Hi I'm working as an electrician doing installation on ships etc. When we're testing generators we use a thub with sea water in it and 3 copper tubes connected to the three-phase 230v system. We're gradually lowering the tubes into the water which results in a increase of current flowing. No problem to pull 300++ amps. My question is, are there any chemical reaction happening when applying 3phase AC current to sea water like that, or will the water just boil?
