I faced a similar problem, and built a D-I-Y leakage meter.

That's very interesting. Once I've replaced my RCD, I may use the old
one to build a similar device. Thanks for the information.

I've already got a megger (albeit a fairly cheap one). It's good for
checking insulation resistance, but it doesn't allow me to measure the
earth leakage under operating conditions like the device Ron describes
would.
