Advice required please urgently

I would suspect 12V or so coming down from the loft box as it has a magic eye.

How do you know the radiator is connected back to the Main Earth Terminal?

Have you connected a magic eye to the antenna cable before you plug it into the tv?

it's tripping with one of my TV's plugged into the ring main, but only if the aerial is plugged into the TV (I have a tv loft box and sky+ with tv eye links).

Hi mate,

I might be way off with this - but could these 'tv eye links' be the cause of the problem?

From what I remember, they operate by being connected in the aerial cable and powered via a 'low' voltage applied at the RF output on your Sky box.

Is your Sky+ box powered from the same circuit as the TV that is causing the tripping?

Just a thought - it might not even make sense.

You can notify someone else's work if they work for you and you are the registered supervisor. But I think people working for you have to be on the records with the scam?

You have to be part of the same entity.

They work by introducing 9v DC to the INNER core of the coax.

NO current whatsoever should flow from the inner of the aerial socket to either L or N so if that was the "cause" then the tv is faulty.

Also, the sky box is double insulated, so no current will flow from it's 9v source to either L or N at the sky box end either, again unless it's faulty.

That's why in an earlier post, I'm beginning to suspect the improbable scenario of TWO bits of equipment are both faulty.

not all. there are still some class 1 boxes around (very few. mostly older ones)

 

[steptoe]

where has this sky box appeared from,

OP stated a TV,

or is he simple being economical with the truth.

the more I read this thread Im starting to agree with an earlier poster that "may have suggested" that somehow the OP is having some sort of issue with his electrics tripping out due to a fault of his own now he has a newer sensitive consumer unit fitted and is trying to grab straws to blame the installing spark for something/anything so he has some form of comeback/revenge for his electrics now being safer and showing up inadequacies in his existing appliances.

i was starting to think that after the first post....

I knew deep down it didn't make sense - strange that it's just one of his TVs causing this problem - and only with the aerial plugged in.

Assuming its functioning as expected.

From here, Steps, opening post

An electrician has fit a new fuse panel (Twin rcd etc) and it's tripping with one of my TV's plugged into the ring main, but only if the aerial is plugged into the TV (I have a tv loft box and sky+ with tv eye links).

Reread OP fully

 

[steptoe]

yes, a loft box to me would be an amp,

his sky+ is obviously on a different TV,

he says nothing about an eye on this TV.

all this should have been disconnected before he can blame his spark for a fault that isnt there.

BTW, it wasnt me, it was Harold.

Guys

I'm not grabbing straws to avoid blaming my equipment, I just want an answer to the problems, if the tv is faulty I have a warranty or would buy a new one. The other equipment isn't that expensive either individually but i can't keep buying replacement pieces of tech unlit I find the faulty one (if it exists) when some testing should be able to find a fault.

If i unplug every single device in my house including sky and the power to to the loft box the lg tv trips the rcd once the aerial is plugged in again.

The interconnections between all the gadgets work fine normally but i appreciate the new rcd is more sensitive due to it's design, and good on it. However, there are plenty of people running way more complex systems than me and they don't trip out, so something is a problem and my electrician has no idea and has shown no inclination to get involved, he was hoping for an easy install and now it's gone slightly hard he's clearly way out of his depth and back peddling with his verbal agreement. He may well turn up tomorrow with a different attitude or at least prepared to check the sockets, but my experience so far is he didn't even understand what the tester was telling Him. The tester doesn't work for their company, they appear to be a 2 man band and he was contracted in for 2 hours cash job to test and certify.

The 'high' reading was something like 1.3 and he said over 1 was bad and it needed sorting...but the electrician didn't have a clue where to start and legged it for the day..

Like i said earlier, it's possible i have 2 issues, one could be the tv has a strange fault, but this high earth reading happens will all of my equipment unplugged so cant be my fault... Could be a simple socket with earth hanging off the back..

 

[sparky b]

With all other appliances un-plugged have you tried connecting the ariel lead in to a different tv?

 

[Andy™]

high earth loop will not cause your problem. infact, with a 30mA RCD, it can be upto 1667 ohms.

IR test of the circuits will highlight any fault on the fixed wiring. can also be used to fault find on appliances, but not on something sensitive (would work on something like a kettle or heater, but will most likey do damage to TV etc)

 

[steptoe]

TBH a high ZS reading would possible lessen the likelihood of this kind of fault,

yes you have a fault,

no, its not in the sparkies remit of changing the CU to find it,

its obviously one of your appliances.

yes, in decency he should help you out,

but, are you wanting him to do it for free,?

1/2 hour, maybe an hour at most,

then, sorry,

its not my problem, you appliance is faulty.

I could narrow it down for you, my price is

Right.

Unplug ALL the other aerial leads into and out of the loft box, so you have JUST the tv plugged into the mains, the loft box plugged into the mains, and just ONE coax cable plugged into the loft box, that being the one that feeds the aerial down from the loft box to the offending tv. The ONLY thing plugged into the tv must be the aerial lead from the loft box, no scart leads, hdmi leads or anything else, no DVD players etc.

Does the RCD trip?

If yes, then in all probability the tv AND the loft box are faulty.

If no, the RCD does not trip, then start plugging the other cables back into the loft box, ONE AT A TIME, i.e the aerial feed into the loft box (from the sky box in the other room) then any other outputs to other tv's.

Then tell us which cable being re connected causes the trip.

If still no trip, re connect, again one at a time, all DVD players, freeview boxes etc.

If you can, sketch out a detailed drawing of ALL the tv's, sky boxes, freeview boxes, amplifiers, splitters etc so we can fully understand the installation.

Hi

Yes I have and the rcd doesn't trip. 6 other TV's in the house all plugged into loft box also work ok. So maybe the lg is faulty, i could take it to a friends house and see if it pops their rcd (quite big to get in a car tho) but if they don't have a loftbox is it a true test? Of course if it pops rcd without a loft box then it says a lot....

That still wouldn't explain this high reading that he was very concerned about, or perhaps the tester is wrong from what some if you guys say the high readings are almost expected.

I don't have a problem paying anyone to help, my grievance is mentioning extra money when it's to do something he's already told me was built into the price in advance to cover 'these types of scenarios'.. Especially when he doesn't seem to even understand it, he was blaming everything he could from remote control light (which is on light circuit not ring) to 6 was surge protectors, the rcd plugged in the garage socket for the lawnmower and i think the unplugged kettle got accused at one point too.
