The type of electrical wiring that is known to burn is combustible electrical wiring. This refers to materials that can catch fire and burn when exposed to sufficient heat or electrical faults. Electrical systems often incorporate various insulation materials that may or may not be combustible.

Combustible wiring is often found in older installations or in cases where proper materials were not utilized. Understanding the behavior of combustible wiring is crucial for safety in electrical installations, as it can pose a significant fire hazard. Proper installation practices, including the use of non-combustible materials where required, can greatly reduce the risk of fire incidents in both commercial and residential settings.

In contrast, insulated electrical wiring typically has protective barriers designed to prevent overheating and reduce the risk of fire. Non-combustible electrical wiring materials are specifically engineered to withstand high temperatures without igniting, while residential electrical wiring refers broadly to wiring used in homes and does not specifically indicate the combustibility of the materials.
