Q: How often should isolator switches be inspected?
A: Per manufacturer recommendations, annually at minimum or more frequently for higher voltage switches.
Q: What are signs an isolator switch needs maintenance?
A: Overheating, arcing, stiff operation, corrosion, loose connections, cracking insulators.
Q: What routine maintenance should be performed on isolator switches?
A: Lubricating joints, cleaning, tightening connections, testing operation.
Q: How do I lubricate an isolator switch?
A: De-energize, clean surfaces, apply recommended conductive lubricant, allow to dry before re-energizing.
Q: What tools are needed to maintain isolator switches?
A: Basic hand tools – screwdrivers, wrenches, pliers, wire brush, lubricant, gloves, safety gear.
Q: Where can I obtain replacement isolator switch parts?
A: From the manufacturer or electrical distributors that supply OEM replacement parts.
Q: How do I safely inspect a high voltage isolator switch?
A: Follow strict safety procedures – de-energize, lockout/tagout, discharge stored energy, use proper PPE.
Q: Can faulty isolator switches be repaired?
A: Minor issues can be repaired. Major problems usually require a full replacement.
Q: What isolator switch accessories aid maintenance?
A: Manuals, labels, lubricants, replacement contacts, insulators, operating handles.
Q: How can I tell if an isolator switch has been operated too much?
A: Count operations against ratings. Inspect for overheating or contact pitting/oxidation.
