Hi Mark:
I understand that the equipment in question is a direct
plug-in device. It includes a socket-outlet that is
the same configuration as the socket-outlet in the wall.
I understand two questions:
1) Should the rating of the equipment be included?
2) How should the socket-outlet be rated?
In answer to question 1: Yes, the rating of the
equipment must be marked on the unit, e.g., 0.1 A.
This is the current when nothing is plugged into the
included socket-outlet. (The plug configuration
identifies the total current of the equipment and the
included socket-outlet.)
In answer to question 2: The rating of the
socket-outlet must be marked on the unit. However,
the sum of the equipment rating and the socket-outlet
rating cannot exceed the rating of the equipment plug
(which should be equal to the rating of the socket-
outlet on the wall).
If your equipment is 0.1 A, and if the equipment
provides a British standard 13 A socket-outlet, then
the socket-outlet must be marked as 12.9 A or less.
I understand a third question:
3) Can a stand-alone socket-outlet be rated less
than the rated current for that (standardized)
socket-outlet.
In answer to question 3: A stand-alone socket-
outlet must comply with the national standard for
that socket-outlet. However, if the socket-outlet
is mounted on an equipment (by which it is no
longer stand-alone), the socket-outlet can be
marked with a rating that is less than the national
standard for that socket-outlet.

Subject: Socket-outlet current rating on the direct plug-in equipment
Hi,
if one to sell direct plug-in equipment with build-in socket outlet
(air-freshener, night light) what would be appropriate current rating on the
socket? Do you have to take into consideration current draw of the product
itself, regardless of how small it could be, let's say 0.1A?
For example, UK version, based on BS1363, maximum current is 13A. Do
you put
12.9A on the socket? and if yes, how practical is it to expect the consumer
will follow it to the dot?
In general, can standalone sold sockets be rated less than maximum
allowed
current in each country? do you ever encountered such sockets?
Thanks for the inputs any of the above,
Mark
