| Typical use | Main incoming supply runs, heavy three-phase motor or panel feeds |
Voltage drop sets the longest run before lights dim and motors struggle. BS 7671 allows 3% on lighting circuits and 5% on other circuits; on a 230 V single-phase supply that is 6.9 V and 11.5 V. At this cable's 2.8 mV/A/m, the longest one-way run is:
| Load | Lighting circuit (3%) | Other circuits (5%) |
|---|---|---|
| 40 A | 61 m | 102 m |
| 50 A | 49 m | 82 m |
| 63 A | 39 m | 65 m |
| 80 A | 30 m | 51 m |
Check your own load and length with the voltage drop calculator. Every 100 m of each core holds 14.2 kg of copper; cable is priced from the day's copper rate, which is why each size up costs more.
| Size | Current capacity, 2 loaded | Voltage drop | Copper per 100 m of core |
|---|---|---|---|
| 10 mm² | 63 A | 4.4 mV/A/m | 8.9 kg |
| 16 mm² (this cable) | 85 A | 2.8 mV/A/m | 14.2 kg |
Current capacity with two loaded conductors, BS 7671 reference method C, 30°C ambient. Same class 5 copper construction in every size.
