1. A modular power distribution system to drive DC and AC electrical loads, comprising: one or more logical units in independent locations, receiving DC and AC power lines for distribution to respectively DC and AC electrical loads in all of said independent locations;one or more physical units, in each of said logical units, each of said physical units controlling and distributing DC or AC power to respectively one or more of said DC or AC electrical loads in one of said independent locations;one or more power modules in each of said one or more physical units, for distribution of DC or AC power to one of said DC or AC electrical loads, wherein each of said power modules for DC power comprises for each power line for said DC electrical loads at least a safety replaceable fuse, a solid state power switch and a by-pass manual switch;at least one master control unit for each of said one or more logical units, said master control unit being placed in one of said physical units, to control the functions of the pertaining logical unitwherein each of said physical units further comprises a power supply module, which logically controls the power distribution to the inputs of all the power modules in the pertaining physical unit and each of said power modules for DC or AC power comprises a control unit exchanging control data with the pertaining master control unit andwherein the by-pass manual switch causes an OFF, a manual and an automatic functionalities of the power module such that: when the OFF functionality is activated, the load is powered off;when the manual functionality is activated, the safety replaceable fuse is the only protection electrically connected to the current supply path; andwhen the automatic functionality is activated, the by-pass manual switch is moved to include the solid state power switch in the current supply path and the power module measures output currents, voltages and internal temperatures such that the power module is able to drive the loads activating an automatic protection in case of a short circuit, an open load and/or an out of range current, based on the measured output currents, voltages and internal temperatures. 2. A modular power distribution system as in claim 1, wherein each of said physical units comprises a supporting baseboard, having a number of physical slots to host the pertaining master control unit, power supply module, and one or more power modules, each of said physical slots being assigned a SLOT number. 3. A modular power distribution system as in claim 2, wherein said supporting baseboard comprises means for performing the following functions: locking modules of the physical unit, these modules including the one or more power modules, the power supply module and the at least one master control unit;accepting the inputs of an electrical power supply through power inputs interconnections;covering and protecting the power inputs connections;distributing electrical power to the modules of the physical unit;distributing and sharing an internal signals bus between the modules connected to the physical unit;supplying a further port to expand the internal signals bus to other baseboards of the physical units of the same logical unit;supplying ports for communications BUS of the CAN type;hosting a switch to set a Logical Unit Number;hosting a switch to set a Physical Unit Number;hosting a switch to set said SLOT number. 4. A modular power distribution system as in claim 3, wherein said master control unit comprises means for reading from the relating supporting baseboard said SLOT number, Logical Unit Number, and Physical Unit Number, so as to identify where it is installed and determine a related setup, the related setae being identified by a setup number. 5. A modular power distribution system as in claim 4, wherein, in case said related setup is missing, said master control unit communicates a SETUP missing status to all other master control units of the system, so as to enable the downloading of another setup from one of said other master control units. 6. A modular power distribution system as in claim 4, wherein said master control unit comprises means for requesting, at the start up, the SLOT number, Logical Number and Physical Unit Number of the modules connected to each of said slots of the relating supporting baseboard, and for performing the following operations: if a slot is occupied, and if the module type and setup number are the same as in the setup stored, the master control unit enables the operation of the module;in case a different setup is found, a new setup is sent to the module;in case a different module type or slot not occupied by any module is detected, said slot is disabled and an error procedure is activated. 7. A modular power distribution system as in claim 3, wherein exchanging control data between the control unit of said power modules for DC or AC power and the pertaining, master control unit, includes reading the slot number, and own data and setup, so as to perform the following operations; when setup and acknowledgement is received from the master control unit, the power module starts operating, cycling sending operational data back to the master control unit;in case no answer from the master control unit is received, the power module stays in NOT Operating Mode;if the power module looses the communication with the master control unit, it moves to a Safe Mode, continuing with the current setup. 8. A modular power distribution system as in claim 1, wherein said safety replaceable fuse is of one of the following kinds: blade automotive thermal blade automotive; glass.
