Is a bootleg ground legal?
A false ground or bootleg ground is dangerous The National Electrical Code (NEC) allows existing two wire electrical circuits to use GFCI receptacles and GFCI circuit breakers to protect older wiring. The only requirement is that they be marked as “GFCI protected non- grounded”, or similar wording.
What happens if a 3 prong outlet is not grounded?
If a three-prong outlet is installed with only two wires and no grounding path, we call it an ungrounded three-prong outlet. … 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.
Is no ground wire dangerous?
Yes, absolutely. Ungrounded outlets increase the chance of: Electrical fire. Without the ground present, errors that occur with your outlet may cause arcing, sparks and electrical charge that can spawn fire along walls, or on nearby furniture and fixtures.

What happens if you do not connect the ground wire?
The appliance will operate normally without the ground wire because it is not a part of the conducting path which supplies electricity to the appliance. … In the absence of the ground wire, shock hazard conditions will often not cause the breaker to trip unless the circuit has a ground fault interrupter in it.
Can I install a 3 prong outlet without ground?
For example, ungrounded three-prong outlets can be installed; however, there are risks involved with using non-grounded three-prong outlets. Two-prong outlets have no ground wire, without which the risk of electrocution and appliance damage is substantial.
