It wasn't aimed at you Don.
I fought ROTE ignorance for my entire career, flooded lead acid batteries and DC alternator design. Folks who read books and then parrot whatever they read are like my Dr. who insisted I receive blood thinners BY ROTE and damned near turned me hemophiliac. Utter, blatant, and somewhat arrogant rote reaction.
I have time to build an eight dollar circuit to protect $500 worth of IC controlled appliances. What I do not have is the $500 to replace them because ROTE blathering says I do not need transient voltage protection. I can ID a rote spewer within a couple of minutes because they love to camouflage lack of experience with a blanket of spurious claims not specifically directed at a concise subject target. Talk about transient events, they blather long term "surges" of over-voltage. Talk about enhancement of lightning ionization pathways (at the power pole) and the next thing you know they'll have your gas discharge tube device inside your coffeemaker.
The idea is to gain a product that commercial enterprises find to be horribly confused with a POS power strip. Constructing a PROPER transient diversion device (It cannot "absorb" events - it diverts them) can be obtained in $200 - $300 DOLLAR specialty devices. If these devices were fraudulent the companies (Try Tripp-Lite) would have long ago gone out of business. And like it or not, MOVs degrade. All devices DEMAND individual component safety fusing. Something easily done on a hobby bench but horribly expensive to design, UL ETL or CSA certify, market and distribute. Pay $300 for eight dollars worth of discrete components? Makes perfect sense to spewers of shotgun grade ROTE. I've zero time to deal with misdirected nonsense.
Add MOVS. Use eight devices per route (Line to neutral line to earth ground). Multiply TVS total devices. Share the load. Lengthen suppressor lifespan.
Don, your math is impeccable and irrefutable for your situation. Good job.
