ESD-safe item requirements
(Excerpted from RCJS-5-1)
Item-specific requirements
In some cases, the max. EPA ground resistance is increased (usually by
1 X 106Ω) for every 250 VAC or 500VDC in order to ensure a minimum
resistance of 7.5 X 105Ω. The resistance must maintain a 1/4 W
minimum power rating per each 250 VAC or 500 VDC.
