[JCA1]

I have #6 CU wire that I have connected to with #6 AL wire to run power to an out building. I plan to use a 50A breaker in the main panel to feel the outbuilding, but have not installed it yet. Under my house I mounted a junction box and spliced the wires together with splicer lugs the electric supply house sold me for this purpose. These have a divider in the middle to prevent the two wires from touching and one flat blade set screw on each side to hold the wires. I used the antioxidant on the AL wire, and tightened both sides tight as I could with a regular screwdriver then wrapped the splices with about 8 wraps of electrical tape, and stuffed everything into the box. I have since been told by various sources that this was a bad idea and am "now" looking for more advice from seasoned pro's about this work of mine.
