Electrical schematics of some instrumentation systems may be needed to illustrate wiring details not apparent in P&IDs. Consulting engineer designs typically include these schematics with electrical design documents. In addition, vendor electrical equipment-related submittals, which show the exact wiring requirements for the specific equipment furnished on a project, typically are one of the last sets of submittals that are approved on complex projects. These key submittals have a direct effect on the actual wiring drawings needed for construction by the installing contractor.
