Preciva Compact Wire Connectors, 33pcs Push Fit Electrical Blocks

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.

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.

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!

Easier and way safer to connect old wires together without soldering

good product easy to use

Being a sparky,always get my electrical parts from Amazon.Great value for money.

Look and feel a quality product. Got these more for use in my caravan on 12V DC system but they are rated for 230V AC so may end up using in the house occasionally. The clips have a good snap action and feels secure when wired.

Ideal for workshop.

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 !
