They are almost as easy to use for high current connections as banana plugs, and you don’t accidentally disconnect them.įor stranded wires, I’ve made a few with lengths varying between 5cm and 30cm, stripped them, and tinned the ends. I do not do much mains wiring, but I mostly use these on my electronics workbench for temporary connections for all kinds of higher current connections such as power supplies, motor controllers with MOSfets etc. I quite like the model tested by Big Clive in: Overall, the price difference is just too small to bother with, but there are some exceptions. I had Blue wago 221 knockoffs (not tested by Scott) and the holes in these are too small, which basically means you can put the bare copper through the hole, but not the isolation. ![]() Some of them are quite all right, while others are just garbage to work with. I’ve also bought several models by mail from that country far away, and my feelings are mixed. Posted in home hacks Tagged clamp lever terminal, electrical safety, house wiring Post navigation One of these being the connectors by the German brand ViD, which would seem to be a slightly cheaper alternative to the Wago connectors, with similar guarantees of safety.Īt the end of the day it is the certification that matters, after all, since long-term reliability is of primary concern with house wiring, not whether a few Euros were saved on material costs. While running the connectors through their paces with high-current, fire and mechanical strength tests, the conclusion was that all are good enough for hobbyists use and some brief connections while testing, but that only the ones with independent certification marks (like VDE) filled him with enough confidence to consider using in house wiring. The resulting selection of seven connectors come in a wide variety of shapes, colors and configurations, though all are supposedly rated for mains (250 VAC) voltage and safe enough to put into a permanent installation. This was the thought behind a recent video by (also embedded after the break) when he hopped onto everyone’s favorite e-commerce website and searched for ‘clamp lever terminal’. When it comes to no-fuss wire connectors, Wago clamp connectors are an attractive target to save some money on due to their perceived high cost. ![]() At the intersection of saving a few bucks and expensive home insurance claims due to a house fire, we find clones of certified and tested electrical connectors, even when many would argue that so-called wire nuts are fire hazards no matter how many certification labels are on them.
