4 units across 1 rack: 1,250W / 1,389 VA. 240V single phase: 7.2A total draw with headroom. Inrush est. 22A — stagger startup to avoid tripping breakers. Generator: 5 kVA minimum. Cooling: 1.3 kW — low density — standard room cooling sufficient. Venue/touring: allow extra headroom for unknown power quality, long cable runs and shared feeds.
