These current and voltage drops data are indicated for continuous duty operation
They are as defined in BS 7671 : 2001
table 4D2A and apply to
- maximum conductor temperature = 70oC
- nominal frequencies = 50 - 60 Hz
On cable in air, clipped direct at ambient temperature = 30oC
Voltage drop
The data is based on Cos j = 1
For other laying conditions, refer to BS 7671 : 2001 standard |
