The bought ones come with a resistor I was involved in adding a resistor to the ground line. Explosive workers at the Navy Base where I worked wanted to not be a direct short in case 110 VAC was encountered. Navy safety said about 2 ma would be safe. So we added a 50K resistor. Industry all started adding a resistor soon after. The problem with shocks is if it is one side to ground you can take a bigger shock where across the heart 4 ma may be deadly. One of the reasons animals are killed from lightning ground currents. We get shocked leg to leg where the animal leg to leg crosses its heart. So when grounding yourself make sure you do not have a current path across your heart. Friends who would not listen to what I said about health are not dead yet but are wheel chair bound. Last winter in a RV Park hot tub several ladies could not believe that I am nearly 80. I didn't even begin to tell them about EIS as I found it goes on deaf ears unless they ask. Brickey
