What's a low-cost way to add a meter to an 110V electrical circuit?
This circuit runs from my service panel to our well pump. I want to
know how much electricity the well pump uses. Are there replacement
circuit breaker blocks that have meter functionality built into
them? ...or would a vampire a meter onto the circuit cable so that
it's sitting on the circuit between the service panel and the pump?
If so, what product? Is this something I can do myself? (I'm
comfortable wiring light fixtures, outlets, switches, etc.)
Get a cheap ( analog ) bedside clock.
Set it to 12 o clock.
Connect it so the clock runs when the pump runs.
At the end of a week ( or a month )
the clock will represent the number of hours/minutes the pump has run.
Multiply watts ( on the motor plate ) times hours ( on the clock )
to get watt-hours.....

Hi,
If the clock ran more than 12 hours, then what?
There is a meter which count by the hour and it's fraction.
