Yet it is possible to retrofit a new three-prong or GFCI receptacle into the same outlet box without any rewiring, as long as the box itself is grounded. Old-fashioned two-prong receptacles, also known as outlets, connected to two-wire cables don’t have the ground wires that protect people and electrical devices in case of a fault. sells a common wrist strap for $1.N/A Can You Install a Three-Prong Outlet Without Ground Wires? So far everyone has been pretty spot on and I’ve probably ever seen professionals utilize the anti-static grounding straps/ wristbands. Touch a metal object using another metal object to release static discharge.”Īnother tip is included about preventing damage to electronics and computer parts by storing them inside anti-static bags to mitigate any damage from encounters with static charges during handling, transportation or storage etc.Avoid wearing clothing made from wool and synthetic fabrics.Increase humidity levels in your environment. Grounding Yourself Using General Techniques Handle all components by their edges when installing and removing them from your machine.Verify your computer is unplugged or turned off before working on its components.Stand on an anti-static mat when working on your device.Wear an anti-static strap or wristband.Touch a grounded object before starting work on your computer or electronic device.Remove trash and other unnecessary items from your workspace.Work in an environment with humidity levels between 35 and 50 percent.Set up your workspace in an area without rugs or carpet.If You view the link provided you will also notice that there is more detailed information available about each of these steps with illustrations provided as well! Here are the headings/titles for the steps described (taken directly from WikiHow): I have included the 13 steps (in total) that make up both methods. You’ll notice that there are two methods discussed however “method one” most directly applies to the question originally posted by mayer. WikiHow has a fairly comprehensive and detailed set of steps that can be taken to help ensure that you are grounded and that there is not a harmful discharge of static electricity while working on electronics. Also, if there is a chance that you could get shocked, make sure the shock does not go through your heart, ie hand to hand, hand to feet or any combination of. If it's in your left hand, it can't be plugged in. Always remember the Left hand rule, that is make SURE plug for the device you are troubleshooting is in your left hand. Remember as someone mentioned above, it's all about potential from point A to point B. (not much) If you go beyond 100 to 200 ma your gaming days are done. Your heart is sent a "message" via sodium/potassium gate generating between 10 and 100 millivolts. Just remember, current going from arm to arm or arm to leg passes through your heart. Grounding straps and mats are not that expensive and well worth their money if you are working on very low current components. (the device does NOT need to be powered up, just plugged into a grounded receptacle.) There again so long as the grounding of the device are intact and you have less than 5 ohms from the grounding pin to the metal chassis. If you need earth ground, you could plug in that device and touch the metal portion of that device, that should also ground you. Knowing procedures, you can quickly overcome this "electrically potential" problem. Using your "earth" ground point with components you can actually create a "floating ground" which means a voltage potential. This is where the grounding pad would come in keeping all voltages the same or no potential difference. or no voltage difference from one to the other. Remember, we are looking for your electrical potential to be at the same as the device you are working on, hence, NO POTENTIAL. Attach one side of the wire to a metal piece of the chassis of the affected device you are working on. From there, fold up some aluminum foil, attach the wire to the foil and wrap the foil around your wrist. Remove several inches of the stranded wire. In a pinch, you can make your own grounding / bonding wrist strap by stripping off a length of wire. There's some good advice here but I'd like to add my two cents.
