Does anyone know what the maximum amperage a 1/2" or 1/4" (diameter) aluminum rod can carry? It'd likely be a 2xxx or 3xxx series alloy if that matters.
I'm looking to carry close to 100a on a bar for some HV projects I"m looking at.
I'm assuming that, using the NEC guidelines for aluminum, at around 700a/sqin, a 1/4" bar with a cross-sectional surface area of 0.19sqin, could carry up to 130a or so using NEC standards. Would this be a good assumption?
