 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.
