What is PG thread size?
Panzergewinde sizes are named with the prefix PG plus a nominal number which approximately corresponds to the maximum cable diameter (in millimeters) that can be passed through the conduit. Because the walls of the conduit are usually relatively thin, the thread depth is limited. Thus a thread angle of 80° is used.
