DC 300V

A figure displayed with the AC or DC before the value represents a nominal voltage with

standard tolerances (usually ±15%) included.

E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)

300Vdc

A figure with the unit (Vdc) at the end is a momentary figure without any additional

tolerances included.
