Wayne Hobbins The appliances are mighty sitting upon their drawer option with the latest electronics less the notify via phone. So even looking at the appliance with tools in hand would land me in the seat with my wife and lawyer sitting across the table.

Wayne Hobbins Da wife has been showered with every creature comfort know to man. So sir I take me white glove and challenging slap you once from left to right and once in the opposite direction.

Having the dog duty sounds promising but think she lacks the attention span. Don't think I could her to count "woofs" <-is that a thing?

Anyhow you are trying if that is your best I can expect great things from you my friend.

I did not know this about clip on CT senors looks like I will need the diode included unit and hope it never fails and I have an open circuit on the secondary.

In general, a CT must never be open-circuited once it's attached to a current-carrying conductor.

A CT is potentially dangerous if open-circuited.

 

If open-circuited with current flowing in the primary, the transformer secondary will attempt to continue driving current into what is effectively an infinite impedance. This will produce a high and potentially dangerous voltage across the secondary [1]

 

Some CT's have built-in protection. Some have protective Zener diodes as is the case with the SCT-013-000 recommended for use in this project. If the CT is of the 'voltage output' type, it has a built in burden resistor. Thus, it cannot be open-circuited.
