How they differ

IEC 60320 C1 cord connector Identify the exact C1 connector versus its mating C2 inlet from the equipment or cord documentation; do not select, adapt or install a mains-power connection from shape alone.
IEC 60320 C2 appliance inlet Identify the exact C2 appliance inlet versus its mating C1 connector from the equipment or cord documentation; do not select, adapt or install a mains-power connection from shape alone.

USB-C vs USB Power DeliveryConnector shape and negotiated power are different layers. A USB-C port does not by itself establish a particular USB Power Delivery capability.IEC 60320 C15 versus C15A connectorsIs the cord connector C15 or the distinct C15A very-hot-condition form? Similar naming is not permission to substitute or modify a mains cord.IEC 60320 C16 versus C16A inletsIs the appliance inlet C16 or the distinct C16A very-hot-condition form? Similar naming is not an installation or substitution verdict.IEC 60320 C19 versus C21 connectorsIs the cord connector C19 or C21? Both occur in the higher-current IEC 60320 family, but exact configuration and equipment requirements remain separate.IEC 60320 C20 versus C22 inletsIs the appliance inlet C20 or C22? Exact configuration, equipment rating and approved cord set must be resolved from equipment documentation.IEC 60320 C23 versus C24Is the part the C23 Class II connector or C24 inlet?
