What does a homeowner need to know about residential electrical systems?
One hundred percent copper wiring is ideal wiring
material for home construction. Special electrical
receptacles -- ground fault interrupters (GFI) -- are
placed in all bathrooms and on the home's exterior. The
GFI trips the breaker in 1/200 of a second to ensure
instant and total safety in case of an accident (i.e., a
dropped hairdryer or electric shaver in a sink of
water).
