Preciva 100pcs Compact Splicing Connector, Lever Nut Wire Connectors

The connectors arrived packed in a reasonably solid storage box, with a good catch that should last a fair while. UKCA and CE marks on the box and we're off to a very good start. Visually they look very similar to the Wago 222 series, even down to the moulded length guide for stripping the insulation of the wire to be used with them. Of course, looks are not the main feature, they need to perform well too. The levers have a very positive snap, but also aren't too tough to open. Inserting a wire is easy, the contacts are formed with a slope to guide the wire in. Once secured in place the wire is held firmly. Pull out resistance is on par with other connectors there. They grip thick cables and thin cables well, solid core and stranded. Electrically, I connected a 50A 12V power supply through one of these connectors, and a Wago 221 series and lit several automotive bulbs and an electronic load, until the draw from the power supply was 32.5A. The Preciva connector did not get appreciably warmer than the Wago connector, both remaining around room temperature. This shows their grip of the cable and resistance of the joint are on par. In summary, they seem fine. A solid choice at a reasonable price point. The box will be handy in the garage for quickly joining cables and putting circuits in.

Product really simple to use and can accept up to 32amp solid core twin and earth (4mm) cable and also up to 25amp flexible multistrand (2.5mm) cables. The three connections enable ring circuits with a spur to be easily created. The connections once made are very secure once the clips are closed. The clips have quite a powerful clamping action and can pinch if they spring back if your grip slips or they are not in the fully locked position so care is needed especially if you have weak hands (the instructions does warn about this) a decent pair of gloves can mitigate against this. Add an efficient wire stripper and these connectors make wiring a doddle I found them especially useful for lighting circuts. 5 stars

They're not name-brand Wagos, but they certainly do the job for DIY projects. Just don't use them for more than that as I'm not confident in the lever lock durability - though they're easy to operate and connect well when new, a few had broken levers right out the box. A good fit for DIY projects but don't rely on them exclusively!

Really love these, used to install a few ceiling lights and they're a lifesaver for someone with fat fingers. The quality is very good and the levers grip very well. Will definitely be buying these again.

Very good material

Really like these. Got them for the wiring on my OO gauge layout. Easy to connect wires. I actually have about 10 common wires connected through one of the 4 point connecter. They hold together well, either separate wires, or twist them together. Some I used to join wires for testing before soldering, work well.

I've seen these around for some time and decided to give them a go . Why did I not get them before. Easy to use , neat , fast , no fiddling with screws and the like. This is a handy set to start with and comes with an ideal storage box.

Great selection of connectors and good value for money. Just be carefully as the orange clips snap down quite viciously and will catch your finger and hurt!

Grand job and save alot of time, look and feel to be well made and hold the wire tight.

​Mon avis après utilisation : ​J'ai pris ce coffret de 33 connecteurs électriques à levier (Preciva) et j'en suis vraiment très satisfait. C'est idéal pour faire des branchements propres, solides et surtout en toute sécurité, que ce soit pour de l'éclairage ou des prises. ​Ce que j'ai particulièrement apprécié : ​Connexion sûre et solide : Le système de levier orange s'enclenche parfaitement. Une fois le câble inséré et le levier rabattu, le fil ne bouge plus d'un millimètre. ​Polyvalent : La boîte contient un panachage très utile (10 connecteurs 2 entrées, 18 de 3 entrées et 5 de 5 entrées). Ça permet de s'adapter à toutes les configurations de câblage. ​Compatible tous fils : Fonctionne très bien aussi bien avec du fil rigide qu'avec du fil souple. ​Boîte de rangement pratique : La boîte en plastique rigide permet de garder tout bien trié dans la caisse à outils sans en perdre. ​En résumé : Un excellent coffret, robuste, qui fait gagner un temps fou par rapport aux dominos classiques. Le raccordement est fiable et sécurisé. Je recommande sans hésiter !
