When I bought the house it had a section of triplex wire that ran to a 50A breaker with the remainder coiled in rafter space of the covered porch. (When I discovered this, the triplex was hot. That breaker is currently off and taped off.) I would like to put a sub panel in the garage, which shares the covered porch.
Can I use the existing triplex for this?
Edit: Present wire consists of 1 aluminum uninsulated, and 2 insulated wires. The insulated ones are marked CANADA I Wire 4 Aluminum 6 and some illegible stuff in orange. I need to uncoil it to find a better copy.
My suspicion is "no"
Thinking about this, it's definitely a 'no' The whole point is to get 220 for a new table saw. Which means 4 conductor wire, not 3.
Failing that, what is the best way to use the existing triplex wire to get acceptable code wire from the rafter space to the main panel without taking apart the wall?
- Cut the triplex off short of it's entry point into the house wall.
- Tape/solder conventional wire to the triplex.
- Shut off the power, disconnect the triplex from the breaker, undo the strain relieve, and try to worry it all back into the main panel box..
Do the same operation but do the feed from the main panel end.
Use the triplex to get someing more flexible through the route (fish tape? Rope?) and attach the new wire to it?
