I have SPD in panelboard model# 560277YP25ACCG10 ASCO Libert and 510120YP16ACAJ20.

The breaker sizes are 30A but when asked for equipment grounding conductor sizes it says #10 ACCUGuide cable size or #6 ACCUGuide cable size. NEC 2014 does not require SPD to have equipment grounding conductor size?
