I want to run overhead power drop using regular rubber/plastic jacketed SO (extension cord) wire. What is the proper nomenclature for the strain relief on the boxes that need to be used to meet NEC? What section of NEC describes this arrangement?
Guy
Are you referring to Twist-Lok? I don't know what the code says about it.

To me those are known as Kellum Grips. I don't think NEC requires those however for this application. Simply "Strain Relief" fittings are what the OP needs.
Borg, etc. have 1/2" romex like connectors with rubber gripping sleeves in them. Naturally I forget the name. I'm thinking this is just for the drop, with the feeds in Romex?
