![]() ![]() You can click through to FastQuote, our online quotation tool, to select a cable that meets your size and specification requirements. In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8. The cable size results for International standard cable are calculated from IEC 6: Low Voltage Electrical Installations, selection and erection of electrical equipment – Wiring systems and are based on 230V and 415V voltage drop. It covers Low Voltage armoured AWA and SWA cables, insulated cables including twin & earth and 6491X, and insulated and sheathed cables in both PVC and LSZH such as H07ZZ-F and SY cable. The size of the wire needed depends on several factors, including the length of the run, the amperage rating of the circuit, the temperature rating of the wire, and the. The results for British standard cable are calculated from BS7671 (18th Edition) Requirements for Electrical Installation, IEE Wiring Regulations, and are based on 230V and 415V voltage drop. The National Electric Code recommends that to wire a 100 amp sub panel 300 feet away from the main panel, you should use 2/0-gauge aluminum wire or 4/0-gauge copper wire. Complete the sections below to calculate your results. ![]() Thank you so much for reading this article on Aluminum Wire Vs Copper Wire For 100 Amp Service, hopefully you found it helpful and informative.Eland Cables' Cable Calculator can help you determine the most appropriate cable size for your installation against British and IEC standards. Also, aluminum wiring is a viable option for houses where copper prices are high, but the superheat requirement of aluminum wire limits it's use in some cases. To conclude this blog post, you have learned that #2 AWG is the perfect 100 amp wire size. Aluminum wire is less expensive than copper wire, but looks uglier when strung together A 100 amp subpanel installation requires 4 AWG copper wire or an equivalent of 2 AWG aluminum wires. Copper wire is more expensive than aluminum wire, but looks nicer when strung togetherĪluminum wire: Rated at 100 amps and can carry between 94-105 Amps of continuously loaded current. These two types of wires are similar in resistance and can be used interchangeably with no ill effects, though aluminum will cost less due to its lower material costs.Ĭopper Wire: Rated at 100 amps and can carry anywhere between 80-95 Amps of continuously loaded current.
