My name is Bob.
I am just now beginning my formal studies in home inspection.
I am working on “How to Perform Residential Electrical Inspections Course,” and I frequently refer to Black and Decker’s Complete Guide to Home Wiring for supplement and reference.
I am not yet 10% into the course and I came across some awkward wording (in the Black & Decker manual.)
It reads “After 1920, most American homes included receptacles that accepted polarized plugs. The two-slot polarized plug and receptacle was designed to keep hot current flowing along black or red wires and neutral current flowing along white or gray wires.”
As I said I am new at this but
I am confused about the idea of nuetrak current flowing.
It seems to me that
-all electrical current us “hot,”
- there is no such thing as “nuetral current,” and
- the phrase “keep nuetral current flowing” is utter nonsense.
as long as nothing connects the hot side to the cold side, no current flows through the cold side at all. Is that thinking incorrect?
I’ve got a second question also, but, one at a time.
