When should a technician avoid wearing an antistatic wrist strap?
- when installing RAM
- when replacing a power supply unit
- when installing a hard drive
- when opening a computer case
A power supply unit or CRT monitor are both able to retain large amounts of power after being turned off. These types of devices are too dangerous to connect an antistatic wrist strap to. Antistatic wrist straps are commonly worn when upgrading RAM or replacing a hard drive.
