You need to pull four 10 AWG THHN wires and two 12 AWG THHN wires through EMT. The calculator will sum the cross-sectional areas, apply the 40% fill rule, and recommend a 3/4" or 1" EMT depending on spare capacity.
The NEC provides guidelines for conduit sizing in Chapter 9, Table 1. The calculator will take these guidelines into account. However, it's essential to familiarize yourself with the NEC requirements: electrical conduit size calculator
const totalWireArea = computeTotalArea(); const numWires = wires.length; const fillLimit = getFillPercentLimit(numWires); const requiredArea = totalWireArea / fillLimit; const spareMultiplier = 1 + (sparePercent / 100); const finalRequiredArea = requiredArea * spareMultiplier; You need to pull four 10 AWG THHN
Using the National Electrical Code (NEC) standards, specifically Chapter 9, is required for passing inspections. The Core NEC Fill Rules The calculator will take these guidelines into account
