Mains cables require proper strain relief to prevent tugging or chafing on the sides of the hole. That's a safety issue. [Edit: Another vital function of a strain relief is rotation prevention - that can tear internal mains wiring loose.] --- End quote --- Yes that seems like common sense here in the 21st century. But back 60-80 years ago, rubber grommets and special knots were quite common with attached zip-cord power entrances. I remember seeing the special knots where you zip apart the two wires (L & N) and tie a symmetrical knot. Look at some of those videos showing vintage electronic gear. I hate attached power cords (including wall-warts and line-lumps). I take special pleasure in replacing those old crumbly grommets (and even Heyco bushings) with proper IEC 60320 panel-mount connectors. I still have a nice big bag of IEC connectors that I bought at the Tektronix surplus sales. |

Me too. You can almost guarantee, the more valuable or irreplaceable the 'treasure' you're carrying, the more likely the cord is to get wrapped around your ankles! |

Captive leads of any kind are evil. I watched my father stand on an old radio power supply lead when he was carrying it once. Faceplanted and cracked a rib. Yes I did laugh >:D |

Yes also often put a knot in it or used a tiewrap, it prevents the cable from being pulled out but it does not prevent the cable from being pushed in :) Also in dusty environments those holes are dustcollectors. |
