A:Answer Dear A. Nonny Mouse, The surge protector protects against energy surges, not a specific maximum ampere electrical current. The device protects against an energy spike of 1030 Joules. One Joul is the equivalent of one watt-second, or the energy of one ampere of current passing through one ohm of resistance for one second. I am sure I left you completely confused. A surge could be hundreds of volts for a fraction of a second which means for 1030 Joules, the current could be a few amps to hundreds or thousands of amps. Remember that in order to have current flow, one needs voltage forcing the current, just like water needs pressure to flow. Hope that helps.
