Power terminal block and power supply apparatus

A power supply apparatus comprising:

• a power terminal block including
• a base made of an insulator,
• a plurality of power terminals insulated from each other and disposed on the base, and
• a plurality of terminal bases, each terminal base including
• a base connecting part made of a conductor and electrically coupled to the power terminals, and
• a first conductor connecting part made of a conductor,
• the first conductor connecting part being physically and electrically coupled to the base connecting part,
• the base connecting part and the first conductor connecting part being provided at different heights,
• wherein adjoining terminal bases electrically coupled to power terminals supplied with currents with different electrical potentials are coupled with the first conductor connecting parts of adjoining terminal bases disposed in different directions;
• a feeding unit coupled to an external power supply and supplying electrical power to the power terminal block;
• an overcurrent protection device blocking an overcurrent supplied from the electrical power terminal block;
• and
• a plurality of distribution boards receiving electrical power from the power terminal block via the overcurrent protection device and distributing the electrical power to coupled devices.
