Lets say the first one trips, if the voltage reaches 200
volts. The second one trips if the voltage reaches 200
volts. How would that add up? I say, not at all.


OTOH,if there's enough energy to blow past the first protector,the 2nd will
absorb/shunt it. The 1st protector also acts as a delay,slows down the rise
of the pulse.
