Ed/Jon,I have a question about neutrals and grounds,there are 3 places that I go to events each year,all 3 have electrical boxes(square D,GE)that do not have the interior breaker covers but only the outer cover,these places expect the customers to snap in a breaker and hook up the ground and the neutral,which I do.By now I am sure that we are all thinking the same thing,how much insurance must the people have.I have seen on one occasion a box that had the ground and neutral connected together,I did not hook up to that box.My question is,what could happen if one did hook up to it and should I always check with an ohm meter neutral and ground.
