'AC In' connector replacement.




I have received the WAGO 221-412 and 221-2401 connectors in the mail. Those have replaced the wire nuts traditionally used to tie two household grade wires together, typically 12/2.


I have removed the connector sub-pcb and unsoldered and removed the damaged connector using the solder iron, solder, solder sucker and flux paste.The pcb is ready for the new WAGO 2606-1103 connector. I added two push-fin cable strain relief clamps for the AC connections.

I received the new connector a couple of days ago. Preparations included setting up the new soldering iron plus solder, sucker and flux paste. The replacement went smoothly. After the replacement, I re-assembled the unit and removed the 1200W unit. I attached the 2000W unit to the wall after attaching the AC and DC cables.

I started the unit this morning and all is well. 


The final test will be the attachment of a running inverter/generator like the Predator 2000 to test shore power detection and switching.
