To prevent failures:
Ensure that the design of your power system provides adequate power to the server.
Use dedicated AC breaker panels for all power circuits that supply power to the server.
Ensure that electrical work and installations comply with applicable local, state, or national electrical codes.
Ensure that the electrical circuits are grounded to Earth.
Provide a stable power source, such as an uninterruptable power supply (UPS) to reduce the possibility of component failures. If computer equipment is subjected to repeated power interruptions and fluctuations, then it is susceptible to a higher rate of component failure.
