These all lamps are connected in Parallel. Each lamp or Bulb is connected between Line L (also known as phase) and Neutral N.
In this circuit,adding or removing one lamp has no effect on the others lamps because the Voltage in parallel circuit is same but the current is different. Any number of lamps can be added in this kind of circuit, simply by extending the L and N conductors to other lamps.

Advantages of this circuit:

  • In case of break in the cable or removal of any lamp will not break the all circuits, in other words, other lights/lamps will still work and glow.
  • As more lamps are added, they will all be reduced in brightness. Because voltages is shared or divided in a series circuit.


  •  More size of cable wire is used in parallel lighting circuit wiring.

  1. Thanks for your appreciation,

  2. Nice post. This the normal and efficient electrical wiring in the houses. The most commonly used wire is copper coated with the PVC. Copper is used because of the best electricity conducting behavior. Nearly all large cities and smaller ones now follow the recommendations of the National Electrical Code. Electrical wiring is generally done by the experienced and certified electrical contractors

  3. I have two garage door openers running off the same supply voltage. i currently have an external outside light the is wired to one of the garage door opener’s relay. When that garage door opener (GDO) ii’s activated, the external light comes on and stays on until the GDO lights shut off. Very convenient. I now want to use the same external light but with the other GDO. I am worried that if I wire the second GDO’ relay to the same light and both GDOs are activated at the same time, there will be two (2) 120 VAC feeding the light at the same time.
    Is this a problem?
