[LeArc] Generator Question

Sat, 15 Mar 2003 22:40:51 -0600

I don't have any experience with these so this is basically conjecture.

I would think you could draw 250 amps or so, but you would need some heavy
wire to do it.  But I don't know how long you would be able to do it.  I'm
not sure what kind of duty cycle these generators are designed for.  It
would take a very large alternator to produce a continuous 250 amps of
current.  For the supply to be continuous, or 100 percent duty cycle, you
would need the gasoline engine putting out a constant 3 KW.  And I don't
think it will.

Again, I have no idea what I'm talking about.  But that has never stopped me
before.

Keep us advised of what you find out.
