    Default Square D - 3 grounds under one terminal

    I have started seeing Square D panels that are allowing up to 3 grounds per terminal screw. Its been limited to 2 for several years so I thought I would throw this out just in case some have not noted the change before now. Note that mixed wire size combinations are not shown.

    I noticed that also have only seen it in the new square D that has the plug in ability for the AFCI and GFCI breakers by doing that they eliminated every third screw on the grounding/grounded bar so I guess they had to make up for the lack of holes by increasing the number of conductors allowed you can watch the video about them here.
