Where EPB blocks fit
The EPB family runs from 115 A to 760 A. The body is enclosed, so the live parts sit behind insulation. Pick the block by the feeder amps, then the line side conductor, then the number of load taps per pole. Check the SCCR against the available fault current at the panel. Send that and we will pick the catalog number with you.
