Posted on a wood worker forum on April 18th and his result figures are
7 amps higher because he did not subtract the 7 amps that the box draws but
is not recorded by the "Utilities Meter". For example the
Cyclone pulled 26A w/o the box and 24A with the box ) should be 17Amps.
Well, I am no power expert, and
thought I would try out this crazy thing. You connect it to the panel box and it
will save you money....... Yeah right I thought........ Well..... Maybe it will
after all!
Here is what I did. Connected to breaker that supplies my 5HP compressor. I then
turned on various equipment in my shop and used a clamp on amp-meter to measure
the current in one leg of the single phase power in my shop. Here is what I got.
All equipment off, Shopbot on but not cutting, lights on etc... I pull 15A. With
this box on, I pull 13.5A. My 18" wide belt sander showed 34A and them 28A with
box on. Cyclone pulled 26A and 24A with box on. cyclone, Table Saw, sander and
planer running I pulled 60A with box on 54A.
Not really a good test but at least I saw a difference.
Now if I receive a check from the power company next month, and not the usual
bill, I'll be sure to buy a round of drinks at the next ShopBot camp I attend.
If my bill is less due to this box, how will I know? My bill is different each
month so I have not good baseline.
Well, there you have it for what it is worth. Your millage may vary, void where
prohibited by law, and I don't think any electrons were harmed in the experiment
but I may be saving some. It did not improve my memory or any other part of my
personal life. My cut quality on my ShopBot stayed the same and I still have to
work for a living. I am not connected in any way with Lighthouse Enterprises
(Ward, the vacuum motor guy) which is where I got this crazy little box. Made in
the U.S.A. and CSA as well as UL approved.
