The IEC standard – an overview
Current rating: All IECs are rated up to 250 Volts AC, but are categorised by their current ratings. To prevent potential overloading, they are designed to not be interchangeable between 10 Amps and 16 amps.
10 Amp IECs include the C13, C14, C15, C16, C15A, C16A, C17, C18. These may be up-rated by an approvals body to up to 15 Amps in North America for use at 125V.
16 Amp IECs are the C19, C20 and C21, which may be up-rated to 20A at 125V use.
The 2.5A C7 and C5 connectors are no longer permitted as rewireables, so please see our moulded IEC page for these as mainsleads.
Temperature rating: Standard, cold, or cold condition IECs are rated to a maximum temperature of 70°C, taken at the pin contacts. These are the C9, C13, C14, C17, C18, C19, C20.
10A IECs can be hot condition for use up to 120°C: the female C15 and C16.
The 16A goes straight to very hot condition at 155°C for the C21, and the 155°C 10A are the C15A and C16A. The higher temperature IECs are made from heat resistant thermosetting plastic and have slightly modified profiles to prevent lower temperature rated connectors from being used.
Cable entry: All Morvan stock IEC connectors are straight as standard, but we also offer angled cable entry. 10A plugs and connectors are available as right angle, left angle and bottom angle, while the 16A versions can be right angle or left angle.
