Thefloodlights draw 15 amps of current. The length the wire needs to be to connect to the floodlights is 9 ft. Based on the chart above, you would want to use 12
Examplefor the calculation of the current carrying capacity. five loaded cores and laying in three layers on a motor drum is required. Tables of VDE 0298-4 to be observed: Table 10, 11, 18, 27 and 28. Current carrying capacity for a nominal cross-section of 4.0mm² at up to +50°C according to tables 10and 11/5: 34A.
Inour wire resistance calculator, we have listed some materials, which you can select to find their resistivity and conductivity at 20°C. For example, the electrical conductivity of copper is σ ≈ 5.95 × 10^7 S / m , and the electrical resistivity of copper is ρ ≈ 1.68 × 10^(-8) Ω × m .
GroundWire Size Calculator. The Ground Conductor Size Calculator will calculate the proper ground conductor size for grounding raceways and equipment based on ampere rating or setting of automatic overcurrent protection device in circuit ahead of equipment. This is based on NEC NFPA 70E Table 250.122. Search Amazon for your Electrical
BySteven McFadyen on April 9th, 2012. IEC 60228 is the International Electrotechnical Commission's international standard on conductors of insulated cables. Among other things, it defines a set of standard wire cross-sections: International standard wire sizes (IEC 60228) 0.5 mm². 0.75 mm². 1 mm².
