I would like to know your opinion on extending existing wiring on a remodel job. I have a kitchen remodel where I have to extend/relocate some wiring for switching. I do not have the ability to install a junction box without the customer noticing it. My question, is do you think it would b :confused: e possible to use an underground splice kit by 3m to connect, conseal and insulate the splice and leave behind the sheetrock. The underground splice kit is the one that you use the heat shrink outer tubing filled with sealing resin.
 
Re: Extending existing wiring

Possible, yes. Code compliant, NO. But I think there is a listed device that will permit you to do this. I don't remember the product name, but I'm sure someone will.

Re: Extending existing wiring

Would he not accept a cut-in box with a blank cover? I believe Bob (iwire) posted pics of a product on another thread listed for this but I cant remember the name.
 
Re: Extending existing wiring

These are the products, made by AMP.

Go here for more info.

However, they make no mention of compliance with article 334.40 (B) Nonetheless, I am aware of contractors in my area using them for concealed splices. They were very popular sellers at the supply store at which I used to work.

Re: Extending existing wiring

Cause we must back our work for 1 year.Cover it with drywall then wall papper and see if you can afford the repair if it fails.If i was going to burry a joint it would be a pretwisted joint with wire nuts and tape in a plastic box.No not legal but just as safe as there system and i would know i made a great connection that will last for life.
 
Re: Extending existing wiring

These connections were developed for the modular house manufactures. They actually work quite well. I have never worked on one of these homes but I toured one and they bring the house in sections on semi trailers and plug the electic together where the walls match. The plumbing has the same sort of connections but for plumbing. If you ever get a chance to see one of these homes they really are an engineering marvel.
 
Re: Extending existing wiring

Not saying they won't work but if one fails how do we repair it.Isn't this the reason that junction boxes mus be accesible? It's not because if covered with drywall they would be a fire risk or safety risk.
 
Re: Extending existing wiring

So these things are only legal to use in mobile/manufactured/RV applications? Are we trying to kill poor people, or am I nuts? :p
 
Re: Extending existing wiring

george, Was wondering if you ever installed or seen one of these before.And from your post in this thread,seems that you haven't..Just looking for some input from a residental electrician.

Re: Extending existing wiring

My very first electrician job was in a mobile/modular home plant.

I installed thousands of the AMP connectors.

I do not belive they are listed for use in single family dwellings if I remember correctly.
And I do not believe they comply with 334.40(B)

I believe they are intended to comply with 550.15(K)
But, I could be mistaken.

They have their share of problems with these.
If I recall correctly, the most frequent issues were the wires not being pressed in all of the way, or , the pressure connector would just not hold the wire tightly.

I used to have some of these lying around, but I have since tossed them.

Personally, I wouldn't conceal one.
 
Re: Extending existing wiring

This thread is the first I'd heard of them. I'm with Jim on this one, IMO.

They mention on the link above that they are "545, 550, 551" compliant. I'd think if they were compliant with 334.40(B) they'd brag about it. :)
