## Description

Features: The weatherproof junction box cable connector is safe for home, garden or outdoor lighting. Using it to repair and extend power cables. It is safe enough to repair and extend electric wires . Technical specifications: Voltages of 250V Rated current 12A--16A Protection class: IP67 Waterproof Frost resistant T branch wire sleeve,the connection of 2 or 3-pin cables, Easy connection, DIY tools Very tidy design, waterproof and have a good seal on them The connectors include " live wire" "neutral wire" "earth wire" Suitable for fast connection to the outdoor lighting, and external wiring Package Includes: 1 x T junction box

Review: No problems at all - Not sure about the comments here about terminal labelling as mine had a clear 'G', 'L' & 'N' marked on each terminal. They come with a free small head Phillips driver for the terminals, this is adequate if you apply a fair amount of pressure when tightening so that the driver doesn't slip and chew the head of the terminal screw. I use my own screw driver. Anyone who wants a smaller, quality IP connection will accept that you have to use smaller terminal screws and these are some of the best that I've come across. I can't fault the quality. Good solid cable grip when using flex. I opened the connector after hard rainfall and there was no water ingress at all. They look great and are straight forward. What more do you need?
Review: Looks the part, robust but not brilliantly engineered - Very fiddly getting the waterproof insert set in the caps. The recesses into which the wires are screwed are not deep enough. Consequently, when you tighten down the end caps, the torsion pulls the wires out of the recesses.

### ⭐⭐ Looks the part, robust but not brilliantly engineered
*by M***D on 20 February 2018*

Very fiddly getting the waterproof insert set in the caps. The recesses into which the wires are screwed are not deep enough. Consequently, when you tighten down the end caps, the torsion pulls the wires out of the recesses.

### ⭐⭐⭐ Clever design but flawed
*by T***E on 24 February 2017*

Just about ok for light wiring but has two flaws. There is inadequate space for the wiring. And the threads on the plastic sleeves are too short, and except with light wiring they will not grip.
