Multicontact was the name of one of the original manufacturers which caught on. The letters ‘MC’ stands for Multicontact, and do not imply multiple contacts in the connector. Voltage is normally rated to 600 V in the US and 1000 V outside the US, and ingress protection to IP 67. Current rating specifications by one manufacturer are about 30A, with contact resistance less than 0.5 Ω. They will normally take AWG 10 or AWG 12 wires to crimp or solder. MC4 connectors Normally a tool will be required to disconnect, but in some designs tabs can be pressed to unlock and pull. MC2 and MC4 are again push fit types but have a positive locking mechanism and proper ingress protection as per IEC 29. MC2 and MC4 connector: positive locking and ingress protection NEC code was revised in 2008 to additionally require positive locking and ingress protection. These were what we call MC1 and MC3 connectors. Now those could be used by ordinary people. Essentially, these were rubber shielded jacks and sockets that would push mate. MC3 Connectors To overcome these two problems different designs were put on the market starting in about year 2000. Solar panels in series invariably exceed this. National Electric Code (NEC) forbids people other than trained technicians to handle naked equipment at more than 50 volts. MC 1 and MC3 connector Previously, the lead out wires of the solar panels would be screw tied to other panels or control equipment, in a simple junction box and would soon succumb to weather effects. But then a poisoned arrow hit that very vulnerable heel, and he died as predicted). When came of age he fought victoriously because nothing would harm him.
