Replace the fuse with*a light bulb. If a high-wattage light bulb burns
brightly, the earth connection is good at the power frequency.

Yet another calibrated screw driver approach. The undefined quantities
"high-wattage" and "burns brightly" characterise the accuracy of the
method.

There are simple and safe methods for passing a known or measurable current
through a ground system and measuring the ground system potential rise
above the general mass of earth... a bit of Googling will turn up far
better methods that some of those described in this thread.
