Distro boxes and rack PDUs covering everything from a stage corner to a full site feed: PCE and Elumen8 MERZ and ISCHL distribution boxes taking 63A or 125A supplies down to 32A and 16A ways with RCD and MCB protection, a 400A Powerlock distribution unit, Socapex breakout boxes, and Penn Elcom rack-mount PDUs including powerCON TRUE1 and Schuko versions with power monitoring.

Work backwards from the supply you will actually be given. A 63A single phase feed and a 415V three phase one need different incomers, and the output mix, meaning how many 32A and 16A ways, should match the rigs you feed rather than simply looking generous on paper. Check what protection is on board, since RCD and MCB protection at the distro saves a long walk to the venue’s own board when a circuit trips. On three phase units, plan loads across the phases rather than piling everything onto the first one. Rack PDUs answer a different question, clean and tidy power inside a rack, with monitored versions useful for spotting a failing amplifier before it fails completely.

Feeder cables and the 32A and 63A connectors these boxes rely on are in the neighbouring categories.
