I think this can now be put to bed – I have checked with RUHR/CES about the 80% figure, it came from CES as an estimate of liberal power usage during an outage (i.e. – power consumption during an outage is likely to be less than 90kVA at all times and, if usage ever does go above 100kVA, the generator breaker will flick itself off).
I suggest I sign off on this now, if there are any further concerns they can be brought up in tomorrow’s meeting.
Best regards,
