1 MAINS DISTRIBUTION GUIDE

2 USEFUL MAINS CALCULATIONS & INFORMATION All calculations are for guidance only and should be used in conjunction with BS7909 guidelines. Watts to Amps v = 4.35 Amps v = 8.70 Amps v = Amps Amps to Watts Blinding Light Cable Colour Coding Yellow = 2m v = 2300 Watts v = 3680 Watts v = 4600 Watts v = 7360 Watts v = 14,490 Watts v = 28,750 Watts Generator KVA Ratings Results are based on a generator producing 400v 3 phase at 50Hz with a 0.8 power factor. Grey = 5m Blue = 10m Red = 15m 100 KVA = 80kw / 144 Amps 150 KVA = 120kw / 217 Amps 200 KVA = 160kw / 289 Amps 300 KVA = 240kw / 433 Amps 400 KVA = 320kw / 577 Amps Mains Cable Ratings - H07RN-F All calculations given are based on max Amps in free air. 25mm Cable Diameter = 142 Amps 35mm Cable Diameter = 162 Amps 50mm Cable Diameter = 198 Amps 70mm Cable Diameter = 256 Amps 95mm Cable Diameter = 314 Amps 120mm Cable Diameter = 365 Amps 150mm Cable Diameter = 422 Amps Purple = 20m Purple / Grey = 25m Green = 30m Orange = 40m Brown = 50m
