What does the term 'fire load' refer to in cable ratings?

• A. The Amount Of Energy Released During Combustion.
• B. The Color Coding Of Cables.
• C. The Voltage Rating.
• D. The Physical Size Of The Cable.

Answer: (A)

Fire load is about the energy released if the cable’s insulation and jacket burn. It measures how much heat the material could contribute to a fire, based on the material’s calorific value and the amount present. This helps assess fire risk, flame spread, and related safety requirements in codes. It’s not about color coding, voltage rating, or the cable’s physical size, which are separate specifications.
