Commando plug to IEC C13 socket lead

M. Joshi
I have seen leads made up with a Blue Commando plug at one end and an IEC C13 single socket/PDU (or UK plug socket) at the other.  Given that the IEC C13 socket is only rated to 10A, I assume one is reliant on the supply from the Commando socket having appropriate overcurrent protection?


To give some context, I need to provide a supply to an industrial control enclosure which has a fused IEC C14 inlet.  Beyond the inlet, the supply inside the enclosure is protected by a 10A fuse.  I do not have the ability to specify the overcurrent protection at the source (Commando socket) as this is supplied at the location as is. 


An alternative may be to use an IEC C20 inlet on the enclosure and fuse down internally however, there isn't much space left on the DIN rails.


Can something like a Schneider 13956 mini enclosure be installed inline with the supply cable (between the Commando plug and IEC C13 socket), with an overcurrent protection device installed in the mini enclosure?


Thanks.

    Thanks again Mike for your detailed reply.


    The excess cable will be managed and cable guards used where it is likely to be walked over so, there is minimal risk of damage to the cable.  The only risk might be if the cable hasn't been terminated properly on the plug and socket at either end of the cable however, a direct short should trip the upstream overcurrent device as you say.


    I do intend to specify an RCD as I am not sure if the Commando socket is protected by one.


    Do you know if there is a latching inline version of the one that you linked to?
