You guys are really making me sick!

You really have to check the stray voltage like in the picture below. Please post the results here.

Right now, that is the solution, but I think we will work something out something slightly different.

oK i HAVE DONE THIS AND MYNE IS @ 250!!!!!!!:eek::eek::eek::eek::eek:
 
Hi all


Any suggestions what I can use as a ground probe and where I can get it in CPT?

Hey buddy you point to the Earth point on the plug as the earth leakage in your drawing, that is merely the earthing point of the plug. And that point "should be" connected to your main earth in the DB to enable the earth leakage to pick up a fault from neutral to earth and enable the relay to trip. SO itll be deemed worthless having everything connected and not the main earth to say the least. But your way of explaining the testing procedure is correct.

Yes it is the earthing point of the plug. But that should be the very same like connecting to the DB. If I connect the ground probe via 15 m cable to the DB or connect it to the earthing point of a plug, I has to be the same. Sure that earthing point has to end up in the DB.

So I don't really understand what you mean!

That is absolutely seriously dangerous shit your doing eish. And that just tells me that there is no tripping protection on your system brother.

I also thought the very same. The house was sold to my landlord not even a year ago.
So how can the E.L. not work? Electrical certificate was probably just signed and the system never tested.

I am still battling how to measure Amps with the new multitester. The manual tells me how to test for Amps in DC, but not in AC.

How can I check something to get a reading to see if that multitester can do Amps in AC and I'm doing it right?

One thing shot into my mind now. I connected live and put the probe into the water. That was working. Then I connected Live and earth to the probes and submerged them. The power tripped immediately. Live and neutral didn't trip. Doesn' t make sense.

It will not trip because there is no differential between what is going in to what is going out. Else ever thing you use will trip the earth leakage. The leakage has to be between Live or Neutral, to earth.

@Nemos Janitor

Keith, if that is true what you wrote, than Andre is wrong in post 135.

"That is absolutely seriously dangerous shit your doing eish. And that just tells me that there is no tripping protection on your system brother."

So what is it now?

Ok do this experiment and tell us what happens.

Take a 15amp plug and wire up a wire earth to neutral. Plug it in. What happens?

What is a 15amp plug?
 
Nemos Janitor said:
Not always. Wire one up and we will do the next test.

I can do that, but not this time of the day or better night. Might be that my two girls also going to trip, when the power trips.:(

OK the earth leakage will trip depending on some conditions. It will also trip if you wire the plug live to earth. Note you see no sparks and fireworks.

However in the neutral to earth instance, if you unplug all plugs/appliances lights etc that are connected to the breaker then normally it will not trip. There are exceptions.

From this simple experiment we can see that earth and neutral are most definitely NOT the same thing.

Well i won't put my hands in the water until I know what is leaking all that volts in to my tank
 
Hi Guys

I read through this thread today and was both shocked and concerned. I of course know that water and electricity does not mix but never really paid any attention to it until today. My tank is now 4 months old and was started with all brand new equipment. I have always felt that there is some current in the tank when I stuck my hand in the water especially if I have a little nick or scratch on my hand or fingers. Sometimes during the middle of the night when I cant sleep I will go have a smoke in the living room and notice what appears to be a flash in the tank but never paid attention to it thinking that i am halve asleep and imagining things. After reading what happened to Herkie I will be turning all the equipment in the tank off before touching the water but I have a few questions.

1. Someone mentioned emf being produced by the lights. If we had no equipment in the water at all would this still be a concern? So basically if I turned off and unplugged all equipment in the water can I leave the lights on without fear of being electrocuted?

2. If I had absolutely no equipment in the water(which can be achieved at a cost) would electrocution still be a concern or can one work safely in the tank without having to worry?

3. Should we be concerned about the probes attached to controllers to measure temp or ph for instance?

I dont know much about electricity hence me asking the questions. If question 2 is viable then I see a new tank in my near future :thumbup:

1 - EMF is not a problem, as it can't induce a current into the water. If you unplugged all equipment then there would be no risk, however this would have to include your light too, as due to their close proximity they could leak current into the tank via a salt creep path if they were faulty.

2 - Again, this would greatly reduce the risk, however not totally remove it, as I stated, even having electricity near a tank or water involves some risk.

3 - They is always a risk with any electrically operated device that is submerged or had a submerged "attachment", however the risk I would say is extremely remote, provided its a reputable product!

Please understand, I am discussed worse case scenario, however it is possible.
