Does a typical Surge supressor (power strip) need a ground to operate properly?
In other words, if it is plugged into a 3 prong (grounding-type) Receptacle, but there is no grouind (only 2 wire) will it work and protect from surges?
I know I'm no expert on these, but I seem to remember that they do indeed need a ground to work. They shunt the overvoltage to ground, not the neutral.
