Loop-in lighting wiring is the modern cabling arrangements used in most installation. Generally it uses less materials and is quicker to install than radial (junction box) wiring - it can however, be a bit more complicated to work out the actual wires at a ceiling rose. The NEC requires at least one ceiling-mounted light fixture in a bathroom. Most bathrooms, however, add at least one other light fixture, often a wall-mounted vanity light above the mirror or a pair of wall sconces on the sides of the mirror. My bathroom has a wall switch with three rocker switches.
One switch operates a light over tub, but also operates a light in the toilet room. The wiring diagram below shows the wiring setup you need to connect your new timed fan to your existing light circuit ceiling rose so that when the ligh is turned on, so is the fan.
