Tutorial on how to install Cable TV Neutral Current Isolator

Eri Turalo 1 year ago updated by Shaun A Kranish (Principal) 12 months ago 1

Hi, I wanted to know how exactly do you do ground bonding part as described below at step number 4 for installing the isolator.

"4. The grounding (ground bonding) should be performed on the subscriber

side only. Otherwise you will bypass the transformer and the current

will still be there. The grounding is usually a female to female

adapter mounted inside the cable tv wiring box and it will have a wire

going to a ground rod or hooking to your electrical or something metal

on the electrical system nearby. So just make sure this is screwed-in

on the subscriber side. That safely "grounds" your cable TV wires

inside the home while electrically isolating your line to stop the

unwanted current flow."

Also, do I have to open the cable tv wiring box for this step? I'm looking to simply use this isolator for my cable internet from my ISP which is simply connected to a gray plastic box (cable tv wiring box??) that is locked and that I cannot access.


 Can you please explain more about this in detail especially the ground bonding part? I wonder if pictures can help me understand this better. Thanks.

The cable isolator we sell is labeled.  One end of it is "SYSTEM" and the other is "SUBSCRIBER"

The wire coming from the cable TV company must go directly into the SYSTEM side.  It SHOULD NOT connect to anything else or touch anything else metal.  This includes the little grounding brackets that are normally found with the cable connection to the house.  On the "SUBSCRIBER" side of our isolator, this is where you connect your house's wire.  You can and probably should also ground the subscriber side using the bracket that is probably already there from the cable company.  So you can hook their bracket to our subscriber side.

Just ensure that the cable from the cable TV company goes directly into the SYSTEM side of the isolator.  It should not go into a splitter or any kind of grounding block before it goes to the system side.  It should come from overhead or underground and the very first thing it should connect to is the SYSTEM side of the isolator.

That's all there is to it :)
