2. When I opened my electric dryer after swapping it for a natural gas
heated dryer... I noticed that the ground and Neutral wires
were connected together inside the dryer. This was not a mis-wiring, as
the factory wiring was designed to connect the ground and Neutral
together... Strange...
In theory, the NEC, UL, and other safety regulatory agencies make
decisions based on sound engineering and safety. In practice, they are
as political and bribe-able as anyone else.
When I worked for Robertshaw and was much closer to the regulatory
process (they had employees on the regulatory boards) I saw clear cases
where the regulations were "bent" to favor things that industry wanted
to do to save money.
Ask yourself why toasters only have 2-wire cords, have exposed
un-grounded metal parts, and you can easily touch the "live" heating
wires and be burned or shocked. They are often used by children, and
start hundreds of house fires every year. Yet they all get UL listed.
None of this would be allowed in anything else!
