Hi Richard and group.
ELECTRICAL CONDUIT SYSTEMS IN THE UK.
Electrical conduit systems in the UK were converted during metrication to
their nearest metric equivalent.
Sizes refer to outside diameters
The metric table that Anton provided seems to say that trade size ½ inch
is the same as 16 mm. However, the OD of trade size ½ inch is 20.7 mm, but
EN 60950 says the OD of 16 mm conduit is 16 mm. Obviously, something does
not compute. I hope its not me.

Folks, all of the information on NEMA sizes is moot since the original
question was regarding metric sizes - 16 mm in particular - used in Europe
and most elsewhere

Aren't there any permanently connected ITE equipment mfr's on this

Thanks,

cable
entries, etc. in lieu of a non-detachable power cord for permanently
