im a 3rd yr elect apprentice. my neighbor is having a/c trouble.
problem: in the middle of summer when the ac has been running for about 8 hrs the breaker(main panel) for the condensing unit trips..
specs: 2,000 square ft house with 4 ton rheem split system.
cond. nameplate: minimum circuit ampacity-29amp
minimum fuse or breaker size-35amp
maximum fuse or breaker size-50amp
wire size from the cond. to disconnect-8awg
wire size from disconnect to main panel-10awg
30amp breaker in main panel for cond.
he said it only started tripping within the last yr, unit has been in for 10 yrs.
Im wondering why the electricians installed a 30 amp breaker, when the cond calls for 35amp br minimum.
Would a 40amp breaker be more appropriate????:roll:
