That’s important to highlight, since some people falsely think that by just modifying a two-prong plug into a three-prong plug, the cord will already be considered grounded. Where will the extra current surge flow if there’s no ground wire? It’s just one part of the safety blanket, after all. You have to remember that it’s not so much the presence of the prong that matters. those that aren’t medium or heavy-duty).Īre all three-pronged cords considered grounded?

Ungrounded cords are far riskier to use than their grounded counterparts. Have you ever entertained the thought of removing the ground prong on a plug? I hope you block it out for good because doing so is equivalent to putting yourself in direct danger from electrical shocks. Two-prong appliances, especially double-insulated ones, should be fine as well. It’s only safe to use ungrounded cords with light-duty, simple appliances like alarm clocks and small lighting fixtures, assuming you’re sure that the devices are still in good, working condition.

You have to use a grounded outdoor or indoor extension cord for any tool or electrical equipment that needs grounding.

When should you use a grounded extension cord? However, grounded extension cords do not so much provide direct electric shock protection as they help to prevent most appliances from becoming natural shock hazards when you touch them. Yes, they’re grounded precisely for that purpose. FAQsĭo grounded extension cords protect from electrical shock?

Only a ground wire in an extension cord or proper insulation can prevent them. Typically, they happen because the appliance’s wires come in contact with its casing. Lastly, you may be wondering what causes the electric shocks in the first place. This underscores the importance of knowing which type of extension cord to use (two-prong or three-prong) based on your appliances’ individual loads.

If you plug an appliance that needs grounding (such as fridges and dishwashers) into an extension cord that isn’t grounded, then you’re inviting electrocution.

Once they do rear their ugly heads, though, you’re in for a literal shock! Usually, faults occur if the appliance you plug into the extension cord exceeds its wires’ rated ampacity.

Ungrounded cords should also work if there are no fault conditions that happen as you’re operating the appliance.

There are numerous scenarios to consider to answer this question correctly and in detail. What Happens if the Extension Cord Isn’t Grounded? It’s only right that they should be integrated with the necessary protective capabilities with regard to grounding as well. Overall, we rely a lot on extension cords to address distance issues when powering our tools and appliances. This rings true for any plug that’s grounded, extension cord or otherwise. Technically, it’s the ground wire and prong of the cord that “unlocks” the advantage and purpose of the said outlet type. Of course, a 3 prong extension cord has to be plugged into a grounded outlet to work properly. Usually, these are the typical metal-encased ones that also come with a grounded plug. The reason why there’s an extension cord ground prong is mainly to ensure safety while operating any grounded appliances connected to it. These electrical issues may even become fire hazards at times. It’s a given that we all want to prevent electric shocks as much as possible from occurring in our homes. Why Do Extension Cords Need to Be Grounded? It contains both the hot and neutral wires connected to the right and left prongs, respectively, but it also throws in the additional ground wire connected to the said middle prong.Īn extension cord without ground or one that’s two-pronged and not double-insulated fails to impart this valuable safety benefit.

What Happens if the Extension Cord Isn’t Grounded?Īn extension cord with ground or one that has a middle prong, as some folks like to call it, prevents the risk of electrocution that may arise due to a short circuit and other fault conditions.Why Do Extension Cords Need to Be Grounded?.
