I can't see any need to use hardware to hold the cords together. When separated, no hazardous parts are accessible and of course the EUT doesn't need to be earthed when its mains supply is disconnected. With best wishes DESIGN IT IN!

Are you able to use hardware to hold the two power cords together? I would expect this to be required to meet the protective earth requirement for 60950 Section 3.2.5 Power Cords since you are working with a detachable AC mains configuration, though I don't have standards handy to reference the potential country-specific requirements. Regards, Adam >From UL 60950 3.2.1.1 Connection to an a.c. mains supply For safe and reliable connection to an AC MAINS SUPPLY, equipment shall be provided with one of the following: NOTE In many countries, it is a legal requirement to provide a plug that complies with the national wiring rules. – an appliance inlet for connection of a DETACHABLE POWER SUPPLY CORD; 3.2.5 Power supply cords 3.2.5.1 AC power supply cords A MAINS SUPPLY cord shall be of the sheathed type and comply with the following as appropriate: NOTE 1 There is no limit on the mass of the equipment if the equipment is intended for use with a DETACHABLE POWER SUPPLY CORD. • for equipment provided with a DETACHABLE POWER SUPPLY CORD, be not lighter than light PVC sheathed flexible cord according to IEC 60227-1:2007 (designation 60227 IEC 52); – other types of cords may be used if they have similar or better electro-mechanical and fire safety properties as above. NOTE 3 Where national or regional standards exist, they can be used to show compliance with the above paragraph. For equipment required to have protective earthing, a PROTECTIVE EARTHING CONDUCTOR shall be included in the MAINS SUPPLY cord.

I don't think they carry part numbers for all of the countries that David mentions for mating with a C16 inlet ("notched C15" is the description on their site), but definitely worth a good look.

The C-16 inlet is used for 15A cables for North America (120Vac). For countries that use 230Vac, we have been trying to locate power cords with keyed C-15 plugs with little success. Someone has asked if we can use a C-14 to C-15 adapter cable, to allow connection of standard C-13 power cords. The adapter cable has CE, UL and CSA approvals, and is rated at 15A 250Vac. You can see a spec here: <http://internationalconfig.com/documents/98715X3FT.pdf> http://internationalconfig.com/documents/98715X3FT.pdf I know next to nothing about power cord requirements. If we use a country-approved power cable and this adapter, would we comply with local requirements? In particular we are looking at Europe, Argentina, UK, Australia and Switzerland.
