Which of the following causes of loss is NOT excluded in an Equipment Breakdown Protection Coverage Form?

In the context of an Equipment Breakdown Protection Coverage Form, mechanical failure is included in the coverage and is not excluded. This type of insurance is specifically designed to protect against losses arising from the breakdown of machinery and equipment, which can include mechanical failures. The policy typically covers failures that might not be addressed in standard property insurance policies, making this coverage essential for businesses reliant on machinery.

The policy could also extend to situations like electrical testing, which is usually involved in identifying issues with equipment. In contrast, causes like combustion explosion or hail would generally fall under standalone exclusions found in many equipment breakdown policies, as they pertain more to external forces or incidents that can affect a structure rather than the specific malfunction or breakdown of equipment. Hence, mechanical failure remains a covered risk within the framework of equipment breakdown insurance.
