Without such a background, a do-it-yourself homeowner might be prudent to hire an electrician. To gain access to one of my main panel's knock-outs, so I could install a 1/2" X 3 1/2" conduit nipple between the two, I used a hole saw to create an opening through a wooden stud. That required a right angle drill because a conventional drill would not fit into the 6" square opening required for the Panel Protector. The knock out on the electric panel, of course, needed to be exactly aligned with the knockout on the panel protector. Careful measurements are important. Installing the conduit nipple between the two metal cabinets, required lock nuts and bushings on each end before threading the wire. Using metal conduit between my panel and this device helps to enhance ground continuity in addition to the green grounding wire. The extra grounding should improve protection. Instructions with this surge protection unit suggests connecting it to the panel through a two-pole 20-amp or 30-amp circuit breaker. My choice was a 30-amp breaker which calls for #10 copper wire. I used THNN wire for the connections, which included L1 & L2 hot wires, a white neutral and a green grounding wire. A DEWALT Impact ready right angle attachment to my impact tool enabled me to use screws to mount and secure the panel protector to the wooden stud. Turning on the breaker illuminated the two green lights on this device showing that it is actively protecting. I'm optimistic that this surge protection will be effective for our home, which has had some power surge issues in the past.
