Customer Questions & Answers

Can I use this on 18-3 cord?

Asked by: WyattEarp
WyattEarp the 18 gauge wire is a little small as the connector is rated for 14 to 8 AWG conductors and I'm not sure if the heat shrink with seal around the smaller conductors. Good luck on the project Ron at

Can this splice be used on underground lamp post wire (14-2 UF, SOLID)? I've read that most of these splice kits are only good for stranded wire. Plus I'm guessing that 2 of these kits would be needed (with a small jumper) which would make this a very expensive splice....... thoughts?? Any help would be appreciated. Thanks.
Asked by: Mike
Mike you can use them on solid wires. If you need a stretcher kit with a little wire that will splice the wires back together it is our 46-410 unfortunately Home Depot does not stock it but any store can special order it for you. Good luck Ron at

So this will work with 6-3 wire?

So this will work with 6-3 wire?
Asked by: waltjmk
Hello waltjmk, I’m Chris from the Home Depot’s how-to Community. Thank you for your question. This kit is for smaller wire than the #6 you want to splice. Please use this alternative instead, which is the model #46-401. You can find it here: I hope this helps, Chris. .

Asked by: RRRWOODY
Hello RRRWOODY, The best way to shrink heat tube is with a heat gun. If you don't have access to a heat gun a hair dryer on high often works just as well. Heat shrink tube works by constricting and shrinking when heat is applied. I hope this helps. Cheers, Chris

Rated 3 out of 5 by from Good connection hardware for cable I liked the connection hardware included with this product. The set screws appear to be stainless steel in a brass sleeve and I was able to really torque the screws down onto the wires, holding everything together in a solid fashion. The reason for the 3 stars rather than a higher rating is related to the shrink tube portion of the product. It did not really shrink down very well and I would not trust it to be 100% water proof. I used a soft flame from my propane torch. The shrink tube seemed to need more heat, but more heat started to burn the Romex cable, so I could not really get enough heat onto the tube to shrink it completely. Not sure how well this will work for underground applications. I had to put mine in a large pvc conduit, which I did not want to have to do.
