Re: (ET) Vacuum running, man does it draw power.



I have an elec-trak vacuum blower I bought new from Bill Gunn years ago.  Mine does not draw a lot of amps, perhaps 15-22 amps.  I can check the actual amount next weekend if you would like.  Reduces my range a  notably but nothing dramatic.

  If you're running a 90ah battery flat in 30 mins, your load is 180 amps! 
  That's HUGE.  Lead batteries do NOT like that kind of load.

A similar problem with snow blowing is why I have AGM batteries in my
Ox.  But there are some other issues.  Is an Elec-Trak wired with AWG 6
wire?  I don't remember.  AWG 6 is rated for 75A (with 90C insulation
and 20C ambient).  And isn't there a 90A circuit breaker?  Leaf
vacuuming is much more of a continuous activity than snowblowing and you
do it at higher outside temperatures, so overheating seems like an issue.
