In the past, the UL508A standard only required “RECOGNIZED” terminal blocks to be used in feeder circuits. But today, UL has updated their standards to require “LISTED” power distribution blocks with increased spacing to be used.
Marathon Special Products’ 134, 135 and EPB series provide a cost-effective solution for feeder circuit compliance.
