P551/2 Connectors

Description | Applications | Pin Assignments | Assembly Instructions

Description:

A mains rated (6A) 8 pole connector commonly used in lighting applications. It is keyed so it can only be inserted one way around. Both the plug and the socket can be live when un-mated, so the connector can be used for mains input and output, e.g. daisy-chaining disco light boxes to one controller. A newer 10A range is available including a line socket and panel plug.

Typical Applications:

Disco and Stage lighting (up to 5 live + 2 neutral + earth).

Any other application requiring a multi-pole mains connector.

Pin Assignments:

For disco and stage lighting, the standard pin assignments are:

Pin 1 (centre): Earth
Pin 2: Channel 1
Pin 3: Channel 2
Pin 4: Channel 3
Pin 5: Channel 4
Pin 6: Not used, or permanent live
Pins 7 & 8: Neutral (connected together at plug & socket)

Note that multicore cable used to connect P552 Plugs MUST have a larger neutral wire, since this takes the load for all 4 channels. Each pin in the connector is rated at 6 amps, the neutral is shared between pins 7 and 8 to give 12A capacity. THE TOTAL LOAD ON ALL LIVE CONDUCTORS MUST NOT EXCEED THE RATING OF THE NEUTRAL CODUCTOR.

Connector Assembly Instructions:

The plug has solder or screw terminals. Ensure the cable is clamped under the cord grip - the entry hole is big enough for several mains cables or one 7 core cable. The cover screws on after the wiring is complete. The panel socket has solder terminals.
