short, especially on long cable runs, it can become a fire hazard as the longer the run, the longer (measured in ms) it takes for a GFE to trip.. which can cause heat, which can be a fire hazard... but this is going to the extreme end of problems, and is not likely. |

(Specifically) Here's the other thread I made specifically about the phone problem. »Phone making a noise.
Not sure if I could post it here... This thread was for the specific grounding question, but it did have something to do with the phone issue. Sure, they could be related.
Anyway, my phone makes a continuous fft, fft, fft, fft, sound 2 or 3 times per second. It is a corded phone hooked up to a multi-phone system.
Just to clarify, I did get replies to the phone issue before and I'm not disregarding that advise. I do appreciate the interest in this question. |

You are partially right and partially wrong. The JIONT has a 3 prong ground. The PSU that is separated from the BBU and ONT is only a 2 prong. The 3 prong receptacle that the JIONT is plugged into may or may not be wired or grounded properly. I see this stuff every day.
On several occasions I've had to add additional grounding to splitters where VCRs were the culprit and putting AC on the coax.
The current policy for grounding says that the ONT will be properly bonded to the electrical ground. There are other places the technician can bond to if they are closer than the electrical ground and as long as they provide a low resistance path. |

My installer ran a brand new 6 gauge copper ground wire from the ONT to my grounding rod.
