Recommended Replacement for Parallax ATS 5070 Shore/Generator Line Switch

[Mattturley]

Hi All,

Saturday night I was laying in bed when I smelled electrical smoke, shortly thereafter I saw arching and lost power. I ran out and disconnected from shore power, and am OK running on Generator now, though I don’t want to do for too much longer, as the picture shows I am not comfortable with it.

Turns out I lost the neutral, and it melted through the bridge bar (picture). I was hoping to replace the bridge bar, but I cannot find one even at an in person State Electric Supply, and digging through catalogs with their guys.

Looking for recommendations on best replacement for the ATS 5070.

Also, the only thing that will burn a neutral line like this is either a loose connection, which best case scenario would have been at the bridge bar itself, or a ground fault down stream. Connection in the panel is tight and clean.

Metered the generator production at panel and still coming in cleanly at 121 volts. Before I found this (pictured), I metered shore power around 32.

The only other clue I have is that the brand new house batteries were dying even when plugged into shore power if I left for a few weeks. Recommendations on the wire routing from the line/generator switch to the step down battery charger and where is that charger located?

Thanks,
Matt

I think I see what and where for the answers but first need to check that you are the RV I think! I think I see a 10 and 12 gauge at far right as feeding from the transfer switch to the load center?
That likely means a 30 amp main breaker but there are two versions of that coach. To be more sure of the right drawings, can you check that the load center has 8 breakers with the five at right side being all 15?
Or do you have 9 breakers and end with the far right being a 20amp?

Click for better view!
This breaker panel?

Or this?


I see it as being a separate stand alone converter that is fed off the load center transfer switch like this? near passenger side with the front to left on this drawing.


But is that the burned wire? I think I see that as the power cord white neutral as the one that is cut off?

Or am I missing why you ask?
