Will a 3 prong outlet work without ground?

An ungrounded three-prong outlet increases the potential for shocks or electrocution, and prevents surge protectors from doing their job, which may allow for damage to electronic components.

Will a GFCI breaker protect ungrounded outlets?

A cost-effective solution (Using GFCI Outlets): These outlets are considered safe to install on an un-grounded circuit, and replaces those inconvenient 2 prong outlets. Also, if installed on the first outlet of the circuit, other outlets down-line on this circuit would also be protected which makes it cost-effective.

Should all outlets be grounded?

Risks of Ungrounded Outlets The risk of an ungrounded outlet is simple: Without the grounding wire present, overloads or other surges are free to follow their current wherever it takes them. This might be the appliance you're plugging into the wall, or it could be your hand as you go to plug said appliance in.
