- This video shows you how to install a timer switch.
In this case it's being used for a bathroom fan but really this timer switch can be used for any light in your house as well.
Maybe you always leave the light on in the backyard when you BBQ? Not anymore, set it for an hour and forget about it.
Stay Green! Having a timer switch is a nice way to stay green as well, with an automatic shut off you'll save electricity over time.

Glad you think so!
@@theelectricalguide question! In a wire diagram, would a light need constant power going to it even if it’s controlled by a switch? And nothing afterwards?
@@SilentKat No, the light would get fed from the switch, if it had constant power you wouldn't be able to turn the light off. Power from breaker to switch then the other side of the switch to light.
Thank you I learned some extra general tips as well.
Thank you for the positive feedback :)
I connected my timer but when I finished, my light was very dim. The only difference was that the light switch was a 3 wire where the exhaust fan’s switch was 4 wire. Not sure why but i think it has something to do with a 3 wire going to a 4 wire and/or the switches were jumped and when I added the neutral to the timer, it is draining electricity causing the dim light. Im not sure, I just don’t know what is causing the dimming of the light?
Tough call, so the timer is for the light or the fan? Sometimes you need a fan rated timer. When you say the "light switch was a 3 wire" does that mean it had 3 screw terminals? Or does that mean it had 3 wires attached to it? What colour were the wires? When you say "4 wire" what are you referring to? The wires attached to the timer? Nothing should be draining electricity. I'm sorry I'll need a lot more information to be able to help you here.
@@theelectricalguide thank you for your rapid response and your help. So the switch I’m replacing is a standard on/off switch that I am replacing with a fan rated timer switch to run my bathroom exhaust fan. At this point there are 2 on/off switches presently installed side by side and both have only 3 points of connection in the rear which 2 black wires and bare wire. I am assuming hot and load are black and bare wire is ground. There are neutral wires bundled up and capped tucked away not being used at all. I figured the light switches are not designed to accept a 4th wire/neutral. To install my bathroom fan timer, the instructions say “neutral required” which is fine as the neutral is there. So I removed the “old” switch and connected the new fan timer switch plus neutral and I turned breaker back on. Since I didn’t mess with the light switch, I decided to turn that on first, me being overly cautious, and the light was dim. After trying another neutral of the 4 bundled up, I got the same result, which I expected but I figured I would try since it was accessible. I undid everything and it’s all back to the way it was and the light is back to normal. This is a brand new build and I suspect that every light switch is connected the same way (no neutral connection).
@@sxirs Hrm, my best guess is that when you add the neutral to the bundle it's not making a great connection with the other homerun neutral. Usually if lights are dim mysteriously it's a neutral related problem, usually a poor connection. Sorry I can't help you much beyond that without seeing anything myself :)
