T&T: portable watt-hour meter

[JHWardJr at aol.com]

The Kill-o-Watt is a home device that connects between an outlet and the  
suspect device.  It can only handle 1500 watts, but with adapters  theoretically 
will work on your shore power cord as long as you keep the  draw under the 
limit.  Mine did not read accurately in 'whole boat' mode  for some reason.  
 
It is a great way to do what you ask.  You can shut off all but the  measured 
device and see what the pedestal reads.   Note that some  meters seem to have 
a 'wrap-up' - reads nothing for a few kwh's and then zing! -  adds several 
very quickly.  We have notoriously inaccurate pedestal meters  here and the 
power usage is all over the map.  Good luck!   Jim

I would  like to double check my marina's watt hour meter that's on my power
post.  Ideally I would like a meter that would plug into a 50 amp 125/250
outlet  with the same outlet, or split to two 30 amp plugs. I could also use
two of  these designed for 30 amp power cords. I found the latter, but
they're $250  EACH.
