It's a lesson you can't stress enough times, but you will always still get
the Darwin Award contenders spouting off about it.

Thanks for all the helpful suggestions from the original post. Will do

The CTs are clip on devices and do not require the removal of the
incomming feeds from the main breaker.  The CTs are connected to a
transmitter device that is connected to a single pole breaker.  The
display device is plugged in to any outlet in the house and
communicates over the powerline to the transmitter device.

For most normally wired homes in the US with 240VAC 2 pole feeds, it
works very well indeed.
