Help Electronic gurus, IEC Questions for upgrade

Thank you kindly, intersting but after researching a little I saw under neutrik this lable under the PowerCon.
Read the last paragraph, does this mean I am unable to use it for my 50w integrated amplifier's main connector????????

PowerCon® is a lockable 3-pole equipment (AC) connector with contacts for line, neutral and premating safety grounds. Color coded for easy identification, PowerCon® offers power-in (blue) and power-out (gray) versions with different keying to avoid the possibility of short circuiting. The contacts are designed to prevent damage from arcing when disconnected while under load. PowerCon® meets or exceeds the demands of applications in the fields of A/V usages, test and measurement equipment, computers or industrial designs. UL recognized, SEV and VDE approved. Rated at 20A/250VAC.

• Connector: PowerCon® chassis connector • Type: Power In • Color: Blue (A) • Mfg. #NAC3MPA

Note: PowerCon® is not designed to be a "mains" connector or for speaker/amplifier applications. For speaker applications please see the Speakon® series.

The only connector that might meet your requirements would be the Neutrik POWERCON. The connector is round and the recepticle is somewhat smaller than a standard IEC.
