How does the power distro box work?

PowerSafe Connector Mating BoxThe Powersafe distro box is the perfect portable power distribution device for temporary power supply for events, stage, theatre, stadiums, data centres and more. It incorporates an integral shutter mechanism which controls the connection sequence on the electrical panel board. The sequence of connection is:

  • Turn key to open Earth lock – (the Earth cap will open to allow connection of the Earth connector).
  • Plug the Earth connector in and turn clockwise to its locked position – (the Neutral cap will open to allow you to plug the Neutral connector in).
  • Continue the sequence on the power distribution box with L1 and L2 and then when the L3 connector is plugged in and engaged, turn the lock key to the closed position (this will lock all the connectors mechanically in place so that they cannot be removed and it will also operate an internal micro-switch).
  • The internal micro-switch can be used as a signal path to operate electrical protection devices. A 3 pin connector on the rear of the heavy duty box is provided for easy connection, this can be used to trip the supply to the box should someone open the Lock key whilst the supply is present.
