Metal 3 Gang Box with Romex


Hi,

I have a 3 gang metal box with two BX cables and now two Romex wires. The box is mounted in plaster so I am really trying not to take it out. I bought the 1/2 inch plastic clamps to lock the romex into the metal box but the holes are tiny. I can't find any hardware store that has anything smaller than 3/8. To follow code I want to make sure the wire is secure in the box so that it doesn't strain the conneciton. Also I am concerned that the sharp edges on the metal box could cut into the romex. Any idea how to fix this without removing the box? Thanks.

Just use NM straps for a metal box.

Sounds good but I was told that you can't use metal clamp on a Romex wire? Is my info wrong?

You were misinformed... they are designed for NM. Make sure it looks like the clamp in the picture. Funny how people actually feel confident about giving out advice when they really dont know, amazes me.

LOL... the funny thing is, the clamp I posted in the pic, can ONLY be used for NM type wire.

there is a similar type for AC/MC, it'll have a metal circle for the conductors to pass through at the top, to hold the armor in place

Can I ask why someone doesn't publish an easy to read NEC code book? We need like NEC code for dummies. I am not licensed but I like to follow code when doing my own work in my house. The NEC books are a little to much for a regular guy like me.

I agree. Something with all the bs filtered out.....well I guess lawyers will probably ensure that doesn't get published.

There is just too much information just to make it a simple DIY electrical book..

Thats like asking for a easy to do heart transplant, or easy to swap out your own car engine... its not going to happen.

The NEC is NOT designed to be a design manual or an instruction manual.

Personally, I think its fine the way its written, you just need to learn how to read it... Which is going to be hard for the typical laymen...

Heck, look at all the discussions between people that read the NEC on a frequent basis.

I agree with all of you that the NEC code is not meant for DIY people and I don't blame them for writing it almost in code. What I was suggesting is a simple code book for basic electrical work that the average person does on their own. We all know that homeowners do a lot of their own electric so why not at least help them stay safe and to code.

Trouble is there are exceptions to many rules and many times a paraphrased version would leave something out.
