It was never really a phobia (pathology) but a rejection of everything that was electric. It was a type of neophobia in the late 19th century when electrical-powered artifacts began to appear. Today it is only justified in someone who has received a discharge that left him traumatized.
Electrophobia is fear of emchufes, cables, rejection of electronic appliances may well be air, light, water. . . . . . . .
I hate or reject end to everything either electrical or electronic. Not confused with Alectrofobia which is the rejection or fear of chickens.
