RE: (ET) Tool receptacle

["Elie, Larry (L.D.)" <lelie ford com>]

Yes, the rating is low.  No, it isn't fused.  My guess is; they tested the 
failure mode, and the connector fails OPEN.  That means the connector IS 
the fuse.  That also explains why they used a little 20A connector.  
Ratings are interesting; as I recall, the rating is 150% for 1.5 hours, 
200% for minutes, and 120% for many hours at room temperature.  Had they 
chosen a bigger connector, they would have required a fuse.  BTW, all the 
accessories I have seen for the connector use 16 Ga wire.  20 A would be 
pretty warm...

On the Tripp-Lites; I contacted the vendor over a year ago.  I was really 
interested in the combined fast-charger/inverted.  I no longer need this 
sort of sophistication (got some 36V accessories, and improved the 
charger), but a better charger is just as important as a big inverter.

Yep, I have the homeowner's manual; I just didn't see a fuse and it blows 
my
mind (that's a good pun :-) that they didn't fuse an outboard outlet. What
happens if the chainsaw shorts? Melts in your hand?

That's technically a problem for me since the Elec-Trak's 20amp outlet 
plugs
directly into the outboard side of the Solarex charger. Thus if the charger
were to ever short, the full force of the tractor's battery pile would
incinerate the controller and cable. My panels and the rest of the shed's
power infrastructure are safe because they are behind a 20amp 10k AIR DC
rated fused disconnect.

I guess I'll just have to put in a second RK5 30amp disconnect box at the
plug end for the tractor, since it's technically an unfused power source.
And maybe a little sanity fuse in the tractor itself. This will make four
disconnect boxes on a simple shed.

Drat.

Chris
