Peter, In a past life, I had control of a screen room with double screened walls. The manufacturer had specified connection of both screens at a single point to a dedicated ground rod. But, it was originally connected to ground via the electrical conduit of the power mains due to economics and location at the time. The shielding integrity of the screen room was checked and found to be quite good. BTW, the power supplied to the screen room was filtered at the screen room. The screen room was eventually moved to another location where grounding was obtained via a dedicated ground rod. Shielding integrity was checked again and found to be still quite good. So, I believe that such grounding is acceptable provided it is reliably connected and secured from mishandling. At least from my expereince, such ground connection schemes appeared to make little difference in the shielding integrity of the screened room. Perhaps this was due to the characteristics of a Faraday cage. Anyway, your experience may provide different results. Good luck. Best regards, Ron Pickard ron_pick...@hypercom.com
