Run it to earth

What does "run it to earth" mean? What is its origin?

I haven't heard that. Is it like "run to ground." Drive an animal into its burrow. From Merriam-Webster:

to ground
1 : into a burrow - The fox went to ground.
2 : into hiding - Might need to make a run for it and go to ground someplace. -- Edward Hoagland.

Need more context. Some people also use "earth" and "ground" in the electrical sense so you could say "Run the blue wire to earth" or "to ground".
