Dual Supply Lighting Distribution Box

The Dual Supply Lighting Distribution Box makes it possible to independently control two groups of luminaires, each separately supplied by its own protective device at the distribution board. The desired supply split point is factory configured to order. In common with all units in the range the type of control can be simple on/off or dimmable. If using third party control products (i.e. switches/sensors) they will require hard wiring to the input terminals provided, but for ease of installation we strongly recommend selecting the appropriate control from our extensive range of plug-in control devices. Reserve one outlet on each side of the supply split for this method. Use for installations requiring an essential and a non-essential supply such as hospitals, or for load shedding applications. Note: Supplies must be on the same phase.

Key Features

  • Outlets rated 16A 230V. Total system rating 16A.
  • Large capacity input terminals can accept 3 x 2.5mm², 2 x 4mm² or 1 x 6 mm² conductors.
  • 7-pole – ideal for on/off or dimming control
  • End outlet can be used as a spare, or to plug-in additional units.
  • All units come with unique snap on/off single point fixing brackets.

Expanding a Dual Supply Distribution Box

If you want to add extra luminaires at any stage you just need to plug an Expansion Box into your Dual Supply Box to provide extra outlets. Extra outlets will be added to Supply Group B.

If you want to control an extra group of luminaires separately, share just power from your Dual Supply Box using a Supply Tap-off Box.

You can plug them in direct unit-to-unit, or via a lead.

Wiring Diagrams

Using flex7 plug-in control devices c/w integral emergency luminaire test means 2 x permanent live, 2 x neutral and 2 x earth are required.

Note. Although the 2 supplies have different protective devices, they must be the same phase.

Using flex7 plug-in control devices without integral emergency luminaire test means 2 x permanent live, 2 x emergency live, 2 x neutral and 2 x earth are required.

Note. Although the 2 supplies have different protective devices, they must be the same phase.

Using more traditional hard-wired control and emergency luminaire test means 2 x permanent live, 2 x emergency live, 2 x neutral and 2 x earth 2 x switch lives are required.

Note. Although the 2 supplies have different protective devices, they must be the same phase.
