Re: ungrounded wall outlets

said by KLH:

Wouldn't just connecting the neutral to ground to safer with a 3 prong outlet?

Safety ground is designed to provide a low impedance path to trip the over-current device in case of a fault to normally non-energized part - typically a metal chassis or tool housing.

Think about the ramification of your suggestion. If you tie Neutral and Safety ground together and Neutral ever faults open now those parts are at line potential.

In a dwelling without safety ground the best you can do is use Ground Fault breakers or outlets. They will trip if there is an unbalance between hot and neutral.
