Cell Phone Carrrier SIte ....Site has 5 meter loops on bussed wire trough. we are only able to acquire Peak Load from 1 site and getting remaining Peak loads from other carriers has been difficult. Customer wants generator to operate all five carriers at once during outage. Any suggestion on how to establish load for rest of equipment onsite? We could record readings for 30days but any suggestions on how to get information needed. All Carriers are aware of but not really cooperating.
