New TV tripping breaker; cable connect gets hot


Help! New TV trips breaker only when cable plugged in. Older TV doesn't trip it (with cable plugged in). Any suggestions? Thanks!

Is the breaker an afci or gfci breaker? Usually you will get leakage to ground because the coaxial cable is grounded and will cause a gfi to trip

Considering the only thing changed was the television my 1st thought would be that somehow the television is defective! Especially since you said in your title that the Coax was getting hot. I would return the television to where I purchased it and let them test it in store. I would certainly do that before trying changing things in my home.

Is you new tv grounded ? or is it double insulated ?
What about the old tv ? Was it grounded or double insulated ?
If the cable is getting warm, that indicates that there is current flowing
back to ground thru the coax sheilding.
Its not unusual for some tv's to have some leakage,
It's not really a fault, as some leakage is allowed.
And also your electrical system plays a part as well,
sometimes its someone else electrical system that can be faulty,
but using your systems ground to return home.

Have you tried using another tv on the cable box ?
This will indicate if the tv's playing a part or something else.

Measure from the cable company coax to a known ground in your home. If you get a voltage reading from the nut or the wire in the center it is cable issue. One of their pieces of equipment is defective.
If your old TV did not have a ground pin you would not have noticed it.

hmmmmm some leakage allowed? Enough to trip a breaker? No way..

Faulty TV return it asap. Even if it tripped a GFCI (6mA leakage) I would return the TV. To trip a 15A branch circuit. There is no scenario where this is OK.

We don,t yet know for sure, if it is just a faulty tv,
There could be other factors at play,
contributing to the problem.

Do your gfci's trip out at just 6ma ?

Ours trip out at 30ma.

I assumed what you guys called gfci is the same as a RCD !
So they are not the same ?

We used to have years ago,
devices that actually monitored the currents
flowing in the earth line, and cut out if too high,
these were the original "earth leakage breakers"

Is this what you term a GFCI ?

are there still two different types in use RCD's and Earth Leakage breakers ?

Mostly earth leakage types are not used anymore in Australia.
There all RCD's.
