Can a fire resistant cable be used and installed in very hot environments, for example, very close to a furnace?
No, a fire resistant cable with a fire rating does not necessarily mean that it is suitable for use in a hot environment. For cables used in hot environments, a heat resistant cable is recommended. These cables are with special insulation and sheath materials such as silicone. teflon or glass fibre to withstand relatively high temperatures (in excess of 110°C) on a continuous basis.
