About Electrical Wiring EMF

  • -Every home and building contains miles of electrical wiring hidden behind walls, under floors, and above ceilings.
  • -This wiring carries alternating current (AC) electricity at 50-60 Hz, creating extremely low frequency (ELF) electromagnetic fields that extend into your living spaces.
  • -While you can't see these fields, they're present wherever electricity flows, and unlike many EMF sources, electrical wiring operates 24/7 in virtually every indoor environment.
