The best is just good wiring and a clean ground. Next is a sacrificial circuts like are used in the lightning protection for my base station antennas.
If the resistance between two fillaments is lower for a high energy than the electrical circut that is being powered the energy chooses the lower resistance to ground. As long as the common 120V does not have the potential to jump the gap, or complete the same circut it. It becomes a effective lightning, or surge suppressor.
A computer wiring is a bit different than thick copper coils in a transformer. .5 more volts to a CPU can kill it.
“it would have been perfect....its got trains and the line"tech your kids not to do what iv done"(or similar) because i had obviously done something to warrent 2 e-thugs to come 4000miles out of their way and kill me.” -Solaris17
“yeah i failed. i noticed the "coming soon" part after i posted.” -Mussels
Yes I am evil, yes you can have some.
