Wiring a Solar MC4 Connector the right way!

Loose wires cause fires!
It's important to use the right tools and methods to maintain the IP rating of these MC4 connectors.
As usual, we at Universal Skills what to share as much knowledge as we can, so Carl is going to show you.

An important note about connectors that isn't pointed out in this video, there's only 1 true MC4 connector, now made by Stäubli. All other "MC4" connectors are "compatible", but even that is an exaggeration. You should only use connectors (or cables) from the same manufacturer in your setup because every connector, essentially the mating pins, has different tolerances so you will create resistance with your wires and will also create a potential fire hazard. So for safety and better efficiency, don't mix connectors from different manufacturers. It's also a good idea to use a crimping tool designed for the manufacturer’s connectors.

Can you use closed-barrel pins?
