Commando Industrial Plugs and Sockets
By referring to the chart below, it can be seen that there can be no
interchangeability of products as the earth socket tube is placed in a
different ‘clock’ position according to the voltage and frequency. This
clock position is determined by looking into a socket-outlet from the
front with the key-way at the bottom.
Unless otherwise stated all frequencies are 50-60Hz.
RATING CODE
The rating code which is found on the rating
label of each accessory gives details of rated
current, rated (operating) voltage (or range
of voltages), rated frequency (if not 50/60Hz)
and a symbol to indicate the position of the
earth contact.
(i) For all products (except extra low voltage)
the position given is that of the earth pin
when a socket-outlet/connector is viewed
from the front with the key-way at the bottom.
When viewing a plug/ appliance inlet from the
front with the key at the bottom, the position
of the earth pin is reversed, ie., a 10 o’clock
will appear at 2 o’clock and other positions
are relative.
