I'm remodeling my kitchen and removing a load bearing wall. Existing triple 2x10 beam has cables that pass thru it via drilled holes. Structural engineer has spec'd a W8x24 I-beam to replace the existing triple-beam. (The I-beam will be hidden and all existing 2nd story floor joists will be re-tied into the I-beam with Simpson joist hangers. The I-beam will be packed with plywood & 2x8s.)
How should I repair/splice the cables running thru the existing wood beam, which must be cut in order to feed them thru hole(s) in the I-beam? (Until I tear out the ceiling, I do not know how many and what gauges they will be. I do know most will be 12awg, but there may also be a 10awg cable feeding a dryer on the 2nd floor.) I do know there will be little, if any, slack in the cables to work with.
I prefer a solution that will not require junction box(s)/accessibility, though I know this is almost, if not, impossible. I found such a solution on a YouTube video, but Home Depots no longer carry the Tyco cable splice kits (shown in that video @ ~$7ea) and other potential supplier's costs I found online may be cost prohibitive ($35-50 per splice), depending on how many I actually end up needing.
If junction boxes cannot be avoided, any suggestions for centralizing them and making the access more aesthetically pleasing? The ceiling is painted T&G bead boards(~6in wide planks.)
The more I look into this project, the less affordable it seems (although another big issue is how to function kitchen-less for the projected 15mo of the entire kitchen remodel project). The beam replacement is the 1st-stage of the project, upon which everything else (custom cabinet ordering, flooring, etc) needs to be complete before they can begin.
