"One way to determine the low frequency effectiveness of a ground is to
connect the hot side of the power mains to the ground through a fuse and
see how big of a fuse you can blow."

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