Transient Voltage Spike Protection Home Made Device

My opinion is that 104 volts cut out is about 3 volts too low. I.E. it should cut out at 107 volts, not 104.

Since I'm far more likely to find low voltage, an autoformer would be much better for me--with Mex's surge device between the autoformer and the pedestal.

My Progessive unit also protects the electric units from low voltage which will burn out any appliance if left on with low voltage. So I have high and low and miswired connection protection. Some things are worth the cost.
