Anyone here know if a manufacturer like Burndy or the like makes wire reducers, for reducing larger size wires at large breakers?. I somewhat remember using them years ago, but am not sure. This part of the latest project has 4 parallel runs of 3-750's, sized for the distance, terminating at a 1200 amp 3-pole. The breaker was sent with provisions for up to 4- 500's per pole. Its a Seimen's "Sentra" Breaker.I think I remember being able to get hyd. press on reducers with a solid end that would fit.Just not sure if they are available in that size.Any thoughts?
