7 LOAD SCHEDULE
The drive sizes quoted are from a site survey by Ian Stark and have not been further
verified at this time. A survey of the existing switchboards has however been conducted.
Several installed loads have been noted as redundant and have therefore been excluded
from the load schedule. It is to be confirmed by ISCo that this is correct. The redundant
loads are :-
1. P3-18 (90kW)
2. Phosphoric Acid trace heating T909/T910
3. Full load currents are from generic tables and have not been confirmed from
motor rating plates
