The effectiveness of this pathway can be verified using a ground resistance tester, which measures the resistance between the cabinet and the earth. Industry guidance suggests that the resistance should not exceed 25 ohms to confirm a low-resistance path for static charge dissipation. The goal of grounding and bonding is to achieve customer-targeted resistance levels. These low resistance levels allow fault currents to easily discharge into the ground, protecting. . But what exactly makes energy storage battery cabinet grounding requirements so vital? You know, it's not just about compliance. Grounding stabilizes voltage levels, mitigates stray currents, and protects against short circuits. I have searched the NEC and have read NFPA 497 (standard for flammable vapors and liquids) and find no mention of a ne ergy storage systems (ESSs),.
