Which of the following is NOT excluded in the equipment breakdown basic policy?

The correct answer indicates that the explosion of steam boilers is not excluded in the basic policy for equipment breakdown coverage. This type of coverage is specifically designed to address incidents that can disrupt the normal operation of a business due to mechanical or electrical breakdowns.

Equipment breakdown insurance typically includes coverage for various types of equipment and machinery, and the explosion of steam boilers is a significant risk that is explicitly covered. This is crucial for businesses that rely on such equipment to operate, as the consequences of an explosion can be catastrophic and costly, leading to potential physical damage and significant business interruption.

In contrast, the other options reflect types of coverage or exclusions that might not be included in the basic policy. Ordinance or law coverage, business interruption, and loss of power or refrigeration might be excluded or require additional endorsements since they can fall outside the scope of standard equipment breakdown insurance. Understanding what is included and excluded helps businesses better assess their risks and need for supplemental coverage.
