fitting a fluorescent tube

[steve07951]

Mount the fitting so that it is securely fastened to the ceiling and joists above.

Locate it in such a way that the access in the back of the fitting is as near to the cable feeding from the ceiling as possible.

Feed the supply cable in through the back of the fitting.

Protect all exposed earth conductors with green/yellow sleeving.

With a single cable, junction box type circuit, the cable is easily connected to the fitting – red to the live terminal, black to the neutral terminal and green/yellow to the earth terminal.

If you have a loop type lighting circuit, the multitude of conductors cannot be accommodated in the fitting. Take the cables back up into the ceiling area and wire them into a securely mounted four terminal junction box. Ensure that the connections made exactly replicate those originally made in the rose. See ceiling rose cable identification.

Allocate one terminal for live in, live out, and live to the switch.

Allocate one terminal for live from the switch.

Allocate one terminal for neutrals.

Allocate one terminal for earths.
Run a length cable from this junction box. Connect the conductors to their corresponding terminals, being sure that the live picks up from the terminal housing the live from the switch.

At the light fitting, make the connections for the conductors as before – red to live, black to neutral and green/yellow to the earth terminal on the backplate. Replace all covers.

Once you are sure that all work has been completed correctly, replace the fuse for the circuit, switch the power back on, and test.
