[Elecraft] [OT} Whole House Surge Protection

[David Cutter]

These were very popular in Kenya where black-outs, drop-outs, brown-outs, 
high surges
and spikes were common:

Many fridges, freezers and all household equipment is saved using the 
plug-in units.  It was typical for the mains to read 400V (240V nom) when 
the power returned after a drop out and the little units would just hold off 
the load till those passed and a timer dropped back on.
