Single Junction Box Radial System

  • This is an example of the single junction box radial system.
  • One cable brings power in, one cable takes power out, one cable goes to the switch and one cable goes to the light.
  • Wiring can be complex and time consuming.
  • All wires are cut to a variety of different lengths.
  • Any maintenance of the junction box or adding additional light switches and light connections can be very complicated.
  • Cables are not strain relived.

Loop-in Ceiling Rose System

  • This is an example of the loop-in ceiling rose system.
  • One cable brings power in, one cable takes power out and one cable goes to the switch. This method eliminates one cable connection as all cables are wired directly into the light.
  • Wiring can be complex and time consuming with 3 cables to strip, bend and wire with limited space available.
  • All wiring has to be done above head height which isn’t good ergonomics for the electrician leading to neck and arm strains.
  • End users don’t like ceiling roses as they have to be removed to accommodate modern light fittings, leading to complex wiring and extra expense.
  • Most wiring is completed on the second fix.
