Thoughtful connector which makes a good impression

The connector has a strain relief on a plastic Maggot screw. The terminals make a good impression. In the plug itself a small leaflets is that cable must be used and how long strip the individual wires and strip them. This was also borne in mind that the earth wire must be the longest ever. In addition, the 5 safety rules for electrical work are listed on the packaging. I would use when connecting only ferrules without plastic collar, as it in the plug is perhaps a little too tight otherwise.
If the plug into a standard outlet with installation frame (eg Merten standard or studio) is located is the "nub" with the strain relief about 2 to 3 mm from the wall. This means in practice, however, also means that you need at least 20mm clearance for a power outlet behind the furniture, since even the installation frame with 12mm comes to 8mm connector added.
Since the small leaflets will possibly someday again used for stripping and I wanted dierestlichen information also I scanned the stuff. Attached as additional information. There are plug here on Amazon as set of 3 for around 12th
