Good question I have never seen that on a 4S cover. Some inspectors want the notches so the cover can't fall off if the screws are loose.
 
Look for a small raised dimple next to the slot for the screw. That's there to keep the cover from sliding off if the screw gets a little loose.:wink:
 
Must be the side "they" - the manufacturers want you to put to the inside! But really, I've wondered that myself...Maybe to confuse us. (Like the customer at the supply house who asked for a 2 gang plate - switch & recep' & said to the clerk but I need the switch on the left side. The clerk takes the cover plate back, under the counter flips the cover plate 180 degrees & hands it back to the customer. "There you go." He said. Customer walked away happy! (True story) :)
 
So that when you tighten the screw it dosnt push the cover out from under it. Just like why we wrap the wire clockwise around the terminal

So what happens when you rotate the cover 90?? The slots are the opposite directions then.

One day they will put a tag on the sod that say's "Green side up". I guess few of us are smart enough to even install a 4sq. cover correctly. They must have started to do that after the many deaths that occur each year from 4sq. blanks falling off. :rolleyes:

Caused by installing receptacles ground pin down, and having a cord plugged in only half-way, causing the cover to create an arc on a non-AFCId circuit.......;)

Why do some 4 square blanks have "Under Side" engraved in them?

I had a guy tell me a while back that an inspector had him turn the blanks stamped side in. His reason was that if the blank was painted, you could still read the UL stamp.

Seems this inspector is protecting us from those non-UL 1900 blanks that could easily bring this industry to its knees if left unchecked.
