What is Rated Horsepower? A Comprehensive Legal Overview

Q: Why is rated horsepower important?

It ensures that engines meet safety and performance standards, especially in hazardous environments like mining.

Q: How is rated horsepower measured?

It is measured under specific conditions defined by the manufacturer, including production tolerances.

Definition & Meaning

Rated horsepower refers to the nominal brake power output of a diesel engine, as specified by the manufacturer. This measurement is important for understanding the engine's performance capabilities. The rated horsepower is determined under specific conditions, including a defined production tolerance. For testing purposes, the fuel pump calibration must be set within the range of nominal and maximum fuel tolerance specifications.

Legal Use & context

Rated horsepower is primarily used in the context of mining safety regulations, particularly for diesel engines intended for underground coal mines. It is relevant in legal practices related to occupational safety and health, where compliance with safety standards is crucial. Users may need to manage forms or procedures related to engine specifications and safety approvals, which can often be handled using legal templates from US Legal Forms.

Key legal elements

Real-world examples

Here are a couple of examples of abatement:

For instance, a mining company may need to ensure that the diesel engines used in their operations meet the rated horsepower requirements set forth by safety regulations. If an engine has a rated horsepower of 300, it must be calibrated correctly to ensure it operates safely and efficiently in an underground environment. (hypothetical example)

Relevant laws & statutes

Rated horsepower is defined under the Code of Federal Regulations, specifically 30 CFR 7.82, which outlines testing and approval standards for diesel engines used in mining. This regulation ensures that engines meet safety and performance standards to protect workers in hazardous environments.
