1.  Reduce creepage by 1.45 inches (36.8mm) when ordering without insulating bracket.
2.  Weight does not include metal mounting hardware
3.  MCOV = Maximum Continuous Operating Voltage that may be applied continuously between the 
     terminals of the arrester.
4.  The equivalent Front-of-Wave is the maximum discharge voltage for a 10kA impulse current wave
      which produces a voltage wave cresting in 0.5 μs.
5.  Based on switching surge current imulse of 45x90 μs, 500 amperes.
