A surge-protected outlet strip should be fine. Supposedly, a really bad surge will either pop the circuit-breaker in the surge-protector, or your electrical panel before the surge-protector itself gets damaged thereby leaving your clock unprotected.
If your clock uses an external power supply, then the worst-case scenario would likely be that the power-supply gets fried rather than your clock, and that is unlikely. 800 joules is a lot of energy; I read somewhere that most surges at residential outlets are less than 100 joules so paying for a 3840 joule protector is probably a waste of money unless you have frequent nearby lightning-strikes that hit your power-lines. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
