Do grounding wrist straps work?
According to results from testing performed by the NASA Interagency Working Group on Electrostatic Discharge (IAWG-ESD), it was confirmed that wireless wrist straps failed to prevent charge build up or to drain accumulated charge in order to prevent potential discharges.
Why would you wear a grounding wrist strap?
An antistatic wrist strap, ESD wrist strap, or ground bracelet is an antistatic device used to safely ground a person working on very sensitive electronic equipment, to prevent the buildup of static electricity on their body, which can result in ESD.
How does a grounding bracelet work?
How Does It Work. A static discharge from you travels to the wrist strap from a direct connection to your skin. That discharge then follows a path from the wrist strap to the cord and so on until it reaches ground and is safely dissipated.
Where do you ground an ESD strap?
Wrist Straps can be connected to an electrical ground line via an electrical outlet or clipped onto free-standing grounds (like a metal table on a stone floor).
What is a grounding strap?

Should you wear an ESD wrist strap when working on a computer monitor?
A resistor inside an antistatic wrist strap protects the technician in case something accidentally touches the ground to which the strap attaches while he or she is working inside a computer. Technicians should not wear an ESD wrist strap when working inside a CRT monitor because of the high voltages there.
Where do you connect ground straps?
There are actually multiple places where you can connect a wrist strap to in order to be grounded. Wrist Straps can be connected to an electrical ground line via an electrical outlet or clipped onto free-standing grounds (like a metal table on a stone floor).
Do you need a ground strap?
