Nanosecond Max Current of Residual-Current Circuit Breaker

Click For Summary
SUMMARY

The discussion centers on the potential use of the Protective Earth (PE) wire in a 3-grid electric system for discharging an electromagnetic pulse (EMP) from a nuclear event. Participants debated the implications of a residual-current circuit breaker (RCCB) with a permanent maximum current of 16 Amperes and its ability to handle a 50-nanosecond high current discharge. It was concluded that EMPs can damage electronics directly, regardless of their power state, and that lightning strikes can produce similar EMP effects, albeit on a smaller scale.

PREREQUISITES
  • Understanding of 3-grid electric systems (L, N, PE)
  • Knowledge of residual-current circuit breakers (RCCB) and their specifications
  • Familiarity with electromagnetic pulses (EMP) and their effects
  • Basic principles of electricity, including Maxwell's Equations
NEXT STEPS
  • Research the specifications and limitations of RCCBs in high current scenarios
  • Study the effects of EMP on electronic devices and protective measures
  • Learn about the differences between lightning strikes and EMPs
  • Explore military and civilian EMP protection strategies
USEFUL FOR

Electrical engineers, safety professionals, and anyone involved in designing EMP protection systems for residential or commercial properties.

To protect against a nuclear EMP (NEMP) usually a big metal box is used, which is electrically connected to earth, to discharge the electrical pulse.

Most houses in europe have a 3-grid electric system, L, Neutral (N) and Protective Earth (PE).

Is it possible to use the PE wire as EMP discharge to ground?

Please keep in mind, that the PE does not go to Earth directly, but has to pass the residual-current circuit breaker (RCCB), which may be damaged by the nano-second long high current discharge.

Conclusively, what is the 50 nano-second maximum current of a residual-current circuit breaker (RCCB), which has a permanent maximum current of 16 Ampere?

I don't think any of that matters because EMP reaches your electronics directly, even if it is not plugged into the wall.

My boat was hit by lightning. The EMP destroyed almost all my electronics, even things that were turned off and even a hand-held walkie-talkie radio.

@ anorlunda
Lightning and EMP are totally different things ...

No. You need to learn some basic electricity including Maxwell's Equations.

Near (not in) a lightning strike, there is an EMP having a range of a few meters. The EMP from a nuclear explosion is similar but its range is hundreds of km.

If EMP protection is a military secret and following you cannot discuss it, please just say that and do not constantly remove comments.

Thanks
