Abstract: An electrical power distribution system has a converter module having a converter to convert AC voltage from AC voltage sources to DC voltage and provide DC voltage power with adjustable maximum power values at electrical output interfaces of the converter module to a maximum module power value. It includes a power profile management device to negotiate individual power profiles with electrical consumers connectable to the electrical output interfaces, according to which individual power profiles electrical power up to a negotiated maximum power value is provided by the converter via the electrical output interface. The device detects instantaneous actual power consumption with which an individually negotiated power profile and calculates a power reserve value of the converter as the difference between negotiated maximum power value and instantaneous actual power consumption and negotiate with consumers whose power reserve value is higher than an adjustable reserve threshold value a new power profile.

Abstract: A socket insert includes a lower housing section, which incorporates a current infeed terminal, and an upper housing section, which is connected to the lower housing section, upon one of the sidewalls of which a snap-fit connecting part is arranged. The socket insert further comprises a cover plate, which is integrally connected to the upper housing section, closes the upper housing section to the exterior, and incorporates at least one device terminal which is electrically connected to the current infeed terminal. The cover plate incorporates a peripheral cover plate overhang which projects beyond the side walls of the upper housing section.
