I need to attach a ground wire for a low voltage cable with a small spade connector to a ground point. Does anyone know if there is an available screw or attachment point on the rear of the P10? I could not see one. I saw two screws on either side of the IR jacks and the card reader. They might work if the chassis and case truly were grounded. I presume they are grounded. Does anyone know for sure?
You can use the center screw on the wall plate the P10 plugs into as a ground attachment. This is equivalent to connecting directly to the ground plug unless you are using an isolated ground receptacle and a true isolated branch feeder with an extra ground conductor routed directly back to the serving panelboard. Lots of isolated receptacles installed in this world but few properly connected with a dedicated, Isolated ground conductor. Also, the triangle identifies an isolated ground outlet, not the color orange.
