Piktogram and classes of electroinsulating footwear<br />
Class 00 (triangulars of light brown colour) - is used on insulations where nominal voltage is not higher than<br />
500 V of alternative current or 750 V of direct current;<br />
class 0 (triangulars of red colour) – is used on instalations where nominal voltage is not higher than 1 000 V of<br />
alternative current or 1 500 V of direct current.
