I've been reading this entire thread for the last few days. After a while I would glance over the responses by some members as you could tell exactly what they were going to say. I appreciated the links to the IEEE guide on Surge Suppression and to Solving ground loops as well as others. I also enjoyed the Youtube videos of the SurgeX guy destroying their competition literally. Before reading this thread I had already installed an Eaton CHSPT2ULTRA device in the main electrical panel. I also installed a Midnite Solar MNSPD300-AC device on the PV Combiner panel just before the Solar generated AC back feeds into the main electrical panel.
For the house, I have been using a mixture of MOV based devices from CyberPower, Triplite, Belkin and some lesser brands purchased at Newegg. At first I was seriously considering the APC P11VNT3 but there was an issue with the value of the L-N, L-G, N-G UL 1449 Type 3 SPD voltage protection labeling on the device. APC states the voltage is 330V yet mine read 400V, 500V and 400V. So I opted not to go with this particular APC device. The Belkin BE112230-08 states UL Clamping Voltage (3-wire) UL1449 500V. It was through this thread that I found a link to a recall of nearly 15 million surge suppressors and had some that were on that list. I also found a link that suggested that the MOV based search suppressors be shook (lightly) periodically to see if there is anything rattling around. Sure enough 3 suppressors were rattling and in one all the MOV's were no longer connected on both ends, yet the indicator light was still on indicating that the device was functioning.
I had given serious consideration to the Furman PST-8 and PST-8D surge suppressors. What intrigued me the most was their ability to shut the device (and anything connected to it) off once the voltage hit 145 VAC. What disappointed me was that they still used an MOV device (at least one that they mention and can be readily seen in a photo of the circuit card).
Earlier this year we cut the proverbial cable cord and in designing my grounding system, I went with the Morgan Manufacturing M315 UHF/VHF/CATV arrestor which employs "a hybrid circuit of both gas discharge device and metal oxide varistors for fast attack speed, DC voltage passive up to 50 volt". This is a leg up to the TII Tech 212 device gas-discharge only tube (which I also left in the box for a future Satellite dish). Cables are also connected to a grounding block terminal & the antenna mast is grounded as well as all ends of the EMT. The box was placed over a hole in the side of the house where the builder left some quad shield RG-6 cables. I use a power inserter in the house where the cables come in to deliver power to the Winegard mast mounted pre-amp. Without it, I could only pull in 3 channels. With it more than 88 some over 130 miles as the crow flies. I ran a #4
gauge wire from the box to a new 8-foot buried ground rod which is connected to the main electrical service ground via a 100 feet of #6
gauge solid copper wire to a depth of 18" and making a half circle pattern (i.e., no sharp 90 degree turns). The telco connection at the side of the house has been disconnected at the NID since we no longer use a land line from the phone company (we do love our Ooma VOIP service). The cable guy was out at the house recently and installed a grounding block at the demarcation box, stating the code had changed from when the house was built to where its at now in 2015. The ground block also terminates to the main electrical panels ground rod.
There really is no need for further coaxial cable protection in the house or for telco protection (for us). The NID is also grounded to the main ground rod so even with a telco connection I still would have no need of further filtering or surge suppressing for it in the house.
I also looked at Series Mode devices from Zero Surge, Brickwall (which is a Zero Surge Private Label and made in the same factory as the Zero Surge devices). There is a reason that the products from Zero Surge and Brickwall look very much a like. Brickwalls products were more expensive, even with their 10%NOW coupon. Zero Surge is also offering a 10% off coupon on additional orders placed within 60 days of the first order. The Zero Surge representative mentioned that many of their units are still working after 25 years and some customers have sent them back to be re-tested and none have failed yet. You can find bargains on eBay for the Zero Surge, Brickwall and SurgeX devices.
In the end I went with SurgeX opting for 7 of their SX-1115 devices and 2 of their SA-82 devices. I have a detailed spreadsheet that I used to note the max watts/amps for all the devices that will be plugged in and to which device. I also added typ(ical) columns and observed columns. The Monster HTS 3600 looks nice and has a useful voltmeter and ammeter on it but I double checked everything with a Kilo-watt meter as well. In no case will I ever approach 70% max power and I can't imagine being in the room without heavy ear protection at that volume level. I have equipment throughout the entire house and the SX-1115's fit the bill nicely. Down the road I will build a nice 1U and 2U racks made out of wood for these devices but for now, little rubber feet will have to do.
I want to thank this forum for their contribution in helping me understand. You're all a bunch of swell people. Just thought I would share what I learned and what I ended up doing.
