Should not exceed 70℃.
The normal operating temperature of household cables should generally not exceed 70℃. This temperature applies to most common household cable types, such as PVC insulated cables and rubber insulated wires.
The maximum long-term operating temperature of PVC insulated cables is generally limited to below 70℃ to ensure the safe use of the wires and extend their service life.
The maximum operating temperature of rubber insulated wires can reach 65℃, which is also a relatively safe upper limit.
These temperature limits are to prevent the wires from being damaged by overheating, thereby avoiding potential safety risks such as fire or electric shock. In a home environment, ensure that the wires are not overloaded to maintain their safe operating temperature range.
