Is it safe to plug a computer into an ungrounded outlet?
In order to protect against surges, I found a product called Zero Surge which, according to a sales rep, “does not rely on the ground circuit for effective surge protection, so you can safely use them in ungrounded outlets, and their performance will not be diminished in any way.” Furthermore, Zero Surge products are ” …
Is an ungrounded GFCI safe?
Ungrounded GFCI Outlets Offer Less Protection
For one, though ungrounded GFCI outlets offer you some protection (the GFCI outlet will sense when there is a ground fault and shut off), they will not protect your electronics in the chance of a ground fault.
What can I do with ungrounded outlets?
You can fix ungrounded outlets by rewiring the electrical circuit or installing GFCI protection at the outlet or circuit breaker. Rewiring is the only option that will ground the outlet safely.
How do you protect an ungrounded outlet?
The easiest and most cost-effective solution available would likely be to add a GFCI protected outlet on the first outlet in this circuit. GFCI stands for “Ground Fault Circuit Interrupter”. You’ve no doubt seen these before at bathrooms or kitchens, and you can read more about these on a previous post here.
Can I use 3 prong outlet without ground?
However, most newer appliances require an outlet that has three prongs for it to be plugged in. This has led many homeowners to incorrectly install a three prong outlet without properly attaching a ground wire. This can lead to many problems including risk of shock and appliances suffering from power surges.
Will a surge protector work with an ungrounded outlet?
In regard to the question about whether surge protectors work on ungrounded outlets, the answer is “no.” Surge protection equipment typically uses components called metal oxide varistors (MOVs) to divert excess current into the ground line.
Should I use GFCI for computer?
It is OK to have the computer plugged into a GFCI, although it may not be preferable. Hard shutdowns, as would be the case if the GFCI tripped (and the computer’s receptacle is actually protected as @keshlam’s comment suggests), are not the greatest for computers.
How do you ground a 3 prong outlet?
When a 3-prong plug is plugged into the receptacle, the grounding wire is connected to the prong and provides a continuous grounding path from the appliance back to the breaker box. This grounding path serves as a primary safety means if there is a short circuit or other damage to the electrical circuit or appliance.
Can you put a GFCI on every outlet?
You can replace almost any electrical outlet with a GFCI outlet. Correctly wired GFCIs will also protect other outlets on the same circuit. While it’s common to find GFCI outlets in bathrooms and kitchens, there are GFCI outlet requirements.

Without the ground present, problems with your outlet may cause arcing, sparks, and electrical charge that can spawn fire along walls or on nearby furniture and fixtures. Health hazard. Ungrounded outlets pose real risk of shock to people operating the electronics and appliances plugged into the outlet.
Do GFCI have to be grounded?
A GFCI does not require a ground wire to work the way it should. GFCI offers protection from electrocution by tripping power off in case of ground faults detected across the hot and neutral outlet slots. As mentioned above, GFCI is very important for protection against ground faults such as imbalances in the current.
