Three Phase Power Distribution Board

One three-phase feed, split safely into many protected outlets

A three-phase (400V) power distribution board, or distro box, that takes one large 3-phase supply and splits it into multiple protected single-phase and three-phase outlets for lighting rigs, stages, big PA and event or site loads.

It is three-phase equipment for qualified electricians.

This is a three-phase power distribution board, often called a distro box, built to take a single large three-phase supply and share it out safely across many circuits.

The input comes from a genuine 3-phase source, either a 3-phase generator or a 3-phase mains feed at 400V.

Inside the board, that heavy supply is broken out to a set of outlets, each one fed through its own MCB or breaker.

That means a lighting rig on one circuit, a PA system on another and general power on a third all draw from the same feed without anyone wiring directly onto the raw supply.

The board typically provides both single-phase outlets for standard event gear and three-phase outlets for the heavy loads, so a mixed rig can run from one central point.

Because every outlet is protected, an overload or fault on one circuit trips only that circuit and not the whole show.

This is high-current, 400V equipment, so it is for qualified electricians and trained power crew only.

It needs a matching three-phase supply to work, it must be kept dry, and the input feed and output distribution must be set up, tested and commissioned by a competent person.
