So, now you know a little bit more about staples. Still hungry for more? How about learning how the first stapler came to be? Secure only one cable under each fastener, in most cases. Sometimes it is permissible to secure two 2-conductor (plus ground) cables under a single staple, for example, but it is preferable not to double up cables. It is not permissible to secure more than one 3-conductor cable under a single staple.

The electrical code limits how many wires you can safely put in an electrical box. To figure the minimum box size required by the National Electrical Code, add: Use insulated staples and fasteners. Avoid plain metal staples, and never use standard staples or other fasteners that are not designed for electrical installations. The T72 Cable Staples are just what you need to keep those cables neat and tidy, without doing any damage, yet still having a firm hold. The plastic insulated bridge on the staple ensures that the staple wire does not cut into the cable casing and damage them.

The staples the King used were a bit different than the ones we’ve described above: Lou’s staples bore his royal court’s insignia, and some claim they were made of gold and encrusted with jewels. Gawdy to us, maybe, but pretty on-brand for a King. At this point, you may be wondering what’s the standard staple that fits the standard stapler found in nearly every standard classroom and office?

For help with circuit design and making connections to your main electrical panel, we recommend you consult a licensed electrician. A stapler for the common man didn’t appear for public use until the 19th century. For whatever reason, several different people filed patents for devices designed to staple paper toward the bottom half of the 1800s.
