Hi all, I have a dedicated network DMARC in my house with a 12U rack and separate coax distribution. I plan to install outdoor PoE cameras in the very near future and want to make sure I do my diligence in protecting the equipment BEHIND the cameras. I understand the typical setup is getting a Grounding Bus Bar and connecting the equipment or racks to the bar and then likewise connecting the cameras to a Ethernet surge protector (with shielded CAT6) and ground the ethernet Surge protector to the bus bar. My question is with the bonding of the bus bar to an earthed ground...How do I accomplish this? Is it sufficient to use a copper pipe clamp and clamp a ground wire to the copper plumbing coming in to my house? Or am I forced to bring the copper wire to the electrical panel's grounding bus? On that same note, if clamping it to plumbing is acceptable, is it OK to run the ground wire (with a PVC jacket) in plastic wiremold that it also housing Ethernet cables into the Utility room where the copper plumbing is? My route to get to the attic goes through my laundry/utility room. I already have wiremold in place to get the Ethernet cables there...I just am not sure if I'm allowed to run the ground wire, again with a PVC jacket, through the same conduit. Any advice is greatly appreciated! John

Hello I thought I maybe knew the answer to this but just to get clarification. I bought a couple aquarium heaters from eBay and some come even with North American style plug even. However I did not notice they are 220v 50-60hz. I know that's mostly European and Asian voltage but will they work here in North America. mine seem to heat up but my assumption is that even fully cranked to high temp setting they will only heat at about half temp or less. Would this be correct
