The table for the E thread contains all relevant information for threads for electrical cable glands according to DIN EN 50 262. The E thread according to the table is a relatively new standard that replaces the older armored conduit thread Pg with a newer standard. The old, imperial system has been replaced by uniform metric dimensions, as you can see in the E thread table. The main reason for the change was that the old Pg system was mainly used in Germany. The new standard according to the E thread table adapts the dimensions for cable glands to the international metric standard. The E thread has a flank angle of 60°. According to the E thread table, cable glands are primarily found on electrical installation conduits, cable glands and cable entries, junction boxes, distribution boxes, junction boxes and terminal boxes. Before starting work, always make sure that you are actually working with the correct standard according to the E thread table, as E and Pg threads are not interchangeable.
The table for the E thread for cable glands is made up of two parts. The first E thread table shows the dimensions of the mounting holes for cable glands. In the first line you will see a numerical value that indicates the nominal diameter. This is followed by the thread size, expressed by the abbreviation M for the metric standard thread and again the nominal diameter as a numerical value. In the next line you will see the thread designation according to the table E Thread. The abbreviation here is E, the numerical value corresponds to the thread size. Finally, the first table for the E thread contains information on the corresponding diameter of the mounting hole. The second table for the E thread again contains information on the nominal diameter, thread size and thread designation. These correspond to the values from the first E thread table. However, instead of the mounting hole, the second E thread table now refers to the diameter of the core hole for the threaded hole. In order to carry out a correct installation, you must adhere exactly to the values from both tables for the E thread.
