University Electrical Policy and Guidance. The low power loss figures contribute significant energy saving. 0 In: t = 180s max. In order to guarantee the total protection of the users and the installation (power supply line included) in front of any electrical hazard, it is mandatory to install a main circuit breaker (MCB) and a residual current device (RCD) upstream of the charger. Find MCB manufacturers and suppliers from China. Although metallic, they are meant only for mechanical support, and are not used as a busbar to conduct electric current, although they may provide a chassis grounding connection.
