One dish feeding several homes

winston_1

This is often stated as being electrically unsafe. The argument usually goes that alternative homes are on different phases, thus there is 415v between the live mains of each dwelling.
Of course to get a shock situation would require faults at both locations simultaneously.
One can protect against it by earth bonding the dish and all cabling. This is exactly what is done in blocks of flats that use a communial dish.
Even a temperary connection from a neighbours dish can be safely protected by earthing the feed where it enters the house.
Cable companies that feed multiple dwellings use a different method of protection, isolators on every feed. This method cannot be used on satellite as it would block the LNB switching signals.

So let's put this myth to bed now. With the right earth bonding it is perfectly safe.

Don't think that anyone is arguing against connecting to multiple dwellings where all are bonded back to a common earth.

When I suggested earth bonding in the other thread you said it was against electrical regulations but declined to state what the actual reg was.

The danger arises when you have people with little or no technical know-how being advised to hook on to a neighbours dish.

That is true, which is why I said to earth the feed.

Tony

I think you misunderstood. How could earth bonding be against regulations ?

Earth the feed how ? Not exactly an easy DIY job for most

Let's re phrase it. When I suggested earth bonding you said connecting to a neighbours dish was against electrical regulations earth bonded or not.

You can get f in line connectors with an earth terminal on them for this very purpose. But obviously if the DIYer cannot do this that is another matter.

You still have not said what this electrical reg is.

Tony

I think you know full well what I meant and are trolling at this point.

No. I ask again what is this regulation?

In fairness to winston I dont think he is trolling. It looks to me like you have wronged him here.


It was stated in the other thread that:
"NEVER do this ( for reasons of electrical safety) "

And you agreed with the general statement of "NEVER".

winston wrote back to state that is was fine to do as long as it was earthed.

You then replied with

Its against electrical safety regulations which are there for good reason and would invalidate and public liability insurance the installer holds if he knowingly did this.

End of in my view

You now seem to have back tracked from that original "NEVER" position to now accusing winston of trolling and still not stating what the regulation is.

I think its time to admit you got it wrong here.

In fairness to Tony, I imagine he is thinking of the many non-technical readers of this forum. Qualified, fully trained people will know what can be done.

Tony

If you are going to accuse me of wronging someone then at least quote the context. I'm not backtracking on anything

pity you dont have a friendly neighbour with a free lnb not too far away you could borrow a sat feed from and when leaving
give them back the cable.then you have freesat and use an indoor aerial for saorview.

I agree with Rippy on this . If the neighbor has a dish then its logical to assume that no communal system is in place (unless the neighbour is running one which is unlikely ) If a communal system is in place then you would connect to a multiswitch which has earth bonding back to the buildings earth and not connect to the dish.


What was being suggested was something else entirely

Tony

Exactly Gerry

I did quote the context. You agreed with the "never" sentiment and winston simply stated that it was possible as long as it was earthed. You then seemed to take issue with winstons response citing insurance issues and regulations without backing that up. On this thread you seem to now agree with him

Winston also said it may not be for a non techie DIY'er so that's a mute point. His point was that it could be done and you quite obviously disagreed with him in the other thread.

From what I can see on this thread you both agree on how it should be done but you don't want to accept you wronged him on the other thread. Calling someone a troll was unwarranted.

I'll try to stay out and let winston fight his own corner here. I just felt it required some impartial balance.

Tony

That is not the case at all in the context of the previous thread which spawned this one. But you are right Winston is well able to make his own case.

Why on earth would u need one dish one one property to feed other homes, each should have their own for not only safety reasons but for others reasons as well

* To be able to easily add more connections to additional rooms.

* Less cables seen going across gutters and even when it's put in ducting when something goes wrong costs involved on rectifying or replacing cables is too large.

* When a dish is damaged the homes that don't have the dish on their property will expect it to be free, always the case with communal systems.
*If I owned the home the dish was on I wouldn't want every tom dick and harry coming onto my property.

In areas where homes are blocked by trees I can understand but everywhere else it doesn't need to be and shouldn't be done ....their is simply no reason to.

Tony is completely correct, I have seen damage done on more than one occasion one of which was struck by lightning and no earth bond in place causing extensive damage to two homes ,as rite fully stated an idiot did the work, not electrical minded, not tested by any electrical body didn't have a clue what he was doing simply cutting corners and doing it for cash and under the counter and UN-contactable afterwards...it therefore shouldn't be done.

We professionals have to clean up enough mess as it is..

Come to Limerick and I will show you two estates fed from communal systems now both defunct as done on the cheap and nobody was ever willing to pay to fix it when problems arose. Now as a result there is a communal dish doing sfa, and wires all coming down the newly insulted homes, a rite mess...

a bit too much anger here methinks, maybe if people are willing to cool it there might be an issue to discuss here
