And, why didn't it trip my breaker?? So, that has been my morning. Thought I would share
It may be that most 20AMP house main breakers will not trip if the short is from a fair volume of water as it won't place enough load on the system, but rather make the tank act like a big heater core or a light bulb. (like a resistor but not enough to be a short?)
I actually tested the house breaker with same salt water from the tank placed in a bucket of water, and ran two sides of the AC cord into it. The bucket absorbed the electricity and breakers did not trip. I then changed the main breaker to the line with a 15AMP and still it didn't trip it.
(a dumb experiment maybe, and dangerous if not done with proper precaution but I simply wanted to know with worst case scenario being imminent at any given time with things like a reef tank...)
So anyway, knowing that... I re-installed the 20AMP as designed for the house line as per blueprint of the house, so as not to trip it with a vacuum cleaner or other devices on the same line. Rather I installed a second outlet with a GFI protection next to the existing standard outlet, and anything that hangs over the tank like lights, and submersed like a pump, I rerouted them through the GFI outlet. I can use a power strip or a protected UPC device as well for back up, which is my next plan for pumps at least.
Stay safe out there everyone! At close to $150 a month of electricity a month, the current draw of a big reef tank is no joke
