Jeez I get some enquiries lately...
I need to price for a warning bell when demand exceeds 60amps ac.
I guess I would need to wire an ammeter, which somehow sends a signal to a relay which in turn would trigger the bell. Is there such a thing available, how do you search for such a device? Or will it need to be made to order?
I've found a wireless device where a couple of magnet type thingies fit arround supply cable, but it just gives a remote visual on current drawn and I guess it wouldn't work if transmitting through several walls.
What would the device be called ? Anyone any ideas for search queries
