I would add that it is a good idea to use "OX-Gard" or other similar treatment for these screw terminal connections. Keep the air out and the connection clean. Often used for dissimilar metals in one connection. I use it on all screw type clamp connections inside or out. Just to be sure corrosion doesn't get a toehold.
