A persistent DC circuit breaker provides a persistent single or dual DC voltage for a power distribution circuit coupled to a power panel. A control mechanism ensures a constant and consistent DC power output from the persistent DC circuit breaker. The persistent DC circuit breaker can replace an AC circuit breaker to convert an AC power panel into a co-existing AC and DC power panel or an entire DC power panel.

Electrical power systems for distributing electrical power in arrangements including one or more gas turbine engines; one such system includes: one or more rotary electric machines, coupled to a gas turbine engine spool; converter circuits connected to the rotary electric machines converting between alternating current (ac) and direct current (dc), wherein the rotary electric machines and the converter circuits output a number R≥2 of dc power channels, each channel having an index r=(1, . . . , R); and a group of N dc load channels connected to the R dc power channels by a switching arrangement, wherein each dc load channel has an index n=(1, . . . , N) and R<N≤2R. The switching arrangement operates to connect the r-th power channel to the n-th load channel according to the relationship: $r\left(n\right)=\{\begin{array}{cc}1,& n=1\\ \frac{n}{2}\mathrm{and}\frac{n}{2}+1,& 1<n<N\mathrm{and}n=\end{array}$

A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.
