50A surge protectors
I see surge protectors for from $100 to $500 +. What makes one better than the other?

I was full time up to one month ago. I never needed a surge device--but used the autoformer 9 times out of ten.
Autoformers are especially useful in winter time so that the full wattage on electric heating becomes available.
Here is an example:
power 750 watts at 120 volts (120 x 120)
power at 100 volts (100 x 100)
750 X .6944 ~= 520.8 watts
That makes a huge difference of slightly over 30% more power at the correct voltage. Since I generally heated 100% electrically this was important. My peak load was 7000 watts and the average about 5200 in the dead of winter.
