This calculation does not take into account the heat dissipation from the switch gear. Selection of insulated braided conductor IBS, IBSB & IBSBR according to the internal temperature of the panel. Temperature rise of conductor = T2 - T1 = ∆T (K) Ex.: For a current of 630A, with: T1 = 40ºC - T2 = 90ºC 1) ∆T = 90 - 40 = 50K 2) In the 50ºK column, find the closest current value to 630A. K = Kelvin degree (temperature calculated, but not measurable.) Internal Temperature of panel (T1) Temperature of conductors (T2) Ambient Temperature Insulated braided conductor in parallel When using 2 or 3 insulated braided conductors in parallel for the same phase, use the current coefficient: Ex.: IBSB 100 - ΔTº = 50K: 385 A 2 braids in parallel > 385 A x 1.6 = 616 A 3 braids in parallel > 385 A x 2 = 770 A 30 www.erico.com
