AC Power Monitoring Panel

This is one Ebay-ish looking hub. Price is nice though.

No audio alarm. Auto-translation of the only review:

Cons: the appliance is designed for large currents. More suitable for garage or workshop. It would be nice to restrict to 25A. 4 times Increased accuracy would be on small "revs". Theoretically, nothing complicated. It is enough to increase the number of revolutions in the transformer current four times and change the calibration factors (one option). But who will do it?
Pros: a wide range of operating voltages (80-260v). -High precision device. -Done neatly and soundly. -The appliance can be used as electrical energy meter. -After a power failure, the appliance saves in memory the last number of energy. -Possible also to use as a remote monitor power consumption.

Ummmmm

Hozabout getting s split donut with the right value and substituting?

That is a pretty neat AC VOLTMETER arrangement...

The problem might be however is routing 120VAC direct to the meter box... Having 120VAC routed around the RV trailer might get touched by something else...

The ones we always used had the DONUT HALL EFFECT sensor around the hot AC LEG cable and only very small AC Current is being sent down the smaller wiring to the meter unit. Of course we was running three phase 480VOLTS at 600 AC AMPS back in those transmitter field station days... When things was running normal we wanted to see around 130AMP AC current in each of the three phase legs haha...

Disregard my concerns - I see the DONUT HALL EFFECT sensor in the writeup link...
