Is there a EU-wide convention for the marking of
terminals in a single-phase appliance?
It is understood that the PE terminal must be marked or
identified with the green-yellow color, but is there any
expectation or requirement that "L" and/or "N" be present?
What if only "L" was present? only "N"? neither? Is
there any objection to marking both "L" and "N"?
In the risk assessment for a hypothetical device, no
additional hazards are created during operation if the live and
neutral lines are switched. One could argue that a service
person would rely on the "L" or "N" or similar marks in order to
know which lines were potentially live, if the appliance was
connected to power for troubleshooting, but IMO, competent
service people would not endeavor to work with a conductor unless
they were certain it was not live.
