Answer 1

the red wire is the hot wire my husband just put in a dimmer switch

Answer 2

Buy a tester.

Answer 3

On a three way switch, red is the traveler. It's hot and allows you to control the light from two different switches.  The black is hot and the white neutral. Green is the ground.  The two black on the fan connect to the black wire, and the same for the white.  The red wire is usually wired from switch to switch and is not seen at the fan.  Also connect the ground wires at the fan.  If the fan is mounted in a metal box, add a ground pig tail to the box and connect all three green.

Answer 4

There is no red wire? Then that is not part of this discussion.

The black wires are hot, the white are neutral.

It sounds like you have access to wire the fan and the list separately, in case you want to be able to switch on the light without using the fan.

Answer 5

r and b are hot and w is nuetral  Bare is ground

Answer 6

This is another case of "If you have to ask....."

With a Cable Assembly type wiring system, any wire but white should be either a switch leg, or an ungrounded ("hot") conductor; BUT, you must test them all, because they are allowed to be re-indentified for switching situations, and sometimes, electricians (with a small "e") will forget to mark the conductors.

The best way to identify which are "hot" is to purchase a "stupid stick", or Non-Contact Current Tester. Turn all switches off, then close them (turn them on) one at a time (while holding the current tester near the conductors). Move the tester from one conductor to the next. When it lights up, "chirps", or does both, you know that you have found the switch leg for that switch. (Be sure you test all conductors with all switches opened or off, first. This will tell you if any conductors at the fixture are hot, and not switch controlled - leave them alone.)

If you have 3 switches, I am assuming that only 2 control the fan/light combo, and the other controls the vanity light. If all three go to the fan/light combo, all bets are off, and you better hire a qualified, licensed Electrician. (Something that you should do in the first place, but probably won't, because "it's only a small job, anyone should be able to do it.") To that, a say "Please read Article 90 of the NEC. Read Article 90, Sections 90.1 (A) & (C) two or three times, and really think about what they mean."

Answer 7

Connect the red to 1 black, the black to the other black and all the white wires go together.
