R27 Galvanic Isolator

[Rtug]

Does anyone have advice on how to install a galvanic isolator in 2019 R27? What's the best location to mount unit and splice the ground wire? Video or photos would be great. The corrosion on lower unit is bad.

This is a video I made for the R43, I imagine the general install should be similar. Probably don't need the higher amp rating.

Just under the breaker panel, on the carpeted / insulated nook just below.

Make sure you get a failsafe version. Older models (even some still sold) have a nasty fail condition.

The installation itself is pretty easy. Just make sure you have proper crimping and cables, preferably to ABYC standards. I'll be honest, despite being an easy one -- I hired someone to do it. I promised the Admiral I'd never play with AC mains again. 🙂
