You can click through to FastQuote, our online quotation tool, to select a cable that meets your size and specification requirements. chart depicts at full scale the American Wire Gauge (AWG) size of copper and. When choosing 100 amp service wire size, remember that a 100 amp circuit at 240V can proceed up to 24,000W of electricity. These sizes are also used for direct burial.

In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8. Here is the full step-by-step calculation of how to determine the wire size for a generator: Divide the generator’s wattage by the voltage to calculate the amp draw. Typical sizes of wires for 100 Amp Service are 4 AWG or 2 AWG for copper wiring and 2 AWG, 1 AWG, or 1/0 AWG for aluminum or copper-clad wiring. 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. You’ll need to use 4 AWG wire if the distance between the breaker. Most homes have an electrical service of between 100 to 200 amps. Electricians use these wires when there’s significant space between the circuit breaker panel and electrical equipment (such as air conditioners), which is common in large commercial buildings. 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. Most 100-amp service panels require 2 AWG wire. Complete the sections below to calculate your results.

120 Volt, Conductor size (AWG or kcmil) Single Phase, Max 3 Voltage Drop.

Eland Cables' Cable Calculator can help you determine the most appropriate cable size for your installation against British and IEC standards. To determine the load, add up the wattage of all electrical devices that will be on the circuit and divide this total by the voltage of the circuit, usually 120 volts or 240 volts.
