Power Distribution Systems

Here is how this works in practice. Mexican production power runs 127V/60Hz residential and 220V/60Hz industrial — distinct from European 230V/50Hz and matching the US grid frequency and Type A/B plug standard, so LA-shipped HMI ballasts, LED drivers, and distro stock need no frequency conversion. We set up Comisión Federal de Electricidad (CFE) tie-in permits for productions needing direct grid connection at Estudios Churubusco, Lemon Studios, Argos Comunicación, Estudios Tepeyac, Televisa San Ángel, or location residential / industrial mains.

On the ground, Standard distribution stock includes Lex Products 400-amp 5-wire 3-phase Bates feeder, ARRI Bus Bar 60-amp distros, and Mole-Richardson Mexico's heritage Junior 30-amp ribbon tie-in inventory at Cine Equipos and 3 Equipos rental houses. For off-grid Sonora and Chihuahua desert, Yucatán Maya jungle, Durango Western terrain, and remote CDMX-area location exteriors, Aggreko The country, Cummins, and Caterpillar provide super-silent 60-100kVA tow-plant gennies plus 250-500kVA industrial units for high-load HMI-heavy lighting packages. Solar / battery hybrid packages (Aggreko Y-Cube + Mobile Energy Storage Unit) increasingly handle dialogue-sensitive exterior coverage where genny noise would impact production sound.

Here is the short of it. Heritage-location power adds compliance constraints standard distribution practice does not address. INAH (Instituto Nacional de Antropología e Historia) compliance at Teotihuacán, Chichén Itzá, Palenque, Monte Albán, and protected CDMX centro histórico cathedral interiors prohibits drilled cable anchors and live-stage tie-ins to heritage electrical, needing freestanding distro positioned outside the protected perimeter with sandbag-anchored cable ramps and rubber-footed combo stands. Aztec / Maya pre-Hispanic ruin shoots use low-impact LED packages (ARRI SkyPanel S60, DMG Maxi, Quasar Q-LED) drawing 80-120 amps versus 800-1200 amps for equivalent HMI tungsten setups, dramatically reducing genny footprint.

On the ground, Major productions filmed Mexico. The list covers Spectre Day of the Dead Zócalo, Sicario Sonora desert, Narcos: The country multi-state, Apocalypto Yucatán Maya jungle, Roma CDMX neighborhood blocks, Titanic / Master and Commander / Pearl Harbor at Fox Baja Studios deep-ocean tank (Rosarito Baja California). All needed CFE tie-in permits plus Aggreko The country fleet-genny pre-positioning. Cross-border productions from LA bring their own preferred Movie Lights distro stock via Tijuana 12-minute commercial border crossing under ATA carnet through SAT/Aduanas. PAT testing and RCD protection follow Mexican NOM-001-SEDE electrical safety rules.
