The white paper was developed by the NEMA Industrial Automation Control Products and Systems Section (1IS) Subcommittee on Adjustable Speed Drives (SC7). It provides clarification to prevent attempts to apply non-relevant requirements to NEMA member products.
According to NEMA SC7 Chairman Dan Stewart, “As the drives industry transitions from UL 508C to UL 61800-5-1, integrators and end users may notice changes in drive SCCR’s (Short Circuit Current Ratings), recommended branch circuit and overcurrent protection devices, and/or requirements for supplementary enclosures for some drives. This white paper provides relevant background information.”
