Wiring A Fluorescent Lamp Circuit

 

Background

Wiring Fluorescent Light Fittings are very common among Electrical Installation Work. They come in various power ratings and lengths. We are discussing here of a 36W ,4 feet length Fluorescent Light circuit for 50Hz, 230V AC Power Supply. Installation work described here is according to British Standards [ IEE Regulations and Practice ].

Material Requirement

For Industrial applications, 1.5 mm2 [called as 1.5 mm squared] Cross sectioned double insulated Cu [Copper] Cables [Cu/PVC/PVC] are used for the Phase [Live ] and the Neutral cables.

For Residential applications, 1.0 mm2 Cross sectioned double insulated Cu [Copper] Cables [Cu/PVC/PVC] are commonly used for the Phase and the Neutral cables.

Earth [Ground ]cable should be 2.5mm2 single insulated Cu[Copper] Cables [Cu/PVC] for both Industrial or Residential type of applications.

 

Accessory Requirement

4 Feet 36Watt Fluorescent Lamp -01 nos.

40W Magnetic Ballast -01 nos

Starter and base -01 nos

Fluorescent Lamp Holders -02 nos

PF correction Capacitor-2.5 micro Farad -01 nos

Fixture to install above accessories

MCB 6A -01 nos [ from a Distribution Board already installed]

 

Preparation

Install the the accessories except the Lamp in to the Lighting Fixture where appropriate holes are provided to fix with nuts/bolts or Self tap screws.

 

Method of Wiring -Residential

Make sure that the Power is isolated [ shut down] to the Distribution board or any circuit you will be working with.

Connect the Phase [L] wire to the outgoing side of a 6A or a 10A [Maximum] MCB from the Distribution Board [DB]. Draw the Phase wire to the Fluorescent Light Fitting and connect to one terminal point of the Magnetic Ballast. Connect another wire to the other terminal of the ballast and connect to one of the terminals of the holder termial of the Fluorescent Lamp.Connect a wire from the terminal of the other holder termial of the Fluorescent Lamp to the Starter base terminal. Connect a wire from the second terminal of the Starter base to the second holder termial of the Fluorescent Lamp

Connect the Neutral [N] wire to the Neutral Link provided in the DB and draw the wire to the receptacle and connect to the unconnected terminal of the Fluorescent Lamp's second holder as shown in the diagram.

Connect the Earth [E] wire to the Earth link provided in the Distribution Board. Draw Earth wire to the Fluorescent Light Fitting and connect to the Earth point of the Magnetic Ballast.

It is good practice to number the Phase and the Neutral wires at the DB for easy identification as one circuit.
