I searched high and low for a generic aftermarket terminal block that afforded a “common feed” to any-all screw terminals. If such a thing exists, I couldn’t locate one. All the terminal blocks I was able to find provide common feeds only for individual pairs of terminal screws, each in their own individual channel. Fortunately, there was an easy fix for that.
Forum member Fred H accomplished the necessary “fix effect” by (apparently) dremeling out the terminal block’s barrier ridge into a groove into which he inset (epoxied???) a metal strip which affords contact between both rows and all terminal screws. As shown in Fred’s photo here. (After which Fred replaced the purple wire with a thicker-gauge wire which he felt was necessary). I truly applaud Fred for his Ingenuity, as well as his Patience in fabricating this modification. That patient, I am not, LOL.
Here’s the “fix method” I used to accomplish the same thing. I only needed a small number of connects, so I bought a small 4-terminal junction block. I used little metal jumper clips that jump over and bridge the barrier from one terminal screw to another, vertically. I then used a very short jumper wire with two ring terminals to bridge the channel rows horizontally. Thus, any wire connected to any terminal then provides current feed to all terminals. Here is a line diagram that illustrates the common distribution connections.
A photo of my common ground block installation is shown on the next page.
Note that although I used a terminal block with only 4 terminal screws, the screw lengths are plenty long enough to attach multiple ring terminals to any singular screw if so desired, and the marine- grade terminal block and its screws are designed to withstand high-torque screw tightening.
