NAC3FCA / NAC3FCB 3-Pin Powercon Stage Lighting Connector – Blue (Input) & White (Output)

Powercon connectors (NAC3 series) are the professional standard for mains power connections on stage lighting fixtures, PA amplifiers, and touring audio equipment. Developed by Neutrik, the Powercon design provides a twist-lock mechanism that prevents accidental disconnection under load — a critical safety feature in live performance environments where a kicked power cable could cause equipment damage, audio dropout, or safety hazards. The blue (NAC3FCA) and white (NAC3FCB) color coding distinguishes input (blue, power in to equipment) from output (white, power out / loop-through) connections, preventing incorrect daisy-chaining.

NAC3FCA vs NAC3FCB — Blue vs White Explained

• NAC3FCA (Blue — Input): Power enters the equipment through this connector. Blue = power coming IN to the device.
• NAC3FCB (White — Output): Power exits the equipment for daisy-chaining to the next device. White = power going OUT.
• Critical rule: Blue connectors only mate with blue; white only mates with white. Different keyway positions physically prevent cross-mating — a blue plug cannot be inserted into a white socket. This prevents reverse daisy-chaining which could damage equipment.

Powercon vs IEC C13 vs Powercon TRUE1

• IEC C13/C14: Standard equipment power connector. Not locking, 10A rated. For office equipment and static installations only.
• Powercon NAC3 (this product): Twist-lock, 20A rated. For touring and live performance. NOT hot-pluggable — de-energize before connecting/disconnecting.
• Powercon TRUE1 (NAC3MPX/NAC3FPX): Newer standard. Hot-pluggable (safe to connect/disconnect under load). Required for applications where live connection is necessary.

What Questions Does This Product Answer?

• "Can I connect Powercon NAC3 under load?" — No. NAC3FCA/FCB are NOT rated for hot-plugging. Always de-energize the circuit before connecting or disconnecting. For hot-plug capability, use Powercon TRUE1.
• "How many devices can I daisy-chain?" — Total load of all daisy-chained devices must not exceed the circuit breaker rating (typically 16A or 20A) AND the 20A Powercon connector rating. Calculate total wattage ÷ mains voltage = total current.
• "What wire gauge for Powercon cables?" — Up to 10m at 20A: 2.5mm² (13AWG) minimum. 10–30m: 4mm² (11AWG). NAC3 solder cups accept up to 4mm² per contact.
• "Are these Neutrik-compatible?" — These are Neutrik-compatible NAC3FCA/FCB connectors. They mate with genuine Neutrik Powercon cable connectors (NAC3MCA/MCB). Verify physical compatibility before use in critical touring applications.

Typical Applications

• Stage lighting: Moving head fixtures, LED wash lights, Par Can power, dimmer rack outputs
• PA systems: Power amplifier mains connections, powered speaker inputs, subwoofer power
• Touring audio: Rack-mounted equipment power distribution, stage box power connections
• Install audio/AV: Fixed installation amplifier racks, AV equipment rooms, permanent stage installations
