I am planning to install a pair of 3600W auto isolation transformers on my USA 115v boat which currently has two 115v/30a shore line circuits to allow it to plug into two 230v/16a or 115v/30a (Using 115v output and allowing for frequency change). However, I’m confused about which ELCI to use, 230v/16a or 230v/32a so that the boat will be protected when plugged into either. Any and all advice is appreciated.
