Agree. But my confusion back then was between "grounded" & "grounding"

"grounded" carries or at least can carry current in normal operation.

"grounding" only intended to carry current in fault clearing situations, but can be subject to "stray currents" at times.

Not trying to be critical but, it might be worth educating the helper on proper theory of the EGC purpose and connecting it correctly.

yeah, you have electricians miswiring dryers exactly as appliance delivery persons . Doesn't look good.

Usually a google search will also get results from sites and sources referencing the NEC code and what it written in the relevant section one such site is ECM

You need a "slap on the hand" ... You used the wrong term, it should be "Stray Voltage". :)
 
You all are confusing me. A three wire supply to a dryer.
There is no equipment ground.

There is no equipment ground at the dryer

There is a bonding wire/ strap that bonds the non current carring metal on the appliance to the supply neutral/ grounded conductor

An existing 3 wire does not require a GFCI. A new dryer circuit would require 4 wire and a GFCI depending on your code cycle.

Not our intention. We tend to be pedantic in an effort to be accurate.

Just like the service to your house, there is (was) no separate EGC. Everything that needs to be grounded is tied directly to the neutral, which is what you want there to be little resistance to, so a contact by an energized conductor will reliably trip over-current protection.

The old three-wire major-appliance circuits required an insulated neutral or a service-cable style of cable. We just wanted to point out that the neutral was being used to ground the appliance, and that an EGC was not being used to carry the load's neutral current.

It may seem like a distinction without a difference, but there are relevant differences between the requirements for grounded circuit conductors vs grounding conductors. Other than OCP, we basically treat the former much like ungrounded circuit conductors.

Your not looking on https://public.resource.org/ and https://archive.org/details/publicsafetycode?tab=about
public.resource.org recently won a decade long court battle over your right to Edicts Of Government aka statutes and laws including building codes and standards adopted by reference.
The argument is simple "it is the right of all humans to know and speak the laws that govern them"
Once a state adopts a code as law you have a right to know what that law says, for free.

Kind of works both ways.

Since I was initially talking about a grounding conductor that normally doesn't carry current, when it does carry current there is voltage rise on that conductor in relation to surrounding items and a grounding conductor is attached to non current carrying metal items so the rise occurs on those as well. If it isn't a high level of current being imposed on this those voltages can persist where during a ground fault incident it is intended to be a short time event that gets cleared by OCPD.

But yes in a pretty generic sense voltage is needed to cause current.

But, they don't need to make it convenient or easy. Hence, no search function, etc.
