4. Check each breaker compartment for bolted joints in the primary disconnect bars. Where
such joints exist, check the bolts for tightness.
5. Inside the compartment, check the contact areas on each primary disconnect bar or
cluster of fingers for foreign matter that may have accumulated. Clean those areas if
necessary with a clean, lint-free rag and isopropyl alcohol or acetone.
Be sure to apply a thin film of D50HD38 (Mobilgrease 28) to the contact areas for better
electrical connections inside the compartment
