🔍 Key Concepts

• Planned maintenance vs. condition-based maintenance for electrical systems • Manufacturer’s recommendations and good engineering practice for insulation care • Risk of damage from over-handling or unnecessary cleaning of insulation

💭 Think About

• Is electrical insulation something that normally follows a fixed calendar schedule, or is it checked and then maintained based on its condition? • Could too-frequent cleaning of insulation cause more harm than good, or is it always beneficial to clean on a tight schedule? • Which option sounds like a professional maintenance policy rather than a joke or a rigid rule?

✅ Before You Answer

• Eliminate any choice that is obviously not a professional maintenance standard • Ask whether the Coast Guard or manufacturers usually specify an exact calendar interval for this, or leave it to condition and inspection findings • Make sure the choice you pick reflects safety, practicality, and realistic shipboard practice
