:shocked!:

Come on Doug, it's only 120V!!! :lol:

Yes. Most new places now require them by code in bathrooms/bedrooms.

I'm an electrician and I have never heard of a combo breaker...Bathrooms by code have to have a GFCI while bedrooms have to be on an ARC fault breaker....An ARC fault breaker will not trip when their is voltage leaking to ground it will only trip when their is a all of a sudden increase in current kinda of like the same way a normal breaker trips but ARC faults are much more sensitive cause they use a MCU instead of a Bi-metalic strip!

It's odd to here that with absolutly nothing plugged in that their is 9 volts in your a aquarium, I am leading to believe that the meter is faulty...check it by putting it into a recepticle to make sure that you are indeed reading 120 Volts.

Once you've had 600 Volts surge through your body, 120 volts seems like child's play!!!

Hi Kevin, Thanks for jumping in here.

My breakers say

Arc Fault
& GFCI
Breaker
Type BRAF
<--- GF Test AF--->

Anyways I,m off to check the meter. As I posted, everything seems to add its share of current.

So it reads almost 122v. Not enough out for the 9 volts. Would it sense a 9v battery in a digital thermometer?

GFI/ARC fault breakers, they are used in bedrooms with ensuite/bathrooms that are part of the room.

Yes, thats where mine are for. Also in modulars, the two end bedrooms and bathroom are on one circuit, thus my office/tank room. I had a separate circuit run to anormal 15a breaker and use both. I do use a GFI on the normal circuit also.

Nothing has tripped anyways, including when I put the ground probe back in.

Update time. Lucky I can still type. :lol: Could not trace it to any one thing but a combination as I mentioned before. Both my Tunze 6080 & Hydor seem to contibute about half each of the 80v I measured. heaters and other stuff is fine.

Nothing registers with the ground probe in though and I can touch water to ground. :lol: So working on my 90g today, moving things around and finding them a home. Of course my ground probe is in the sump still, which is not part of the 90g. I touch my forehead on the reflector, {halides off}, while working in the water and WHOLLEY MACKERAL. It flashed and everything, my forehead that is. :lol:

Crap, did that liven things up. Get the meter out again. Same measures as before. Put ground probe in tank and no current. Unplug pumps, leave ground probe in, plug Tunze back in and out goes my GFI/ARC fault breaker. Plug the Tunze into the other normal circuit and alls fine. But my ground probe is still in.

And thats the story for now. Why the heck does my Tunze leak 35v? Why does the other pumps do the same? Can anyone else measure any current in their tanks, without a ground, coming from submersible pumps.

You must be afraid to go near your tank.

Measure between the reflector and a ground point, right a receptacle. Rather than your lights being the ground, they might be the leak.

Hey there doug just reading your post and may be you should check your GFI plug to make sure that it is grounded first off , if not its just like a normal plug..
