multiple light switch wiring
The use of a 4 gang 4 bulb wiring diagram shows how it is possible to switch on / switch off four light bulbs with the use of four separate scitches controlled independently. The switches should be connected in series with each being connected to one bulb, and should be on the same phase and neutral. This is a more independent control of every light and could be used in a switchboard of rooms, hallways and offices.
Wiring Formula Summary:
- Total Power: Ptotal = P₁ + P₂ + P₃ + P₄
- Current per Bulb: I = P / V
- Voltage: V = 220V AC (Standard)
- Connection: Each switch in series with its bulb
4 gang switch wiring
One 4 gang switch 4 bulb wiring will enable an individual bulb to be turned on/off by a switch.
