Some say this is safe, others say it's not. I'd like your opinion.


The 3-wire cord (L1, L2 and Neutral) has no ground conductor so it
connects the metal dryer cabinet to your power company's neutral wire.
All is well as long as your power company neutral connection doesn't
fail. If/when the power company neutral fails, the neutral's voltage
can rise to near line voltage which means the voltage on the metal
cabinet of your dryer will rise as well. Obviously an unsafe
condition.

The 4-wire cord (L1, L2, Neutral and Ground) adds a ground conductor
so that the metal dryer cabinet is bonded to your homes ground rod
system. The neutral wire in the 4-wire cable is NOT connected to your
dryer's cabinet. With a 4-wire cord, if the power company Neutral
connection fails and the voltage rises on the Neutral, your dryer
cabinet will remain at zero volts.

So, I guess your 3-wire cable is safe until you lose the power company
Neutral connection...then things become not-so-safe.



I understand, and if I remember correctly, that was one person's comment
on amazon.
