Late Entry: Earlier today, the breakers for Arc 5 and RSEP8 were swapped. The current trip limit was lowered to 800A and the LD (Long Delay) Fault was increased to 5 seconds from 2 seconds for RESP8 (formerly ARC 5). Both SAM 1 and NAM 1 were restored successfully. The box supplies in both buildings were powered up, settings restored and cycled successfully.
The breaker which tripped four times when supplying the Arc 5 power supply was swapped with the same style of breaker supplying RSEP8A this afternoon. It just tripped in its new location. Beam can only be supplied to Hall B until the breaker is replaced. The distributor and manufacturer cannot provide information until Monday. FML SME hazarded Wednesday as earliest possible fix and could not provide a not-to-exceed date. Pass three beam is accessible if it's of any use to anyone.
