Existing situation: 100 amp feeder made up of three (!) individual aluminum conductors exiting home panel through three separate 1/2" KOs (!!), in wall to crawl space, through foundation wall, multiple split-bolted splices under deck (!!!), buried to detached, steel-skin garage, up inside EMT to un-bonded panel (!!!!).
The neutral became intermittent, then open. There is grounding in the garage panel, but again, was never bonded to the neutral despite there being no EGC in the 3-wire feeder. I'm recommending that we abandon the existing conductors and run a new 4-wire feeder, rather than try to repair the existing neutral.
So, the question is: what wiring method would you use from panel, down inside the exterior wall into the crawl space, through the foundation wall, under the deck about 20 feet, in the ground about 10 feet, and up into the garage, probably with an LB through the skin if we can't easily re-use the existing EMT sleeve.
