If there is more current than the connector is designed for, or the wire is rated for at that diameter, there will be excessive voltage drop. (Such as pulling 30A through a 15A connector.) Even if the connector was properly installed.
Secondly, was that one you tested an actual Anderson product, or an off-brand?
Actual Anderson Power Pole parts and NOT off-brand as you call it.
I was using the 30A parts and current drain could not have been any near that
since i was only using a receiver specified to draw about 3A. Apparently you
think I do not know what I am doing and my 40+ years of being in various
electronics industries as an electronics engineer are worthless. I am well aware
far more than you are when it comes to measurements standards and how to
go about them. PS - Anderson Power Pole crimp connector was used to put it
all together. Don't you have anyone else to harrass or puke on?
