I'm trying to galvanically isolate a device which is controlled by ethernet (1000base t) via computer. I've been looking and apparently the ethernet standard provides some isolation, but after I connect the cable to my otherwise isolated device to my computer, my multimeter reads short between its ground and earth ground. The #12 is THHN fed via PVC not EMT to the box. I need to add a 3-way switch into this box (part of a 4-way circuit) that is on a 15amp branch that is driven from the subpanel. The new 14/3 romex coming into the box is just runners for the switch - so 3 hots and a ground. This is the outside wall and the back side of the electrical meter panel. The large wire bundle going out of it runs through my attic to my breaker box on the opposite wall. I was wondering the best way to insulate around the box. I planed on using batt insulation and cutting out the space for the box.
