ProMariner makes a nice 60 Amp Isolater that can be used with one 50AMP line, or two 30amp lines - sells for around $300 on sale. Not sure if running two 30 AMP lines would combine neutrals - will have to check that out. But I run one 50amp line, so this looks promising. Anyone have experience with this ProMariner product?? :thumb:


This is a nice product, and will do a good job at what it is intended for (i.e. a barrier to DC leakage path), but it will not solve any of the problem of neutral-to-ground issues, or co-mingled 30 amp neutrals. It is totally different than an isolation transformer.
