In order to not hijack this thread, I thought I would bring this idea of using the Intex swg copper bars as a waterbond to seperate/new thread.
I was reminded of it when Ohm_Boy mentioned:
Originally I took my copper electrode bars out of the intex swg, but then I had the idea of using them as the waterbond. I put my bars back onto the intex swg but did not hook them up...just observed them over time.Originally Posted by Ohm_Boy
The copper bars have a total surface area of ~12 in^2 (assuming you attach to both of them) so that should meet the minimum 9 in^2 in NEC 680.26. However, somewhere I have read that the conductor needed to be corrosion resistant such as stainless steel or aluminum. My copper bars appeared oxidized (were not bright copper if I remember) when I bought the swg and then over time in contact with the pool water get that green/blue covering in some places which I have read is copper carbonate, copper chloride and/or copper sulphide. All of this does not seem to lead to corrosion in the classical sense, but I wonder if it meets the requirements.
I have probed between the SS (I think) connections and the bars with my RS ohmmeter. There are a number of different looking surfaces I find on the bars, some having ~ 1 Mohm resistance and some having ~1 ohm resistance. The green/blue surfaces seem to have a resistance in the ~ 500 ohm range until you break through it (it seem to be almost a flake above the surface). In the end, I wonder if this meets the functional requirements of the getting a good bond.
I also wonder if there is a small potential on them due to equipotential, if that might cause "corrosion" or loss of copper.
Here are some pics of my electrodes:
