What is NYM cable?
NYM: PVC installation cable (Mantelleitung) for fixed installation, the type of DIN VDE 0250-204. Rating: U0/U 300/500 V (clause 4); laying after DIN VDE 0298-3 (clause 7). Standard: DIN VDE 0250-204:2000-12 (1 core 1,5 to 16 mm², 2 to 5 cores 1,5 to 35 mm², 7 cores 1,5 and 2,5 mm², 5.1; bare copper, solid class 1 to 10 mm², stranded class 2 from 16 mm², 5.2; mean overall diameter limits, Table 1 columns 7 and 8, e.g. 3 x 1,5 mm²: 8,2 to 9,9 mm, 5 x 2,5 mm²: 11,0 to 13,3 mm; tests, Table 2: 2 kV a.c. for 5 min on the complete cable).
NYM-J has a green-and-yellow core, NYM-O none (3.2). The letter reading below this row is the DIN VDE 0250 letter code; this row is the type as the standard defines it.
