BG 883P Nexus Moulded White 3 Gang 2 Way Push Dimmer 400w is a modern design that will blend with any décor. Suitable for use in domestic or commercial installations. 


  • Stylish modern profile finished in White

  • Covers to conceal fixing screws for a clean finish

  • Colour Coded Terminals with backed out captive screws for easy installation

  • Dimmer type is Leading Edge

  • The dimmer unit will emit a faint buzz and may become warm while in operation, this is quite normal and no cause for concern

Further Dimming Information on BG Dimmers

  • Tungsten dimmers are not suitable for dimming any transformer, low voltage, fluorescent or motor loads.

  • Mains voltage tungsten halogen lamps may be dimmed, but the maximum rating of the dimmer must be de-rated by 50% (i.e., a 40-250W dimmer must be treated as 40-125W, a 60-400W dimmer as 60-200W, etc)

  • Low Voltage Lighting 2-Way (Push ON/OFF) low voltage dimmers are only suitable for dimming wire wound laminated and some dimmable electronic transformers

  • They are not suitable for dimming torodial transformers, Fluorescent or Tungsten Lamps

  • Many electronic transformers are not dimmable and many which claim to be dimmable may not be compatible

  • Most UK dimmers, use a 'leading edge' principle, therefore, transformers which require a 'trailing edge', 'falling edge', 'phase lagging' or 'transistor' dimmer, must not be used

  • To dim any compatible transformer, a low-voltage (inductive) dimmer must always be used

  • These are not 'inductive only' dimmers

  • The dimmer VA rating refers to the total circuit load, not lamp load. Allow for transformer losses. Typically 20% (or 15% for electronic transformers)

  • Therefore, maximum load for 400VA dimmer becomes 330W (350W electronic), and 250VA becomes 210W (215W for electronic)

  • Low voltage dimmers should be connected on the 'mains side' of the transformer

  • Load resistors are not required

  • Transformers should be installed in accordance with the manufacturer's instructions. If set-up with laminated transformer either buzzes excessively or lights flicker, it may be necessary to install a snubber circuit across the transformer primary. (one per dimmer circuit)
