If I remember correctly, the DC-DC convertors need to be isolated convertors. Regarding the amps, this is difficult to answer without knowing what you plan to run with the convertors.

Hi all, What is the amperage requirements for the 2 sailor convertors, I
need new ones. I'm assuming 20 amps will be plenty and that I can get victron
or master volt ones without any problem.
