    Hum… I have 75MJ varistor on each phase of the main wiring of my house. Those are not fuses (because fuses don’t have a total energy ratio) but I can certainly get a few more for the Enterprise it they want.

        Yes, I’m sure. I used to have 5MJ ones, but one burned down once. So I got the large ones. AFAIK, they are the largest that will fit 1 unity in a DIM panel. It’s supposed to change phases more than once if it receives that kind of abuse, but keep safely conducting electricity all the way.

        It’s a common component around lightning protection. You’d want something better to actually deal with the lightning if your network is unprotected (there are plenty of options), but mine is protected.
