One or two more thing to be attentive of:
Most box and breaker terminals that are aluminum or are suitable for use
with aluminum conductors are tin plated. This tin plating is easily
burned or scraped away. Without the plating, corrosion protectant
becomes vital to keep the connection secure.
Please be aware that the torque spec on the lugs has a double purpose as
aluminum wire , if too tight, will cold flow. Loose connections will
continue to heat and further loosen so the final torque should be close
to guard against both unequal expansion and cold flow.
A "proper" electrician's screwdriver already HAS an insulated shaft.
Don't ever get caught by the OSHA guys working in an electrical box
with a "common" screwdriver. You can end up with some unpaid holidays,
and possibly a hrfty fine to go with it.
A couple layers of heat-shring tubing properly applied makes a good
"electrician's" screwdriver out od a "common" one

A friend of mine, one electrical socket was not
working. I took the panel cover off, and went to
try the window air conditioner. She was standing
in the cellar watching the box. I came down stairs
and she said it had been sparking "up here",
pointing towards the upper right. The neutral
wire had loosened up. I went up and down the row
and tightened them all, and things worked fine.
