I have a 2 section panel,with feed thru lugs. Circuits 41 and 43 enter in the left section in MC. Do I need to run a neutral with the hot from 43 to the right section, off the neutral bar, thru a chase nipple? Or should I push a loop thru the nipple and leave 43 in the right section and land 41 and the nuetral in the left section?......
