Tapping into circuit in attic?
What is the proper way to tap into an existing circuit in the attic so I can get power to a new ceiling fan? Can someone post a diagram or a link. I also want to add via attic access 2 ceiling lights to a bedroom so I want to tap into a circuit over the bedroom.

Use a junction box. I used my bedroom lighting circuit, when I hooked up my attic vent fan. Keep in mind, that if you are nearing the limits on the 15 amp circuit.

i understand to use a junction box, but what if the wire i'm tapping into does not have enough slack to comfortably do it? what is the best way to add the junction box then?

Certain circuits should not be tapped into as they a dedicated to specific usages.

Without enough slack you need to add 2 junction boxes.

add two junction boxes and wire between them

Be sure that all power is off in that cable before cutting it.

And be sure of what cable you are cutting into. If the cable happens to be a switch loop, then you can't get power from it. There will be no neutral. Even though there is a white wire it will not be neutral.
