Current indication

Evening all, 

A client has asked if I can have an indication (from within the house) of when the septic tank pump is running, just for the peace of mind that they know that it does actually work!, I can't see anything obvious in terms of an off the shelf product, I'm thinking I would require a type of current monitoring device and a simple light indicating the pump is 'on' or even a figure confirming the amps being drawn. Any suggestions appreciated.

  • +1 for a "current sensing relay" approach - they're commonly sold as load shedding relays and you see them incorporated into shower priority units. Usually DIN rail mounting modules, it's easy enough to put them in a simple DIN rail enclosure and wire them up to any indicator you like (you can even get DIN rail mounted indicator lamps, which might be convenient). I've used one in a box along with a couple of trailing sockets to switch on a vacuum cleaner when a power tool is used. Just be careful of the specification and that it'll actually switch with the load the pump presents - some cheaper ones only kick in at about 6A.
