powerCON TRUE1 Cables: The Stage Power Standard for Touring, Rental, and Live Events
On any professional stage, the cables carrying mains power look almost identical to the ones carrying audio. That is exactly why the entertainment industry standardized on powerCON connectors: they are impossible to mistake for a signal connector, they lock, and they carry real current safely through years of load-in and load-out abuse.
This guide explains the powerCON family — TRUE1 vs TRUE1 TOP, NAC3FX-W vs NAC3MX-W — and how to spec stage power cables that survive touring.
powerCON family: which connector do you need?
The powerCON system comes in two generations:
| Connector | Type | Rating | Hot-plug safe? |
|---|---|---|---|
| powerCON (NAC3MPX / NAC3FPX) | Power only | 20 A, 250 V AC | No — must be powered off |
| powerCON TRUE1 (NAC3MX-W / NAC3FX-W) | Power only | 20 A, 250 V AC | Yes — make/break under load |
| powerCON TRUE1 TOP (NAC3MX-W-TOP / NAC3FX-W-TOP) | Power only | 20 A, 250 V AC | Yes — plus weather-protected top cap |
The “TOP” variants add a rugged top cap that protects the contacts when unplugged — important for outdoor stages and festival environments where connectors sit in dust and rain.
TRUE1’s key advantage is hot-plug capability: you can disconnect a live device without arcing damage, which is essential when a sound engineer needs to swap gear between sets without powering down the distro.
Male vs female: NAC3MX-W and NAC3FX-W
- NAC3MX-W — powerCON TRUE1 male (cable mount, power source side)
- NAC3FX-W — powerCON TRUE1 female (cable mount, device side)
The naming is confusing because the gender convention is the opposite of IEC: the female (FX) is the power-INPUT side used on devices, and the male (MX) connects from the distribution. When building a cable, you terminate one end with NAC3MX-W and the other with NAC3FX-W, then power flows from source to device.
powerCON vs powerCON TRUE1 vs IEC: which to use
| Use case | Recommended |
|---|---|
| Rack power, PA systems, dimmer packs | powerCON TRUE1 (hot-plug, locking) |
| Touring cable looms (source to distro) | powerCON TRUE1 TOP (weather cap) |
| Studio / fixed install where gear is rarely moved | IEC C13/C19 or standard powerCON |
| LED wall processors, monitors | IEC C13 (standard device inlet) |
A typical stage power cable kit includes: TRUE1-to-TRUE1 looms (power between racks), TRUE1-to-C13 breakout (powering monitors and processors), and C13-to-C13 jumpers. If your fleet mixes old powerCON and TRUE1, verify every cable’s connector type — they look alike but must not be mixed on live circuits.
Specifying stage power cables
- Conductor: 1.5 mm² (16 AWG) minimum for 20 A touring cables; use 2.5 mm² for long looms
- Jacket: H07RN-F rubber (oil, abrasion, and weather resistant) for touring; PVC acceptable for fixed install
- Length: 1.5 m, 3 m, 5 m, and 10 m are the workhorse lengths; color-code (e.g., black = power in, blue = power out)
- Termination quality: crimped and soldered connections, strain relief on both ends — a loose termination on a 20 A circuit is a fire risk
- Marking: every cable labeled with rating and connector type (labeling prevents the mix-up that starts backline fires)
