SMT Line-Uniform Grounding Resistance

Hello All,

One of our customers has specified the requirement to maintain uniform grounding resistance between conveyor to conveyor & conveyor to machine.

Required specification is <10ohms.

Do you have any insights about this requirement and suggestions on how we can comply considering the different equipment’s make and model.

Appreciate your guidance. Thank you

Rahul,

Your customer wants to make sure all the conveyors and equipment are grounded to the same reference point. If you connect them all to the equipment grounding conductor (facility ground), you should be okay. You could test conveyor to conveyor & conveyor to machine by touching a conductive part (metal) of one conveyor or machine to a conductive part of a different conveyor or machine. You could go down the line testing each piece of equipment to its neighbor. If each measurement is less than the 10 ohms you should be compliant.
