light switches in a mobile home


needing to replace a light switch in a 1997 mobile home. Went to lowes and said that I could just use a regular light switch but when I took out the box it had 3 different sets of wires going to the old switch 3 black, 3 white and 3 copper. What do I do with all these wires?

It should able use the standard light switch so therefore all the bare conductors are wirenutted or crimped then all the whites are together and wirenutted and last thing is you have to know which one is your power source and one for the luminaire once you sort it out it pretty easy to make a pigtail and hook it up.

The best thing is take a picture and you should have a junction box in there as well due that kinda pretty new MH you have there so it should not have that oddball switch at all.

Merci.

It sounds like one of those self-contained switches that do not require an outlet box. Personally, I detest those devices ...

The OP will have to get a pop-in type box, and install that in the hole in the wall left behind by the old wall switch.

Strip the sheathing from the cables, and install them into the box, and then make it up like any other "normal" switch. Identifying the switch leg will be an important part of successfully completing this task.

Remove the existing switch, pull the cables into and install that blue old work box. Twist the whites together and install a wire nut (they are not connected to the switch). Pig tail the bare grounds together and connect to the ground on that new switch (you need a short piece of bare wire to make up the pigtail). Connect the 2 blacks to the new switch.

So, I won't be using the white wires at all? I'm confused because the white wires seem to be used in the old switch. I'm so afraid of electricity but I'm more afraid of a professional electrician bill just to change a light switch.
Thanks so much for all your help!

The white wires wonít attach to the switch. They only appeared to on your original switch, but they were actually only connected to each other inside of it. Strip back and remove a couple more inches of the sheathing of both cables before you put them in the new box and put the box into the wall. Youíll need more free conductor to work with. Be aware the sheathing has to enter the box though, so donít take too much off. Also cut both white wires back to get rid of the knick in the insulation.

Neutral conductors are never switched. Strip them back and nut them together.

Not true. Neutral are rarely switched.

You can use a switch to disconnect a neutral if all of the ungrounded conductors of that circuit are simultaneously disconnected, or be arranged so that the neutral can’t be disconnected until all the ungrounded conductors are disconnected first.

I know what you mean, it’s just inaccurate to say never.

Hmmmm. Never heard that one.

Would it be accurate to say that's rare in basic residential applications?

It’s an exception to 404.2(B). Yes it’s rarely, if ever, used in residential. Don’t think I’ve ever seen it done in a house, usually no need to.

So, I followed the directions from you nice folks and my light is fixed! Thank you so much for your instructions. It may not seem like much to some but for someone on a fixed income, being able to fix my own light switch instead of paying a "professional" is like winning the lottery. OK not like winning the lottery but maybe like finding $10 bucks in the pocket of an old coat.
Anyway, thank you again for your help, I truly appreciate it.

Anne
