How to ground two pron or slot outlets

Grounding ungrounded outlets

Most 2 prong outlet cannot be grounded. There was a time in the late 1950 and early 1960 where outlet boxes were grounded but the outlets were not. In this those situations it is possible to pigtail a wire from inside the box and add a grounded outlet.

Older wiring type can only be grounded by running new wires. If your outlets are from before the 1950's you really should plan on having them rewired. I would not trust the safety of 60 year old wiring and I certainly would trust it less and less as the wiring turned 70&80&90& so on.
