[BC] Fused plugs - was Hot and grounded chassis

[Gordon Carter]

Sure, that's what the CURRENT standard is, but to someone growing up in
the late '40s and '50s there WAS a difference.  Those plugs and outlets
were distinctly NOT polarized.  Both blades and holes were equal.  I can
remember when we first got plugs with the polarized blades (one bigger
than the other) that they would not fit in the outlets in our house.

It is easy to find fault when you base old practices on current
standards.  Typically the newer standards are more stringent than the
old ones, since they have evolved from flaws in the older standards.

A NEMA 1-15 receptacle has a large pin and a small pin.

The large pin is neutral/grounded conductor; the small pin is line.

I believe those double-fused plugs were made with two small pins.
