Punch outs
 
If I have a receptical or box that has one punch-out used and I need to use a punch-out in a different location, do I need to through the recepticalor box away and use a new one or can I cover the hole with something (not sure what)?

There are filler caps you can get at most hardware/home improvement stores. They are usually available in 1/2" and 3/4" sizes. Larger sizes tend to be harder to find. Probably going to be about a dollar or 2 for a small pack of about 3-5 knockout caps. The two varieties I have seen one is a snap in cap, the other is a screw assembly that basically looks like a large washer on the outside with a small metal plate on the backside to screw into. I tend to like the screw type better than the snap in.

metal boxes will have KO seals to cover unused openings.

And you can install them from the inside of the box or from the outside. Outside is preferable. :thumbsup:

I found them. Thanks. I was getting ready to ask this. It seems like the edges on these caps are relatively sharp. I was worrying if they could fray wires?

Use plastic KO fillers if your worried, or do what I do and bend the tabs over.

I usually try to either use the existing hole, or if I can just replace the box; especially if its more than one KO hole to fill. Boxes are pretty cheap, and it just looks better not to use the filler caps, but there is a time when they are certainly necessary.
