Hello,
We are looking for a wiring schematic that details the installation of two VE 7000watt 230v Isolation Transformers, one on each shore-connection power inlets. Does anyone experience with this type of installation and are willing to share or can point us to technical literature that cover separately derived power sources?
The main use-case is to spread the load across the Shore-1 and Shore-2 inlets. In general, Shore-1 feeds the boat's AC electrical demand and Shore-2 feeds the boat's air-conditioning systems.
Each show-connection inlet will feed into a two-pole breaker, then into the Isolation Transformers, and into a Blue Sea ELCI Main circuit breakers and then on to the boat's electrical panel. At the panel are other RCCB breakers. We have wired the first unit according to the U.S. ABYC standards and everything is working as expected.
One of our pressing questions is how to tie in the neutrals with grounds on the boat when there are two isolation transformers to avoid nuisance trips of the RCCBs. As of now the plan is to tie into each isolation transformer separately. Is this the correct thinking?
We are doing a refit on an Oyster 66 sailboat here in the U.S. We want to make sure we are adhering to the ABYC standards but can't any details that cover this configuration.
Can anyone point us to information that addresses this?
