KING INNOVATION 62310 3PK BLU Wire Connector, 3 pk, Blue

I’ve been an outdoor lighting owner and installer for 7 years and these are always my go to waterproof wire nuts. Fits many sized wires and easy to use

These wire nuts work very well for outdoor wiring. They have a more than adequate connection and I believe that I should get years of good waterproof continuity in my wiring. BUT, have paper towels or a rag handy because your going to get greasy from all the silicone that comes out when you insert the wiring into the nut. At least you know it’s a water proof connection. I would recommend these to anyone.

I’ve been an electrician for 30 years. I don’t do a lot of outdoor/landscape lighting, but I have a good customer that wanted me to rewire and replace 30 post mount lights. I normally use dielectric grease in a standard wire nut, but I needed to make 90 connections, so I figured these would save some time. I was wrong! As soon as they started to grab, the coils came loose. I’m assuming I might have gotten a bad or defective batch because the reviews were pretty good. I even tried pre-twisting the conductors, but made no difference. I really wish these were constructed better, probably would have saved me a couple hours. Luckily I'm still in the return window, so off they go!

Works great for hardscape lighting.

I like these. I used them to install new tail lights on my boat trailer. They are packed with silicone caulk or such. When you poke the wires in it evidently breaks a seal. When you screw it on the wires a tiny amount of sealant my leak out, but makes no mess; just shows it's sealed good. I have sealed wire nuts before using a tube of silicone and mashing it in the nut, but I never know if I get all the air out, and it makes a sticky mess. These are not cheap, but so convenient!

I have used a two different sizes of these King products. The work great and make for a waterproof connection with no hassle. Out of something like 30 connections I only had one connector fail as I was trying to screw it on. Unlike others, I believe the size is correctly described for the appropriate gauge wire and recommend simply paying attention when ordering to the size wire King describes for the specific connector. I used the Blue pack for tying two 12 gauge wires to a 16 and I used the Red for tying one 16 gauge to one 12 gauge. The Red could handle more, but it worked great.

I live 400 feet from the Pacific ocean and the electrical connections for my solar panels continually corroded and broke. Numerous fixes by 'experts' proved to be expensive and short lived. I finally came across these and they work but for how long is yet to be determined. When attached the copper wires are embedded in waterproof silicon. These should be a lasting solution.

Much more cost effective than purchasing the clamp on connectors and probably will have a better connection life. I have used these with 3 #12 wires or 1 #10 with 2 #12 wires and they fit easily. Could easily do 3 #10 wires. I just bought a second pack as I am doing lots of landscaping right now.

The best exterior wire nuts money can buy.... I know because I have been in the business for 42 yearsCanadian Master Electrician.

The gel-filled cap needed to be taped securely to the wires otherwise it will get loose, the wire connection exposed and left unprotected from the elements.
