Title: This hobby is driving me crazy.
Post by: omarshabaz on July 26, 2010, 03:32:46 PM
I need help.

I finally get the rest of the components to get the tank exactally where i want it, and when hanging the new lights yesterday I get a 110 volt shock from the aquarium.
9 system is about 1.5 years up and running .) Get out the volt meter and start individually unplugging and plugging back in and everything is contributing 15 - 25 volts, 3 koralias, heater, and return pump. So now what do I do replace all the equipment. the heater is about 3 months old its a stealth titanium, koralia's are about 1.5 years and the return is a quiet one 4000 about 1.5 years as well. We had just moved so no GFCI yet but they are being switched today.

I feel like I should just give up and cut my losses.

Koralias and heaters first.
Do yo have urchins or triggers?
They like to eat power cords sometimes.
Unplug those first and see what happens.

no urchins and no triggers. Everysingle item seems to be affecting the number by 15 or 20. Pull out all the koralia cleaned them real good and still no change, i checked the cord for tears or puncture marks and there was nothing. Would switching out all the koralias for one vortech mp40 in a 125 with softies be enough flow.

Something tells me it isn't going to be all those items.  Possibly a ground issue somewhere?    Just seems odd that EVERYTHING is contributing.

Post by: omarshabaz on July 26, 2010, 04:19:48 PM
not too sure, I pulled each item one by one and tested them individually with a different plug and got the same readings.

Maybe it's the new lights.  You said you were hanging the new lights????????

If everything old has been working correctly?????

The lights werent plugged in yet, we were hanging the lights and i touched the chain while my hand was in the water is when we noticed. What is an acceptable level of stray current.

you can ground the tank with a titanium probe but finding the problem is better. not sure what an acceptable limit of stray voltage is but i know some three way switched for your house have about 20-30 volts of stray voltage

Not sure what an acceptable level of stray current... I'm guessing 0, but heck knows...(kinda makes me want to get my multi-meter out)

I'd recommend that you look once more... maybe take all of the devices out of the tank to start and confirm a 0 reading... then test each in a bucket of water in contrast to the tank?

Good luck

remove each item again and this time check them one by one in a seperate bucket of salt water. I bet you will find that the problem is either one item or maybe something you've missed in the tank.

OOps,
Sorry Hookup, we replied at the same time!  I guess great minds think alike  ;)

Check all wires from the ballast to the sockets, they should all be good with no missing insulation to be grounded. The stray voltages you are talking about should be zero. If you do have some stray voltage, you will kill everything in the aquarium including you if you ground yourself good. It could be bad ground like a loose wire on a socket.

Just a thought... is your tank on a metal stand? and if so is it on hardwood or carpet? What's the humidity level like in the area around the tank?

I'd definitely suggest verifying a zero reading with all equipment out of the tank. 
Title: Re: This hobby is driving me crazy.
Post by: omarshabaz on July 27, 2010, 11:33:57 AM
Zero for sure with all equipment out of the tank. it is on a wooden stand on carpet in the basement with low humidity.

OK they are out but in the tank, one at the time, what is the stray voltage individual?
Title: Re: This hobby is driving me crazy.
Post by: omarshabaz on July 27, 2010, 02:51:29 PM
Pulled them all out and used a different plug to verify with a bucket of saltwater.

Koralia 4   19.23 VAC
Koralia 3   17.11 VAC
Koralia 3   23.22 VAC
Heater     18.11 VAC
Return      13.71 VAC

Something doesn't make sense that you are getting leak from all the items..
Title: Re: This hobby is driving me crazy.
Post by: nissannx on July 27, 2010, 04:00:52 PM
that is alot of stray voltage. what are you using as a ground to test?

Darn good question...

It seems odd... either the test is flawed, or devices naturally leak voltage... I just cannot fathom the odds of each one of those being faulty...

Not suggesting you are doing anything wrong at all... i'm as puzzled as you...

Volts are not my thing, baby... haha.

We are using the hole on the electrical outlet.
Title: Re: This hobby is driving me crazy.
Post by: karjean on July 28, 2010, 07:16:20 AM
The new fixture, is it a plugged in type? Could you provide a picture? run an extension cord from another room receptacle, ie. kitchen counter split plug to have it from another breaker source. It could be your receptacle or the circuit being faulty.

This is crazy but true. I lived in place where the outlet in the bathroom didn't work. Made it tough to shave having an electric razor.  >:( Asked landlord to change it he knew I had a background as a apartment super so asked if I could change it I said sure. After I shut off the breaker pulled the plate unscrewed the outlet grabbed it to pull it out of the box and ZAP "Holy S~%#" I yelled. Any ways the end result with the landlord was a nightmare (not just this isse) and the ESA ended up in there (along with many others). They tested and determined someone had wired the ground hot. Maybe test if the ground is actually zero on that outlet (or others)? Just a whacky story...

omarshabaz did you found the grounding problem? I did had a friend a while ago which had the same problem at his  farm and found out the bad receptacle was at the house at another location. You could start to isolate some circuits by turning them off at the electrical panel.

This is quite possible also.

Havent found it yet.

Try to isolate every circuits in the house one by one, and test as you go. You might find it this way, as you turn the breakers off, leave it off; but make sure it is only one circuit being turned off at a time. Once located which is the faulty one, turn all other ones off and keep the faulty one on and test all receptacles with a desk lamp so you know which one are on that circuit.

Wondering if you have found the source of the problem?

You stated that you just moved.
Simple way to test household wiring to see if HOT, COMMON & GROUND are wired correctly.
Receptacle tester / Circuit Analyser
http://www.canadiantire.ca/AST/browse/3/HouseHome/2/Electrical/ElectricalTesters/PRD~0520027P/GFI%252BReceptacle%252BTester%252B%252526%252BCircuit%252BAnalyzer.jsp?locale=en
Best to start at the source - the plug in the wall.
Most of today's electrical equipment - if not equipped with a 3 prong plug w/ground - uses polarized plugs.
Again, if the power source is not wired correctly, current will flow the wrong way.
I know, all of the electricians out there will say it doesn't matter - its AC - it alternates on its own.
But if not wired correctly - 3 prong w/ground or polarized plugs will not provide the electrical protection they were designed to provide.
Just a thought - start at the wall - all your equipment might just be OK and the problem is at the power source.

If you are using a multimeter try metering these:

Hot to neutral - you should have anywhere between 110 and 120.

Hot to ground - same result as hot to neutral

Neutral to ground - zero voltage  (or it will show millivolts)

Be sure that it is showing either zero or millivolts (a small "m" in front of the "V").

If you have anything between neutral to ground you need to make sure the socket is wired properly or that the house is wired properly.  All neutral wires in your house are only supposed to be bonded to the ground bar in one location.  If they have done it in different locations (or God forbid to water pipes) then you can have grounding issues or even a ground loop.
