4.1 FINAL INSPECTION
1. Verify all cables / conduit runs are secured with zip ties or other non-conductive cable
clamps to prevent damage from vibration.
2. Ensure all cables that pass through walls, bulkheads or any other openings are protected
against abrasion by using strain reliefs and/or grommets.
3. Check all AC, DC and ground connections are securely tightened, and if required covered
with suitable anti-seizing grease.
4. Check all connections are secure in the main and sub panels - replace all covers.
5. If required by code, have the installation inspected by an electrical inspector.
