Found a small amount of bx cable first ever. So i was wondering i found some with 3 wires and some with5 wires it seems to me that 5 wire isnt common im assuming most bx is solid wire but i did find some with 3 stranded wires will it affect recovery rate? I noticed the 5 wire bx is bigger than the 3 wire. Im assuming its ali bx cause i doubt i could bend it to see the wires then snip the metal off to get the wires out without cutting them. I only probably have 5lbs bx not sure have to weigh it out looks like i got 14 and 12awg does it come in 10awg and bigger? Whats recovery on these?
