Nice Brass Master padlock has been installed on the disconnect box!
I was worried about that shorting bar, since I've never seen this particular power
disconnect box at my local stores.. If the shorter went missing, I would be SOL.

My next project is to install an Energy Monitor. I hope to be able to measure
the wattage being used at different outdoor temperatures.

That should help me determine at what outdoor temperatures would it
be more efficient to burn oil for heating. (If any).

I've decided to use the Efergy Elite Wireless Energy Saving Monitor.
efergy.com | elite

The unit (a Whole house monitor from the UK) is equipped with a non-electrical-contact
current probe that measures magnetic flux from one of the 230vac
lines going into the Sanyo. It just clips over the wire.

(Looks a bit like this one, but it's black and a bit thinner).
Hey! I found a pic of one!

It plugs into a small transmitter that sends signals upstairs to the
receiver/display unit. (The Xmitter looks like a bar of soap)!



I'll have to add a spacer sleeve around the wire inside the breaker box,
to insure the probe snaps into a good fixed position on the wire.
Then, I'll turn off everything but the Sanyo, measure the wattage using
the electric company meter and calibrate the Elite unit to the meter,
using the voltage select function in the setup menu.

Such a simple plan.. What could go wrong.?.

Cheers,
Rich
