so now an isolated ground type recept. has no continuity between the yolk and the IGC?

thats interesting..i will have to take a look at one of them.

it only makes sense since the device is isolating the ground from the other grounded components.

they both have the same potential though since they are bonded at the Main OCPD.

i have seen so-called IG systems that were not connected correctly.

how do you tell if there is another connection to the IG ckt?

are the benefits of an IG to reduce the interference to electronic equipment?

they seem to be called for in commercial and medical facilities.

does the code require an IG recept or ckt anywhere?

thanks for the comments
