Romex Splice Kit
 
Hello,
I purchased a ROMEX CABLE SPLICE AND TAP KIT from a local hardware store a few years ago and never used it.
My Father in Law started talking about a project he could use it on..
Adding a few lights in his attic.

Does anyone know Is this is up to code in Michigan???

Thanks,
Tom

As long as its properly listed, it should be ok. Make sure that the amp rating is right, the type of wire is compatible (ex. 14/2 14/3 etc.) Wires are properly secured. Check with local codes because they are the final word.

Personally, I would use junction boxes.

If I remember correctly they are a device that you put on existing lines and press some knives (for lack of better word) into the existing wire and then wire from there.

I have never liked these kind of connections just like I don't like the push in receptacles. They cause some minor arching and put a lot of noise in the power lines. I am a fan of clean sine waves and use the screws on my receptacles. More work but way less noise on the power lines.

I doubt they are code but anything is possible.

Hey Marv, At what harmonic do you see the noise from push-in connections?

It varies. I run X10 on my house wiring and had a lot of problems getting signals to go more than 20 feet. Sometimes the signal had to run down one let to the panel and then up the other leg. That was a real problem.

I read somewhere that the push in connectors would cause very minor arcing and would put enough noise in the line to dilute the X10 signals.

So one day I decided to give it a try and replaced all my receptacles that were push in and used the screws and all of a sudden my X10 worked all through the house. I have never had a problem since.

The oscilloscope would just show a lot of artifact with no random pattern. X10 relies on the null phase and that is where there is a lot of noise in most homes.

What really screws up my X10 setup is wall warts that go bad. Talk about artifact. It is like a sine wave having a seizure.

X10 doesn't get along will with noise in the lines and I am glad that finally there are some alternative home automation technology like Z wave, zigbee and insteon that are much more reliable.

I would not use anything like that...

I have seen these splices used in prefabbed homes. Not trailers but real houses that are built in sections in a factory. Every thing goes together like a puzzle except the roof, which is built onsite. These NM splices are used when connecting wall sections. The cable and boxes are all installed at the factory, so you need a way to connect each section electrically. Personally they scare me, but they are UL approved for NM. Now, where and how you use them would be my concern. Make certain you follow the manufacturers instructions. If you don't, you lose the UL label.

Is it like this? http://www.smarthome.com/7104/Modula...4130062/p.aspx

This is UL & CSA listed.

hogger9 10-09-2008 07:16 AM

Yes.... That is the same style but different Mfg. And states: NEC approved Articale 334-40b 2005 NEC & UL Listed

It looks ok for a few lights, wouldn't use it for an outlet. Make sure that its ##/2 wire hes using it on, and make sure its copper! no copper clad or aluminum, unless rated for. Even if it was, I wouldn't splice aluminum without copalum.
