Documenting Approved Electrical Material Substitutions
For every approved electrical material substitution, record the originally specified item, the approved replacement, the reason for the change, and evidence of written authorization from the required approving party in the project file and corresponding purchase order. Cost savings alone do not justify an unauthorized or noncompliant substitution. Complete records help prevent ordering errors and provide evidence of what was approved if an inspection or dispute occurs.
