Don't know, never measured it. Ground side goes back to the breaker 
panel ground through the EMI filter. Mains ground in this area is 
required to be two ground rods placed 8 feet apart and connected to the 
panel through a continuous/unbroken #6 wire loop with both ends 
connected to the ground terminal in the panel.
