Conditions of installation:

Ambient air temperature: 30°C
Ground temperature: 20°C
Maximum conductor temperature: 90°C

Where a conductor operates at a temperature exceeding 70°C it must be ascertained that the equipment connected to the conductor is suitable for the conductor operating temperature (see Regulation 512.1.2).

Where cables in the above table are connected to the equipment or accessories designed to operate at a temperature not exceeding 70 °C, the current rating given in the equivalent table for 70 °C thermoplastic insulated cables (Table 4D4A) must be used (also see Regulation 523.1).


Suitable gland types:

CW CIEL – Brass: Internal & External
