I am in Australia and I wish to wire in an exhaust fan to my fluro light operated by the one switch.
The switch has a red wire and a white wire leading to the fluro light. The fluro has twin and earth (red, black and green) leading from a previous light in another room and another exiting to the next light in the house. The fan has two wires, a brown and a blue. I attempted to parallel the wiring by connecting the blue to red and brown to white. Once the fuse was turned on, the fan operated automatically and the light flickered without the switch being turned on. I reversed the wiring (brown to red and blue to white) with the same result. Logic failed me. Given that it is two wires on the fan (pos and neg I assume) I figure I am better parelleling to one of the twin and earths, but which one? Electricians charge a minimum of $240 per hour here, with a minimum of 1 hour charge, regardless of it being a 2 minute job. All connections are 240V. Wire joins will be completed using BP connectors.
