![]() Your home probably has dozens of them hidden behind the walls. Wire nuts (Figure 2) come in many colors and sizes. Unfortunately, I fear that the topic of in-line connectors is far too large for me to cover here, and so I have somewhat imperiously deemed it off-topic. Sometimes, you want to connect several different circuits, and in such a case, you may opt to go for in-line connectors, such as the one shown in Figure 1.įigure 1: A two-pole “Eurostrip” HE4WPR/02 from ALtech (Source: Digi-Key online catalog) Bearing all of this in mind… In-line connectors An insurance claim for an unrelated fire was rejected by the insurance company because the pot light installation was not to code. For example, a friend had pot lights installed by some contractor at the lowest price. These standards are there for a reason, and you ignore them at your peril - sometimes in unexpected ways. Also, a join between two wires can add a significant series resistance, especially if it is not a good connection, and so, in the extreme, that joint can get very hot.ĭepending on the voltage and the current, there are standards that govern these connections. The thinnest wire must be capable of carrying the maximum current of the circuit. Often, the wires differ in gauge and form (i.e., solid core versus stranded wire). Let me start out by cautioning the reader: Just because you can connect two wires together, it doesn’t mean that you should connect them together. Based on this, I hope that other members of the EEWeb Community will add their suggestions in the comments below. I documented tidbits that I gleaned on connectors working on several projects in the industrial sphere over the years in two blogs: “ Which PCB Connectors Are Best?” and “ Unusual connectors.” The point is that this kind of exposure may possibly limit my knowledge as to all of the different ways there are to connect two (or more) ends of wire. ![]() Let me make a disclosure here: I once worked for a large German connector company, and my current employer is a spin-off that maintains close “connections” with said company. ![]() The connections look permanent and tedious to complete, while my own experience is one that favors speed with the possibility of re-connection. My first thought was, I hope the power is off!, followed by, This looks like finger blisters to me. In a recent blog - “ Best Way to Twist Electric Wires Together” - our illustrious editor-in-chief and principal bottle washer, Max (the Magnificent) Maxfield, described several unaided ways to attach one wire to another. Just because you can connect two wires together, it doesn’t mean that you should, but if you need to, then here’s how. ![]()
