Domestic house wiring and remote control

Not sure what your question is asking as the cables are already connected. From your description it sounds like you have a control unit and an isolator, if that's correct both serve their purpose. Kevin.

The question you're actually asking is unclear, however if the lighting circuit has been wired using the "loop in" method, then what you're describing is likely to be as follows. Three separate white cables at the ceiling rose, each with an inner red, black and bare copper conductor inside. The three red conductors are permanently live, so this is ideally where you would connect the wire that controls the fan via the remote to, as this will allow the fan to be used via the remote irrespective of whether the light switch is in the on or off position. The three bare copper circuit protective conductors (earths) should be covered with a green and yellow oversleeving and must be securely connected to the metal mounting bracket for the fan and the earthing flylead to the fan motor. If the earthing is not corrected properly, then there is a risk that the metalwork of the fan could become live if a fault were to occur. For the three blacks, it's not as simple as joining them altogether. Two will be neutral conductors and the third will be the switchline return. As there is no easy way of telling them apart, the switchline will have to be tested to identify it (easiest way is to use a continuity tester or buzzer). Once identified the single black will be the conductor that you connect to the live side of the lamp. This will then turn the light on and off when the wall switch is operated. Hopefully this is of some help, however it maybe better for you to re-phrase your question, as reading between the lines it would seem to suggest that your looking to do away with the wall switch and just solely use the remote control unit to control both the light and the fan? Remember messing around with electricity can kill you, if your not 100% clear on what your doing. As such its safer to get a professional in. This sort of job is likely to be sorted in 15-20 mins.
