I have 4, #4 awg stranded wires in 1-1/4" greenfield 70 feet long. Can I snake more wire in there?
My main panel doesn't have neutral/ground bars big enough to accept #4. So, rather that adding a lug nut to the bars, or only attaching a few strands of the #4 to the bars, I'm thinking of snaking another #10 awg (neutral) and #8 awg (ground) into this greenfield. Is it possible and ok to do this? I'll leave the extra 2 #4 wires in case I'd like more amperage to the subpanel one day. Any ideas?
based on national electrical code table 27 for rewiring you are allowed 40% conduit fill. and table 29 the 1.25" conduit 40% fill, the total combination area of conductors is 0.60 sq.in (table 29 column 7)
now go to table 30 see how many combination of different size of conductors (column 1 and column 5) add up to be equal to 0.60 sq.in. example each #4 conductor has 0.1087 sq.in for 4-#4 the total area is 4*0.1087=0.4348 sq.in. it is less than 0.60 sq.in so you can pull 4-#4 in 1.25" conduit.
this selections is good only for rewiring not for new wiring.
