How much does residual current monitor RCM cost, from where?

They seem to have a readout of how much current is being lost to earth,
so could be used to see which appliances are leaking how much
(by turning them on and off)
if an RCM was installed bedore the fuseboxes..

I cant find one on ebay

The only type I have seen are the very high sensitivity clamp meters,
that you place around the phase and neutral to your appliance / circuit
/ whatever of interest. They then measure the (very small) imbalance if
present.

Not cheep mind:
