I'm installing an EasyTouch subpanel next to my pool equipment. Here in the NE, pool equipment tends to be installed away from the house, so typical subpanel mounting on the house isn't an option. The old subpanel is mounted to a 2x6 that is simply buried in the ground. That won't be sufficient for the mass of the EasyTouch panel.
I was planning to bury 2 sections of unistrut (which seems a better choice to bury than wood), and mount the new panel to the directly to the unistrut. But I don't know if that conductivity from the panel to the unistrut to the earth is problematic (potentially setting up the potential for a ground loop?). Is this OK or do I need to "insulate" the panel from the unistrut with plywood?
