I'm wanting to install a dimmer switch in my bathroom. Hi guys At the moment I have one gang switch which turns on the lights and extractor fan simultaniously. If I fit a dimmer, will I be able to turn down the lights without it effecting the fan????? Second question, I've noticed on the new dimmer fitting it has no earth connector. It's made from plastic. So what do I do with the earth wire? Does this get connected to a point in the box? Cheers!!
