Fire rated cable is designed to maintain circuit integrity during a fire, ensuring critical systems like alarms and emergency lighting keep working. It's a safety essential in buildings, often running through fire-resistant walls. The cable's insulation and jacketing are tested to withstand flames for a set time, preventing short circuits and keeping control in a crisis.
