How Many Wires In Conduit Before Derating at Shirley Arrowood blog

How Many Wires In Conduit Before Derating. It must be large enough for the largest circuit. both circuits can share 1 ground wire in conduit. our nec conduit fill chart calculates thwn and thhn wire fill for emt, imt, rigid metal, or flexible metal conduit pipe using. That will only give you about 33% conduit fill on a 1 conduit with thhn wires. the app will calculate the conduit fill percentages and jam probability for multiple conductors per nec® guidelines. Remember current only flows on ground. conduit fill and environment are cumulative, so you’d have to derate the capacity of the wire by multiplying by a fill factor and also multiplying by a temperature factor. you need to bring in six #6 wires and 1 bare ground wire up to #6. Concurrent factors also apply, but they’re separate. if you use some mwbc's you could get up to 9 circuits before derating would put you below 20 amps depending.
