I am talking about 200-300 dollar power connectors that are cast aluminum with pencil size stab posts.
I just replaced my total pigtail to my excella and it only took about ten minutes. I now have the molded head where the wires can't move around when you drop the head on the ground or into your bumper box.
1. its an outdoor connection
2. Its 220V
3. It can go phase to phase inside the aftermarket connector and blow out
4. The wiring can be stressed and pulled on if there is a stiff connection.
5. Then you can make a new extension cord with your old pigtail and use the after market connectors. It will not see much use but you have it if you need it. I would check these at least yearly.
This was my first thought but after searching these don't appear to be
readily available. Where did you get yours?
I know in molded plugs the spades are soldered to the wire. I thought
about doing this with an aftermarket plug after putting the screws to it. I
spoke to my father about this who is also very leary about the
aftermarket plugs. He used to work at the local state fairgrounds as the ME and he
said "You have no idea how many of these plugs melted and smoldering
because of a loose connection on the screws."
I guess my other option is to upgrade the trailer to a 50amp connection
and rebuild the panel inside. If I did this I would have to replace the panel,
rewire the inverter to only one leg of the panel and then I could run
everything at once with no problems.
